Answer:
The fossil records.
Explanation:
The key observational evidence that supports the idea that life on Earth has evolved through time is the fossil record. The fossil record is the collection of fossils that have been preserved in rock formations around the world, and it provides a detailed record of the history of life on Earth.
The fossil record shows that the forms of life on Earth have changed over time, and that different species have appeared and disappeared in a pattern that is consistent with the principles of evolution. For example, the fossil record shows that early forms of life, such as single-celled organisms, were simple and relatively unspecialized, while more complex and specialized forms, such as dinosaurs and mammals, appeared later in the fossil record.
The fossil record also shows that many species of organisms have evolved over time, changing and adapting to their environments in response to natural selection. This process of evolution is supported by other lines of evidence, such as the study of genetics and the development of new species through artificial selection.
Overall, the fossil record is a key piece of evidence that supports the idea of evolution, and it provides a wealth of information about the history of life on Earth and the processes that have shaped the diversity of life on the planet.

Which of the following land forms is created by a destructive force? (there is more than 1 answer)
A slump
B creep
C delta
D sand dune
E canyon
The energies of both creation and destruction combine to create landforms. While weathering and erosion are destructive processes, crustal deformation, volcanic eruption, and sediment deposition are constructive.
What constitutes a damaging force, specifically?Weathering and erosive forces are two examples. The surface features of the Earth are often broken down by these forces. Existing land types frequently disappear due to destructive causes.
Why does weathering cause destruction?Because they disassemble landforms and obliterate the already-existing features, weathering and erosion are destructive forces (very slowly and over time). While erosion involves the movement of parts of rock and landforms, weathering involves the disintegration of rock or a landform.

which of the following is not associated with a supercell thunderstorm? a. multiple downdrafts b. no vertical wind shear c. tornado d. mesocyclone
The correct answer is d. mesocyclone is not associated with a supercell thunderstorm.
The typical characteristics of classic supercells over the Plains states include being large horizontally and tall vertically, containing deep mesocyclones (rotating updrafts), frequently producing large hail, damaging winds, and occasionally weak to violent tornadoes. These characteristics have been extensively studied and documented. The vertical wind shear (and helicity) and CAPE (instability) of supercells and tornadoes are moderate to intense, respectively (Fig. A mesocyclone, a deep and enduring revolving updraft, is what distinguishes a supercell from all other thunderstorm forms. Supercell thunderstorms may linger for several hours if the conditions are right. Non-supercell thunderstorms are those with an updraft that is not spinning. These storms don't rotate because there isn't enough variation in wind speed and direction with height.

1.The meandering stream has one channel that winds through this valley, so the distance when the "stream flows" is greater as the crow flies.
2.Erosion and deposition are responsible for many landforms. Erosion is the transport of sediments. Flowing water is a very important agent of erosion. Flowing water can erode rocks and soil. Meandering streams occur in areas covered by low elevation and smooth, softer sediments.
3.The stream starts out mostly straight, but over time one of the banks erodes, and as it descends to the opposite bank, it becomes a very winding, serpentine, or meandering stream.
4.Moving water also picks up and carries particles of soil and rock. The ability to erode is affected by the velocity, or speed, of the water. The size of the eroded particles depends on the velocity of the water.In muddy streams, the highest water velocity is on the outer banks.
5.This leads to more erosion of the outer banks and this part is constantly moving outwards.
6. Congo River looks to be a mix of braided and meandering river. At the same time, the water velocity is the lowest on the inner bank, which leads to the deposition of entrained material, so this part is constantly growing inward.

Why does the age of oceanic crust increase as the distance from the ocean ridge increases?
Answer:
Because oceanic crust is continually being created at the ocean ridge and then gradually moves away from the ridge over time.
Explanation:
The age of oceanic crust increases as the distance from the ocean ridge increases because oceanic crust is continually being created at the ocean ridge and then gradually moves away from the ridge over time. The ocean ridge is a long, underwater mountain range that runs along the bottom of the ocean, and it is the site of intense volcanic activity. This volcanic activity creates new oceanic crust, which is made up of layers of molten rock that cool and solidify as they move away from the ocean ridge. Over time, the oceanic crust moves further and further away from the ocean ridge, and as it moves, it cools and becomes older. This is why the age of oceanic crust increases as the distance from the ocean ridge increases - the further the crust is from the ridge, the older it is.

What are sedimentary rocks.?Generally, Clastic sedimentary rocks are rocks that are composed of broken pieces of preexisting rocks. They are formed through the process of weathering, erosion, and transportation of these rock fragments, which are then deposited and cemented together.
Conglomerate and breccia are both types of clastic sedimentary rocks that are made up of large, coarse-grained rock fragments, while sandstone is a type of clastic sedimentary rock that is made up of smaller, finer-grained rock fragments (i.e., sand). Coquina, on the other hand, is a type of sedimentary rock that is made up of shells and shell fragments, rather than rock fragments, and is therefore not classified as a clastic sedimentary rock.

as the cenozoic proceeded, from about 65 million years until the start of the ice ages, what happened to earth's temperature?
Answer:
Earth's temperature gradually cooled.
Explanation:
As the Cenozoic era proceeded from about 65 million years ago until the start of the ice ages, Earth's temperature gradually cooled. The Cenozoic era, which spans the time from the end of the dinosaurs to the present day, is characterized by a series of major climatic changes, including the transition from a warm, tropical climate to a cooler, more temperate climate.
There are several factors that may have contributed to the cooling of Earth's climate during the Cenozoic era. One possible factor is the changing composition of the Earth's atmosphere, as the concentration of greenhouse gases, such as carbon dioxide and methane, may have declined over time. This could have led to a reduction in the amount of heat trapped in the atmosphere, causing the Earth's surface to cool.
Another possible factor is the movement of the Earth's continents, which can affect the global climate by changing the distribution of land and water on the planet's surface. As the continents moved and shifted over time, they may have created new patterns of ocean currents and wind patterns, which could have affected the Earth's climate.
Finally, the evolution of plant and animal life on Earth may also have played a role in the cooling of the planet's climate. As plants and animals adapted to the changing environment, they may have altered the composition of the Earth's atmosphere and the global climate in ways that contributed to the cooling trend.
Overall, the exact causes of the cooling of Earth's climate during the Cenozoic era are not fully understood, and the subject is a topic of ongoing research and debate among scientists.
The Cenozoic era experienced a warm climate initially, but towards the end, the Earth's temperature started to cool, leading to the start of the Ice Ages.
During the Cenozoic era, which started about 65 million years ago and lasted until the onset of the Ice Ages, the Earth's temperature underwent significant changes. Initially, the Cenozoic was a time of global warming, where the average global temperature was much warmer than it is today. However, during the late Cenozoic, the Earth's climate became gradually cooler, leading to the start of the Ice Ages.
These temperature and climate shifts were likely caused by the movement of the Earth's tectonic plates, which can influence global wind patterns, sea levels, and the amount of sunlight reaching the Earth's surface.

which is the single greatest obstacle to slowing climate change? group of answer choices having scientists decide on a definition of climate change global energy demand, particularly in energy-hungry countries such as the united states, china, and india the growing population of the poorer nations in the world proper climatic changes a lack of data portraying the effects of climate change
Opinionated answer. I hope that whatever you answer is not marked wrong, as the entire question is asking for an opinion
My Answer:
A lack of data portraying the effects of climate change.
I believe the lack of data portraying the effects of climate change is the largest obstacle in overcoming climate change due to it making it difficult for policymakers and the general public to understand the full extent of the problem and the need for urgent action. Climate change is a complex and multifaceted problem, and it is challenging to collect, analyze, and interpret the vast amounts of data that are needed to accurately assess its impacts. One of the reasons why there is a lack of data on the effects of climate change is that the impacts of climate change are not always immediately visible or easily measurable. Many of the impacts of climate change, such as sea level rise, changes in precipitation patterns, and the spread of diseases, are gradual and may take years or even decades to manifest. In addition, the effects of climate change can vary greatly depending on the location, the time of year, and the specific environmental conditions. Another reason why there is a lack of data on the effects of climate change is that the data that are available are often incomplete or difficult to interpret. Many of the data sources that are used to study climate change, such as satellite images, weather station data, and environmental monitoring networks, are expensive and time-consuming to collect and analyze, and they may not provide a complete picture of the impacts of climate change. Overall, the lack of data on the effects of climate change is a major obstacle in overcoming the problem, as it makes it difficult to accurately assess the extent of the problem and to develop effective solutions. To overcome this obstacle, it is essential to invest in research and data collection efforts that can provide a more comprehensive understanding of the impacts of climate change and the best ways to address them.
Write the equation of the line that passes through A(8,11) and is parallel to y=1/2x+7
The equation of the line is y = 1/2(x + 14).
The line y = 1/2x + 7 has a slope of 1/2. Since parallel lines have the same slope, the slope of the line to be found is 1/2. The points are (8,11), that is x = 8 and y = 11.
Formula:
y - y1 = m(x - x1)
where,
x1 = 8
y1 = 11
m = 1/2 [slope]
Substituting in the formula,
y - 11 = 1/2(x - 8)
2(y - 11) = x - 8
2y - 22 = x - 8
2y = x - 8 + 22
2y = x + 14
y = 1/2(x + 14)
Therefore, the equation of the line is y = 1/2(x + 14).

explain how the shape of the earth, and air and oceanic circulation determine the weather and hence influence the geographic distribution of biomes on the earth.
The shape of the earth, air and oceanic circulation determine the weather as the world's seas contribute to the planet's overall warmth, which has an impact on weather and climate.
In tropical regions near the equator, where it acts as a huge, heat-retaining solar panel, the ocean absorbs the majority of solar radiation. The atmosphere prevents heat from escaping into space after sunset while land regions also absorb a little quantity of sunlight.
The phenomenon of water molecules freely interacting with the air when they are heated is known as evaporation. Rain and storms arise as a result of the constant evaporation of ocean water, which also increases the warmth and humidity of the surrounding air and is then carried by trade winds. In reality, the ocean is where the bulk of rainfall that showers on land comes from.
