which of the following would be a positive feedback mechanism? choose all that apply. global warming increases cloud cover, which traps heat on earth, which increases global warming. deforestation increases reflectivity and decreases the amount of absorbed solar radiation. global warming melts sea ice, which decreases reflectivity and increases the amount of absorbed solar radiation. global warming increases cloud cover, which reflects solar radiation, which decreases global warming. burning coal increases aerosols, which increases reflectivity and decreases global warming.
Global warming is the unusually rapid increase in Earth's average surface temperature over the past century primarily due to the greenhouse .
The darker ocean absorbs more heat, which leads to greater ice melting and a general warming of the planet as the atmosphere and sea ice warm. The reaction from ice-is overwhelmingly good. The propensity of heat to increase the quantity of water vapour in the atmosphere, which in turn leads to additional warming, is the primary positive feedback in global warming.A feedback loop in climate change is something that accelerates or a warming trend. A temperature rise is sped up by positive feedback and slowed down by negative feedback. The surface feedback is an illustration of a favourable feedback.

Walking among the top canopy in a tropical rainforest requires _______.
a. bridges suspended almost 100 feet off the ground b. bridges suspended almost 60 feet off the ground c. bridges suspended almost 20 feet off the ground d. no special conditions
Answer:
a. bridges suspended almost 100 feet off the ground
Explanation:
It is difficult to determine exactly how high a bridge would have to be suspended above the ground to walk among the top canopy in a tropical rainforest, as the height of the canopy can vary depending on the specific location and the type of trees present. In general, however, the canopy of a tropical rainforest is typically found at a height of around 30-40 meters (100-130 feet) above the ground. This means that a bridge would need to be suspended at least this high in order to allow people to walk among the canopy. Keep in mind that this is just a general estimate, and the actual height of the bridge would depend on the specific conditions of the forest where it is located.

The region in the United States that receives the most extreme (highest rain rate) precipitation is the southeast. The southeast region of the United States includes states such as Florida, Georgia, and Alabama, and it is known for its hot, humid climate and heavy rainfall. This region is particularly susceptible to hurricanes and other severe weather events, which can produce high levels of rainfall and cause widespread flooding.
granite continental crust beneath washington and oregon (usa), over the subducting juan de fuca plate?
Answer:
The granite continental crust beneath Washington and Oregon is part of the North American Plate, which is the largest and most stable of the Earth's tectonic plates. The North American Plate extends from the Arctic Ocean in the north to the Caribbean Sea in the south, and it covers most of North America, including the region beneath Washington and Oregon.
The Juan de Fuca Plate is a smaller tectonic plate that is located off the coast of the Pacific Northwest, beneath the waters of the Pacific Ocean. The Juan de Fuca Plate is moving slowly towards the northwest, and it is subducting, or diving, beneath the North American Plate. This process of subduction occurs where two plates meet and one plate is pushed beneath the other, and it can create significant geological activity, including the formation of mountains and earthquakes.
The granite continental crust beneath Washington and Oregon is not directly affected by the subduction of the Juan de Fuca Plate, as the granite crust is part of the North American Plate and is not being subducted. However, the subduction of the Juan de Fuca Plate can indirectly affect the granite crust by creating stresses and strains within the Earth's crust, which can lead to the formation of earthquakes and other geological phenomena in the region.
volcanic ash discovered by romans about 300 bc that, when mixed with water, would harden to an unusually strong material, even when fully submerged under water?
Volcanic ash discovered by Romans about 300 BC that, when mixed with water, would harden to an unusually strong material, even when fully submerged under water is called Pozzolanic ash.
Pozzolanic ash is a naturally occurring siliceous or siliceous-aluminous substance that reacts with calcium hydroxide at room temperature in the presence of water. High silica and alumina content volcanic ash was discovered near Pozzuoli, Italy. When combined with lime, water, sand, and rock, the resultant compound hardened to an incredibly durable substance that could withstand being completely submerged in water.
Any volcanic material (pumice or volcanic ash) that is used as a pozzolan and is primarily made of fine volcanic glass is included in the contemporary definition of pozzolana. Please take note of the distinction between the terms pozzolan and pozzolana, the former of which may only be used to describe pozzolans of volcanic origin, principally made of volcanic glass, and the latter of which has no relation on the specific origin of the material.

the sierra nevada mountain range in california is young and composed almost entirely of granite; what do you expect the landscape to look like?
Answer:
That the landscape is characterized by rugged, rocky terrain.
Explanation:
The Sierra Nevada mountain range in California is young and composed almost entirely of granite, so it is likely that the landscape is characterized by rugged, rocky terrain. Granite is a type of rock that forms from the cooling and solidification of molten magma deep beneath the earth's surface. It is a hard and durable rock that is resistant to weathering and erosion, which makes it a common component of mountain ranges. The Sierra Nevada mountain range is relatively young, meaning that it has not had as much time as some older mountain ranges to be worn down by erosion. As a result, the landscape is likely to be dominated by steep, rocky peaks and valleys, with few flat areas or smooth, rolling hills. There may also be many sharp cliffs and ravines, as well as numerous rivers and streams. Overall, the landscape of the Sierra Nevada mountain range is likely to be rugged and imposing, with a distinctive, rocky character.

If the southern hemisphere is getting indirect sunlight, what kind of light is the northern hemisphere receiving?
If the southern hemisphere is receiving indirect sunlight, the northern hemisphere is receiving direct sunlight. The Earth is tilted on its axis, which causes the northern and southern hemispheres to receive different amounts and types of sunlight depending on the season. During the summer months in the northern hemisphere, the Sun is directly overhead, which results in more intense and direct sunlight. In the southern hemisphere, the Sun is lower in the sky, which results in indirect sunlight that is less intense and more diffuse. During the winter months, the situation is reversed, with the northern hemisphere receiving indirect sunlight and the southern hemisphere receiving direct sunlight.

Which of the following would be an implication of maquiladoras?
A. High prices for exported goods manufactured in maquiladoras.
B. Loss of jobs for American workers.
C. High wages demanded by Mexican citizens for relocation.
D. Cooperation between the U.S. and Mexico is minimized.
Answer:
B. Loss of jobs for American workers.
Explanation:
Loss of jobs for American workers is an implication of maquiladoras. Maquiladoras are factories located in Mexico that are owned by foreign companies, typically from the United States. These factories take advantage of Mexico's lower labor and production costs to manufacture goods that are then exported back to the United States and other countries. One implication of this system is that it can result in the loss of jobs for American workers, as companies move their production to Mexico in order to save money. This can have negative effects on the American economy and on workers who are displaced by the closure of factories in the United States.
In which type of rock would a scientist most commonly find a fossil of a triceratops?
Due to their location in shale and siltstone that has volcanic ash radiometrically dated at 70 million years ago, the Triceratops dinosaur fossils are around 70 million years old.
Usually, sedimentary rocks include fossils, however rarely, low-grade, fine-grained metamorphic rocks will as well. It's possible that the fossils have been removed, leaving molds in the surrounding rock, or that the molds have been filled with different materials in the past, creating castings of the original fossils. This well-known ceratopsian, or horned dinosaur, was a herbivore despite having a fearsome look. One of the final non-avian dinosaurs to emerge before the catastrophic extinction catastrophe that took place 66 million years ago was Triceratops, which is Latin meaning "three-horned face." Researchers use some kind of clock to ascertain the date when a rock or fossil was generated in order to calculate its age. Geologists frequently rely on the accuracy of radiometric dating techniques, which are based on the natural radioactive decay of certain elements like potassium and carbon.

The statement, "Romans planted grapes on hillsides so that the ripe grapes would role down to the valley floor, which facilitated easy collection and processing." is true.
The Middle East is typically referred to be the grape's native land, and grape cultivation there has existed for 6,000–8,000 years. One of the earliest domesticated bacteria, yeast, is naturally present in the skin of grapes, which is how alcoholic drinks like wine were first discovered. There is 8,000-year-old archaeological evidence from Georgia demonstrating the importance of winemaking to human history.
The world's oldest winery, which goes back to around 4000 BC, is located in Armenia. By the ninth century AD, Shiraz was well known for producing some of the greatest wines in the Middle East.

what aspect of the volcanic massive eruption that produced the siberian traps contributed most to global warming?
The Siberian Traps, also known as a vast igneous province in Siberia, Russia, are a sizable expanse of volcanic rock.
One of the largest known volcanic episodes in the past 500 million years produced the huge eruptive event that created the traps.
The Permian-Triassic boundary, also known as the P-T boundary, which took place at 251.9 million years ago, was crossed by the eruptions, which lasted for almost two million years. The most severe extinction event recorded in the geologic record, the Permian-Triassic extinction event, is thought to have been mostly caused by the Siberian Traps.

when the northern hemisphere is tilted toward the sun, how does this affect the length of our day?
Our planet stays quite close to the same distance from the sun throughout the year thanks to the Earth's hardly elliptical orbit. In fact, during the summer in the Northern Hemisphere, Earth is a little further away from the sun.
The hemisphere that is inclined toward the sun, whether it be the Northern or Southern Hemisphere, receives more direct sunlight. Additionally, the hemisphere slanted toward the sun has more daylight hours than the hemisphere tilted away from it. Hence, the daytime increases.
The hemisphere tilted toward the sun receives more solar radiation and experiences greater temperatures as a result of more hours of daylight and direct sunshine. Summer is experienced between the equator and 90°N (the North Pole) latitudes when the Northern Hemisphere is turned toward the sun.
