Which factors add to the greenhouse effect and are caused by human activities? Select two options. (This question requires Two answers)
A.a decrease in the amount of dust in the atmosphere
B.a decrease in the amount of water on Earth’s surface
C.an increase in gases in the atmosphere that absorb heat
D.an increase in surfaces that radiate energy into the atmosphere
E.an increase in the amount of solar radiation that reflects into space
Answer:
There is overwhelming evidence that human activities, especially burning fossil fuels, are leading to increased levels of carbon dioxide and other greenhouse gases in the atmosphere, which in turn amplify the natural greenhouse effect, causing the temperature of the Earth's atmosphere, ocean, and land surface to.Human activities contribute to climate change by causing changes in Earth's atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to the atmosphere.
Explanation:
EXAMPLES: Burning of Fossil Fuels: Fossil fuels like coal, oil and natural gas have become an integral part of our life. ... Deforestation: Forests hold a major green area on the planet Earth. ...

Which best defines the population growth rate?
A. a. (birth rate + immigration) - (death rate + emigration)
B.(birth rate + fertility rate) - (death rate )
C.birth rate - death rate
Answer:
A a(birth rate+immigration)-(death rate)
A. (birth rate + immigration) - (death rate + emigration) best defines the population growth.
What is population growth?Population expansion is the term used to describe the increase in human population. Most of human history was marked by a rather stable population. However, innovation and industrialization made energy, food, water, and medical care more reliable and accessible.
The human population has grown dramatically over the last century. It has mostly accomplished this by producing copious amounts of food and figuring out how to deal with sickness. There may have been only a million people on the planet when mankind first developed agriculture ten thousand years ago.
Despite the fact that every demographic pyramid is different, most fall into one of three categories: expansive (young and rising), constrictive (elderly and shrinking), or stagnant (little or no population growth).

The picture below shows a simple model of the rock cycle. Use the picture to answer any questions that follow.Which events at point 6 could transform sedimentary rock into igneous rock?
Extreme winds and storms weather the sedimentary rock into particles, which collect in rivers and are compacted into igneous rock.
Rising oceans erode mountains of sedimentary rock into particles, which sink and get compacted into layers that form igneous rock.
Tectonic plates drive sedimentary rock under Earth's surface, where it melts into magma and turns into igneous rock as it cools.
Shifting tectonic plates push the sedimentary rock toward the poles, where it freezes and hardens into igneous rock.
Answer:
Tectonic plates drive sedimentary rock under Earth's surface, where it melts into magma and turns into igneous rock as it cools.

Which of these locations is most likely to experience moderate climate throughout the year?
Answer:
b
Explanation:
The location that is most likely to experience moderate climate throughout the year is C.
The location C of the map will experience moderate climate because it is a coastal region of the map.
Moderate climate weather is described as a weather condition that occurs during the day, as cool air from sea rush towards the land and during night, as cool air from the land rush towards sea.
Because location C is a coastal region which means that the location is surrounded by land which better absorbs and radiates heat much faster than sea.
Therefore, the location that is most likely to experience moderate climate throughout the year is C.

Which best explains how coal deposits formed?
A. Millions of years of pressure and heat turned decaying animals
and plants into coal.
B. Natural gas solidified underground, creating coal.
C. Heat from the sun transformed decaying animals into coal over
millions of years.
D. Dead plants compacted underground for hundreds of ylaars
eventually turned into coal.
Answer:
A: Millions of years of pressure and heat turned decaying animals and plants into coal.
Millions of years of pressure and heat turned decaying animals and plants into coal. Therefore, option (A) is correct.
What is coal?Coal is a fossil fuel that is formed from the remains of ancient plants and animals that have been buried and subjected to high temperatures and pressure over millions of years. As layers of sediment and rock accumulate over time, they compress the organic material and trap it beneath the Earth's surface.
Over time, the heat and pressure cause the organic material to break down and undergo a series of chemical changes, eventually forming coal. This process is known as coalification and can take millions of years to complete.
