Which of the following continents was covered by glaciers during the Pleistocene ice age quizlet?

Which of the following continents was covered by glaciers during the Pleistocene ice age quizlet?

Africa was covered by glaciers during the Pleistocene ice age.

Why did the glaciers melt in the ice age?

When less sunlight reaches the northern latitudes, temperatures drop and more water freezes into ice, starting an ice age. When more sunlight reaches the northern latitudes, temperatures rise, ice sheets melt, and the ice age ends.

Are glaciers left over from the ice age?

Yes and no. Many formed as recently as the start of the Little Ice Age, approximately 1,000 years ago. Others may date from other post-Pleistocene colder climate events.

Why entering an interglacial period resulted in an increase in biodiversity on Earth?

Explain why entering an interglacial period resulted in an increase in biodiversity on Earth. Therefore, when the ice age ended and glaciers retreated the more hospitable grasslands and forests that developed hosted greater biodiversity.

What are some environmental factors that can cause changes in ecosystems?

Some environmental factors that can cause changes in ecosystems are extreme weather, disease, land use change, invasive species, and pollution. Explain how changes in land use can impact an ecosystem. Changes in land use can have a great impact on ecosystems.

What happens when the levels of greenhouse gases in Earth’s atmosphere increase?

An increase in the atmospheric concentrations of greenhouse gases produces a positive climate forcing, or warming effect. From 1990 to 2015, the total warming effect from greenhouse gases added by humans to the Earth’s atmosphere increased by 37 percent

Is the greenhouse effect good or bad for the earth?

Greenhouse gases are gases that can trap heat. They let sunlight pass through the atmosphere, but they prevent the heat that the sunlight brings from leaving the atmosphere. Overall, greenhouse gases are a good thing. Without them, our planet would be too cold, and life as we know it would not exist

Which gas has lowest global warming potential?

Ammonia

How do you get methane out of the atmosphere?

If methane is to be stripped out of the atmosphere, taking advantage of natural air flow provides a viable solution. Natural processes destroy roughly 10% of the methane in the atmosphere every year6

How long does methane gas stay in the atmosphere?

approximately 9 years

Why is methane bad for the atmosphere?

When methane is produced from non-fossil sources such as food and green waste , it can literally take carbon out of the air. However, methane that is released into the atmosphere before it is burned is harmful to the environment. Because it is able to trap heat in the atmosphere, methane contributes to climate change.

Which country has lowest carbon footprint?

Tuvalu

Which country is the biggest polluter?
