Climate Change

Question 1

Which substance(s) have been added by humans to the atmosphere to help trigger climate change?

Revolt · Accepted Answer

greenhouse gases

Question 2

Which ideas did you include in your answer? Check all that apply.

Revolt · Accepted Answer

A layer of ice represents one year of snow.; A ring in a tree ring represents one year of growth.; Each layer and ring can give information about the climate for that year.

Question 3

Complete the paragraph to describe how scientists obtain information about past climates.

Revolt · Accepted Answer

Glaciologists, geochemists, and climatologists study ice layers to learn about past climates. Distinct ice layers are caused by . When studying ice layers, scientists use to measure isotopes of certai: seasonal changes; Glaciologists, geochemists, and climatologists study ice layers to learn about past climates. Distinct ice layers are caused by . When studying ice layers, scientists use to measure isotopes of certai: spectrometers; Glaciologists, geochemists, and climatologists study ice layers to learn about past climates. Distinct ice layers are caused by . When studying ice layers, scientists use to measure isotopes of certai: temperature

Question 6

Explain how layers that form in ice are similar to tree rings.

Revolt · Accepted Answer

Both ice layers and tree rings are similar because they form individual annual layers that represent a single year of history. In ice cores, a new layer is formed by each year's snowfall, while in trees, a new ring represents one year of growth. Scientists can study both to determine information about the climate and environmental conditions of the past.

Question 7

Why are physicists interested in studying Europa? Check all that apply.because it is a moon of Saturnbecause it is covered in icebecause it has a deep ocean beneath icebecause there is a chance it hosts lifebecause it has an atmosphere similar to Earth

Revolt · Accepted Answer

because it is covered in ice; because it has a deep ocean beneath ice; because there is a chance it hosts life

Question 8

An atmospheric scientist used a high-resolution camera to take images of snowflakes during a snowstorm. The scientist observed that the snowflakes were heavily rimed.What can the atmospheric scientist infer about the snowstorm that was happening at that time?

Revolt · Accepted Answer

The storm was deep and turbulent.
