SNC2D - Personal Study Materials

Quiz by D. H., created more than 1 year ago

Hello! This is a study set I made for my science class. The class is at the Ontario Grade 10 University/Academic level with the course code SNC2D. Questions, answers, and explanations are directly copied from practice quizzes in the course and will cover topics like climate, chemistry, biology, and optics (physics). I'll update this with every quiz I get in my course!

Select one of the following:

Explanation

Question 3 of 14

The troposphere is a layer of the atmosphere that is closest to the earth’s surface and has a large impact on climate.

Select one of the following:

Explanation

Question 4 of 14

The saltwater oceans don’t impact the earth’s climate in a significant way because freshwater is more abundant.

Select one of the following:

Explanation

Question 5 of 14

Most of the hydrosphere is composed of freshwater.

Select one of the following:

Explanation

Question 6 of 14

Explanation

Question 8 of 14

The greenhouse effect is a naturally occurring process and is necessary for life on Earth, so it can’t be a problem.

Select one of the following:

Explanation

Question 9 of 14

The greenhouse effect occurs because the ultraviolet radiation cannot escape Earth’s atmosphere and warms the planet further.

Select one of the following:

Explanation

Question 10 of 14

When the earth absorbs the sun’s radiant energy, it is transformed into heat energy, warming the planet.

Select one of the following:

Explanation
