1Small changes in earth’s orbit and periodic changes in the sun’s energy aren’t enough to have caused significant climate changes in the past.
- AVerdadero
- BFalso
2Gases such as argon, carbon dioxide, water vapour and methane make up a tiny percentage of the air and don’t play an important role in regulating our climate.
- AVerdadero
- BFalso
3The troposphere is a layer of the atmosphere that is closest to the earth’s surface and has a large impact on climate.
- AVerdadero
- BFalso
4The saltwater oceans don’t impact the earth’s climate in a significant way because freshwater is more abundant.
- AVerdadero
- BFalso
5Most of the hydrosphere is composed of freshwater.
- AVerdadero
- BFalso
6The main greenhouse gases—such as carbon dioxide, methane, and water vapour—naturally occur in the atmosphere at very low levels.
- AVerdadero
- BFalso
7Heat transfer without a medium: [blank_start]radiation[blank_end]
Heat transfer in a gas or liquid: [blank_start]convection[blank_end]
Heat transfer in a metal rod: [blank_start]conduction[blank_end]
Colour that absorbs a large amount of heat: [blank_start]black[blank_end]
Colour that reflects a large amount of heat: [blank_start]white[blank_end]- Aradiation
- Bconvection
- Cconduction
- Dblack
- Ewhite
8The greenhouse effect is a naturally occurring process and is necessary for life on Earth, so it can’t be a problem.
- AVerdadero
- BFalso
9The greenhouse effect occurs because the ultraviolet radiation cannot escape Earth’s atmosphere and warms the planet further.
- AVerdadero
- BFalso
10When the earth absorbs the sun’s radiant energy, it is transformed into heat energy, warming the planet.
- AVerdadero
- BFalso
11It would be better if we could get rid of all carbon dioxide.
- AVerdadero
- BFalso
12Nitrogen and Ozone are greenhouse gases.
- AVerdadero
- BFalso
13Most of our atmosphere consists of nitrogen and oxygen.
- AVerdadero
- BFalso
14The production and burning of fossil fuels like coal and oil are significant contributors to the production of greenhouse gases.
- AVerdadero
- BFalso

- 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!
