SNC2D - Personal Study Materials

Descrição

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!

Resumo de Recurso

Questão 1

Questão
Small 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.
Responda
  • True
  • False

Questão 2

Questão
Gases 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.
Responda
  • True
  • False

Questão 3

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

Questão 4

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

Questão 5

Questão
Most of the hydrosphere is composed of freshwater.
Responda
  • True
  • False

Questão 6

Questão
The main greenhouse gases—such as carbon dioxide, methane, and water vapour—naturally occur in the atmosphere at very low levels.
Responda
  • True
  • False

Questão 7

Questão
Heat 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]
Responda
  • radiation
  • convection
  • conduction
  • black
  • white

Questão 8

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

Questão 9

Questão
The greenhouse effect occurs because the ultraviolet radiation cannot escape Earth’s atmosphere and warms the planet further.
Responda
  • True
  • False

Questão 10

Questão
When the earth absorbs the sun’s radiant energy, it is transformed into heat energy, warming the planet.
Responda
  • True
  • False

Questão 11

Questão
It would be better if we could get rid of all carbon dioxide.
Responda
  • True
  • False

Questão 12

Questão
Nitrogen and Ozone are greenhouse gases.
Responda
  • True
  • False

Questão 13

Questão
Most of our atmosphere consists of nitrogen and oxygen.
Responda
  • True
  • False

Questão 14

Questão
The production and burning of fossil fuels like coal and oil are significant contributors to the production of greenhouse gases.
Responda
  • True
  • False
