4.3 Study Guide

Question 1

What are greenhouse gases?

Answer 1

Greenhouse gases are the gases in the atmosphere that raise the surface temperature of planets.

Question 2

What do Greenhouse Gasses do?

Answer 2

They absorb the sun’s heat that radiates from the Earth’s surface, trap it in the atmosphere and prevent it from escaping into space.

Question 3

What is the greenhouse effect?

Answer 3

The greenhouse effect happens when greenhouse gases in a planet’s atmosphere heat the planet from losing heat to space, raising its temperature.

Question 4

Why is the Greenhouse Gas Effect important and how have human affected it?

Answer 4

The green house effect is important so that the plant is suitable for life. Humans have effected through deforestation, natural Gasses, and fossil fuels.

Question 5

What do ice cores tell us about the patterns of CO2 and temperature for the past 800,000 years?

Answer 5

The general temperature of the planet has gone up as well as the CO2 levels in the atmosphere.

Question 6

What is the difference between positive and negative feedback?

Answer 6

A positive feedback’s output enhances the initial disturbance while, a negative feedback’s output lessens the initial disturbance.

Question 7

Analyze/make predictions based on a diagram of a climate change feedback cycle (CO2, methane, water vapour, etc from handout would give good practice)

Answer 7

Look at handout.

Question 8

When sunlight reaches the earth what can it heat?

Answer 8

The land, oceans, and atmosphere.

Question 9

What happens when a lot of Greenhouse Gasses enter the atmosphere?

Answer 9

The temperature goes up.

Question 10

What are two examples of photon waves that come in through outer space?

Answer 10

The sun energy/light energy and infrared radiation.

Question 11

What does it mean when the Earth emits the same amount of energy that it absorbs?

Answer 11

It’s energy budget is balanced.

Question 12

Is there more or less direct sunlight in the summer?

Answer 12

There is more direct sunlight in the summer.

Question 13

Is there more or less direct sunlight in the winter?

Answer 13

There is less direct sunlight in the winter.

Question 14

What are some examples of Greenhouse Gasses?

Answer 14

CH4 or methane
CO2 or Carbon Dioxide
and H2O or Water.

Question 15

Is there more or less precipitation and temperature changes on the coast.

Answer 15

There is generally less precipitation and less temperature changes on the coast.

Question 16

Is there more or less precipitation and temperature changes inland?

Answer 16

There is generally high precipitation and more temperature changes inland.

Question 17

Describe the conditions windward.

Answer 17

Very damp with quite a bit of precipitation.

Question 18

Describe conditions leeward.

Answer 18

Very dry and desert like.

Question 19

What is the natural point of an organism or thing but, usually referring to temperature.

Answer 19

It is called the set point.

Question 20

What is the difference between climate and weather?

Answer 20

Climate describes the typical weather conditions in an entire region for a very long time—30 years or more while, weather is the temporary conditions in temperature, precipitation, wind, ocean current, and more.
