Climate Change: kids | Treevengers

Earth, The planet in the solar system that we live on is facing the detrimental effect of climate change.

Climate change/Global warming is a gradual increase in the earth's temperature due to the greenhouse effect caused by increased levels of greenhouse gasses in the atmosphere.

Is this caused by human activities?

• Yes, It is caused by human activities

• No, It is natural

The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and by greenhouse gases.

Is the greenhouse effect necessary?

• Yes

• No

Renewable sources of energy come from sources or processes that are constantly replenished/are sustainable.

They are clean/eco-friendly sources of energy.

Which of the following is NOT a renewable source of energy

• Solar energy

• Wind energy

• Fossil Fuels (coal and petroleum)

• Hydropower

The ozone layer in our atmosphere acts as a protective blanket and prevents harmful UV rays from the sun from reaching the earth.

Due to chemicals released by human activities, the ozone layer is now getting depleted.

What may be the effects of this?

• Sun rays will not reach the earth

• Harmful UV rays will reach the earth's surface

• The earth will cool down

The arctic ice cap is melting which is deadly for creatures like polar bears that depend on the ice.

Why is the arctic ice cap melting?

• because of photosynthesis

• because of a rise in temperature due to climate change

• because of polar bears

• because the sun is very hot

Non-biodegradable substances are not capable of being broken down by the action of living organisms easily.

Which of the following is a non-biodegradable material?

• cotton

• wood

• fruit peels

• Plastic

Is recycling a good practice?

• yes

• No

Deforestation involves chopping down trees and clearing forest areas for our needs. The most concentrated deforestation occurs in tropical rainforests.

Is deforestation beneficial for the environment?

• No

• Yes

Trees help maintain the levels of carbon dioxide and oxygen in the air (because of photosynthsis). This is why deforestation (cutting down trees) is bad for the environment.

State true or false

• True

• false

The earth is often called the blue planet because of the large amount of water on its surface.

What amount of the earth's water is accessible and drinkable?

• 100%

• 0%

• 70%

• Less than 1%
