What is global warming?

• the melting of ice caps and glaciers

• the increasing heat of Earth's asthenosphere

• the increasing temperature of Earth's atmosphere

• the decrease of oxygen level in the Earth's atmosphere

What is greenhouse effect?

• warm atmosphere around Earth caused by trapped sun's radiation

• absorbs and emits radiant energy from the sun

• increased carbon in the Earth's atmosphere

• increasing Earth's temperature

How urbanization affect an area?

• increase the risk of flooding in an area

• decreases the need of natural resources

Which strategy reduces the amount of carbon dioxide generated by power plants?

• removing sulfur from coal

• stop generating electricity

• capture carbon dioxide emission

• reduce the amount of natural gas in generating energy

How agriculture can negatively impact the environment?

• It releases CO2 into the atmosphere.

• It can increase the amount of flooding.

• Farmers use fertilizers which contaminate rivers and streams.

• Agriculture reduces the amount of oxygen in the atmosphere.

What natural resource is commonly obtained by surface mining?

• oil

• coal

• wood
