What happens to the temperature if more greenhouse gases are released into the atmosphere?

• Temperature goes up
• Temperature goes down

Which of the following does NOT happen to solar energy when it reaches Earth?

• Some solar energy reflects off the atmosphere, back to space

• Some solar energy passes through Earth and comes out the other side

• Some solar energy is absorbed by land and water

• Some solar energy is radiated from the Earth's surface and trapped by the atmosphere

What is the greenhouse effect?

• The warming of a planet due to trapped radiation.
• The cooling of Earth due to air pollution.
• The heating of a solid, such as a rock.

The greenhouse effect is a natural process

• true

• false

The greenhouse effect is caused by

• more heat arriving at the Earth from the sun

• the Earth releasing more heat at night

• gases in the air trapping heat released by the Earth

Melting of glaciers and polar ice caps....

• will result in cooler temperatures in the Arctic
• will result in sea-levels rising
• Will have no effect on ecosystems
• None of the above

What is an increase in global temperatures believed to be caused in part by the greenhouse effect.

• Climate

• Global Warming

• Climate Change

• Greenhouse Effect

The greenhouse effect is about

• warming the atmosphere because of increased CO₂ levels

• warming the atmosphere because of decreased CO_{2 }levels

• cooing the atmosphere because of increased CO_{2 }levels

• cooling the atmosphere because of decreased CO_{2 }levels

The tropical rain forest & tropical savanna biomes are similar in ___________, but ________________________________.

• temperature / the savannah doesn't receive enough rainfall to be a forest
• precipitation / the rain forest is hotter
• precipitation / the savanna is cooler
• temperature / the rain forest doesn't receive enough sunlight to be a savanna
