G6U1 Chapter 2

the Sun shines down through the atmosphere of invisible gases to Earth’s surface

the Earth warms

some of the thermal energy (heat) radiates back toward space—some escapes

some is trapped by special gases in the atmosphere that absorb thermal energy

these gases are called greenhouse gases because they act like the glass on a greenhouse to trap thermal energy.

As the Earth’s bodies of water absorb more thermal energy, the temperature of the water increases.

This increases the rate of evaporation and results in more water vapor in the atmosphere.

As the water vapor rises in the atmosphere, it cools and condenses to form clouds and, ultimately, precipitation.

corals become stressed when ocean water temperatures increase

corals eject the algae that live in them

when corals lose their algae, they lose their food source

 (inside Earth & on the surface)

– an event that occurs in nature, both here on Earth and throughout the universe

– something done by humans

– a cycle the Sun goes through about every 11 years. It affects the activity on the Sun’s surface.

– changes in land use

– a large-scale climate effect due to periodic warming of ocean surface temperatures
