Rising sea levels are caused by melting ICE SHEETS, which are

• glaciers covering over 19,000 square miles.

• layers of ice crystals beneath the oceans.

• a type of chemicals used in factories.

• used to make ice in refrigerators.

When sunlight hits sea ice,

• it can harm the eyes of astronauts.

• it travels back to the moon making it brighter.

• it is reflected and energy is sent back into space.

• it causes blindness in polar bears.

Climate changes in the past were not a cause of worry because

• the Earth was getting ready for humans.

• the climate changed slowly.

• there weren't too many towns by the sea.

• population was low.

Scientists try to find out about extreme temperatures by studying HEAT WAVES, which is...

• a period of five days or more when the sun doesn’t set.

• a period when people don’t eat ice cream outside.

• a period when no clouds can be seen in the sky.

• a period when the temperature is very hot for several days.

Though both hurricanes and typhoons are spinning storms, their names depend on

• what time of the year they occur in.

Seawater expands and sea levels rise when the sea

• cools down.

• is filled with salt.

• is heated.

• doesn’t evaporate.

Climate changes will likely make _____ drier.

• the atmosphere in the moon

• the Earth's oceans
