What must occur before clouds can form?

• water vapor must get warmer

• water vapor must lose heat energy

• precipitation must begin to fall and run off

• transpiration must add water vapor to the atmosphere

Which fact best explains why MOST evaporation happens in the oceans?

• ocean water is salty

• there are mountain ranges on the ocean floor

• about 97 percent of Earth's water is ocean water

• fewer clouds block sunlight over the ocean

Camilla put water in two flat, uncovered pans. She placed one pan in a sunny spot and put the other pan in a shady spot. She left the pans for 12 hours, then returned and measured the water in both pans. What MOST likely happened to the water in the pans?

• more water evaporated from the pan exposed to sunshine

• more water evaporated from the pan left in the shade

• the same amount of water evaporated from both pans

• no water evaporated from either pan

Solar radiation has a part in the water cycle by

• affecting ocean tides

• changing liquid water to vapor

• determining the types of clouds formed

• helping in the absorption of groundwater

A student states the weather is the same as the climate. Which response BEST tells the student the difference between weather and climate?

• Weather is about the wind and the rain, but climate is about the clouds.

• Weather is the conditions in one day, but climate is the conditions over a long time.

• Weather is measured with tools like thermometers, but climate is measured with tools like forecasts.

• Weather is recorded on charts, but climate is recorded on world maps.

Land heats up faster during the day than water does. As the beach gets warm during the day, it heats the air above it. The warm air rises and cool air from the ocean is pulled in to replace it. So, air flows from the ocean to the land. At night, the land cools faster than the ocean. What MOST likely happens to the air at the beach at night?

• the air is still

• the air moves along the coast

• the air flows from the ocean to the land

• the air flows from the land to the ocean
