A warm front is progressing northward ahead of the storm center while a cold front is sweeping southeastward. The cool air mass north of the warm front is already in place. As the storm intensifies, the cold front rotates around the storm and catches the warm front. Identify the weather map that shows these conditions.

Energy from the sun is transferred to the earth by

• conduction.

• conservation.

• convection.

• radiation.

The numbers 1-4 represent large bodies of water in the United States. All of these are freshwater and are flowing, which means they are moving and do not stay still. They empty into a larger body of water, such as an ocean. What are these bodies of water called?

• glaciers

• lakes

• rivers

• seas

The image is a model showing the processes of the water cycle. Water uptake to the atmosphere occurs through the processes of evaporation and transpiration from plants where it condenses to form clouds. Clouds release the water through precipitation. During an extreme rainy season, what can we expect to happen to the surface ground water stored in ponds and lakes?

• animals drink more water, so water levels decrease

• water levels will increase because there is more precipitation

• water levels will increase because there is more evaporation and transpiration

• water levels will decrease because there is more evaporation and transpiration

Describe the role of temperature change in cloud formation.

• As water on Earth cools down, it condenses in the air and forms clouds.

• As water on Earth cools down, it evaporates into the atmosphere and forms clouds.

• Water on Earth heats up and evaporates into the atmosphere, then cools and condenses to form clouds.

• Water on Earth heats up and evaporates into the atmosphere. Water vapor continues to heat up to form clouds.
