Weather and Precipitation

Lily made a model to help demonstrate how water moves in global ocean currents. She mixed water with blue food coloring. Then she froze that water, making ice. She filled a fish tank with warm water. Lily placed the blue ice cube into the tank of warm water. In which direction will the colored water moves as the ice cube melts.

• To the top

• To the right

• To the left

• To the bottom

A group of students collected data about wind speed, wind direction, humidity, and temperature. They wanted to know what would happen when they saw fog. In which situation will they see fog over the ocean?

• warm, humid air from land cooling as it moves over cold ocean water

• cold, humid air from land warming as it moves over warm ocean water

• cold, dry air warming and becoming more humid as it moves over warm ocean water

The sun heats Earth differently at different latitudes. How does this affect climate at different latitudes?

• The sun heats all of Earth so climates are similar throughout the globe.

• The sun heats Earth’s atmosphere and oceans, causing all of the warm air to concentrate at the equator.

• The uneven heating of Earth by the sun causes the climate to be warm and dry at the equator and cold and wet toward the poles.

• The angle of sunlight is different at different latitudes, which causes the climate to be warm at the equator and colder toward the poles.
