The Sun and Water Cycle Earth and Space 1 What provides the energy needed for evaporation to occur naturally in the water cycle? A Wind B Rivers C Soil D Sun 5.8B

Ocean 2 The labeled diagram shows the water cycle over the ocean. The Sun and Water Cycle Earth and Space 2 The labeled diagram shows the water cycle over the ocean. At which point is salt water being evaporated? A B C D Ocean

What part of the model demonstrates the ocean? The Sun and Water Cycle Earth and Space 3 Students built a model of the water cycle by putting water in the bottom of a plastic bottle and then shining a lamp on it. They observed tiny droplets appearing near the top of the bottle and larger drops sliding down the sides of the bottle. What part of the model demonstrates the ocean? A Lamp shining on bottle. B Tiny droplets forming at top of bottle. C Drops running down the side of bottle. D Water sitting in the bottom of bottle.

This picture shows the water cycle. The Sun and Water Cycle Earth and Space 4 This picture shows the water cycle. Which of the processes is driven by the Sun’s heat? A B C D

The Sun drives the water cycle by doing which of the following? The Sun and Water Cycle Earth and Space 5 The Sun drives the water cycle by doing which of the following? A Rotating on its axis B Giving off light for plants C Keeping the Earth in orbit D Providing heat for evaporation

expose the most water to the Sun’s energy. The Sun and Water Cycle Earth and Space 1 Most evaporation in the water cycle happens from oceans. This is because oceans – A expose the most water to the Sun’s energy. B contain water with salt dissolved in it. C have currents that constantly mix them. D reach the poles where sheets of ice form. 5.8B

Rivers flowing down mountains. The Sun and Water Cycle Earth and Space 2 Sun's heat causes which of the following movements of water in the water cycle? A Rivers flowing down mountains. B Evaporation from oceans. C Precipitation from clouds. D Collection of water in lakes.

The diagram shows the water cycle. The Sun and Water Cycle Earth and Space 3 The diagram shows the water cycle. Which labeled part shows precipitation? A B C D

Where did the most evaporation occur? The Sun and Water Cycle Earth and Space 4 Students are conducting an investigation using four bowls containing water and salt to represent the ocean. Where did the most evaporation occur?
