How does the ocean affect weather on Earth?

• Waves in the ocean push on the air above, which causes storms to form.
• Salt in the ocean dries the air above, causing the air to heat up and rise.
• Water evaporates from the ocean, causing clouds to form and send rain back to Earth.
• Water in the ocean is cooler than the air above, which causes the air temperature to remain low.

Which relationship results in the highest level of evaporation from Earth’s water reservoirs?

• greatest surface area and most direct sunlight
• greatest surface area and least direct sunlight
• least surface area and most direct sunlight
• least surface area and least direct sunlight

Energy from the Sun causes evaporation. Why does more evaporation happen from the oceans than from fresh-water sources?

• Oceans have a greater surface area.
• Salt water evaporates faster than freshwater.
• The air over oceans can hold more water vapor.
• Oceans touch more landmasses than freshwater sources.

Which important feature of the water cycle is missing from this figure?

• the moon
• the sun
• the rainbow
• the people

Water vapor sometimes condenses into stratus clouds that are in contact with the ground. What forms as a result of this process?

• ozone
• methane
• fog
• smoke

Two characteristics of the Nevada climate are low humidity and abundant sunshine. This combination of characteristics most likely results in

• low altitude fog.
• rapid evaporation.
• high elevation snowfall.
• frequent thunderstorms.

Which statement explains what will most likely happen to the hydrosphere in an area where air temperatures increase?

• Earthquake intensity will decrease.
• Rock weathering will increase.
• Mountain formation will decrease.
• Evaporation will increase.

A map of the weather in Texas is shown below.

Which stage of the water cycle most directly creates an area of warm, moist air?

• condensation
• evaporation
• precipitation
• transpiration

During evaporation, the Sun transfers energy to water.
During which steps is energy released from the water?

• 1, 2, 3
• 2, 3, 4
• 3, 4, 1
• 4, 1, 2

Which two things interact most in the water cycle?

• oceans and the Moon
• oceans and the Sun
• lakes and the Moon
• lakes and the Sun
