Earth Science Review

Describe the process of condensation in the water cycle.

• Condensation is the process by which water vapor cools and changes back into liquid water, forming clouds.

• Condensation occurs when liquid water evaporates into vapor in the atmosphere.

• Condensation is the process of water being absorbed by plants from the soil.

• Condensation happens when clouds release precipitation back to the earth.

What is the difference between surface currents and deep ocean currents?

• Surface currents are found at or near the ocean's surface and are primarily driven by wind.

• Deep ocean currents are found at the surface and are driven by wind.

• Surface currents are driven by water density and temperature differences.

• Deep ocean currents are primarily influenced by the moon's gravitational pull.

What role does the Sun play in the water cycle?

• The Sun cools the water, preventing evaporation.

• The Sun provides the energy necessary for evaporation and transpiration, making it essential for the water cycle to occur.

• The Sun absorbs all the water in the cycle, preventing it from evaporating.

• The Sun creates clouds that block evaporation.

How do ocean currents impact marine life?

• They have no effect on marine life.

• They influence nutrient distribution, migration patterns, and the overall health of marine ecosystems.

• They only affect the temperature of the water.

• They are primarily responsible for ocean pollution.

What is the role of density in ocean currents?

• Density has no effect on ocean currents.

• Denser water sinks, creating deep currents, while less dense water rises, influencing the movement of water in the ocean.

• Density only affects surface currents, not deep currents.

• Density is only important in freshwater systems, not in oceans.

What is the water cycle?

• The process by which water is stored in lakes and rivers.

• The continuous process by which water moves through the environment, including evaporation, condensation, precipitation, and runoff.

• A method of purifying water through filtration.

• The cycle of water used in irrigation systems.

What is the significance of ocean currents?

• They are responsible for the formation of ocean waves.

• They play a crucial role in regulating climate, distributing heat, and influencing weather patterns around the globe.

• They only affect marine life and have no impact on weather.

• They are primarily caused by the gravitational pull of the moon.

What factors can disrupt the water cycle?

• Climate change, deforestation, and pollution

• Increased rainfall and snowmelt

• Urbanization and population growth

• Natural disasters like earthquakes and volcanoes

Define evaporation in the context of the water cycle.

• Evaporation is the process by which water changes from a liquid to a gas, primarily due to heat from the Sun.

• Evaporation is the process of water moving from the ground into the atmosphere as a result of wind.

• Evaporation is the transformation of water vapor into liquid water when temperatures drop.

• Evaporation is the process of water being absorbed by plants and released into the atmosphere.

During which stage of the water cycle does water flow back towards the sea as runoff?

• Evaporation stage

• Condensation stage

• Runoff stage

• Precipitation stage
