• F Heat from the sun warms the ocean, causing water to evaporate. The water vapor then condenses to form a cumulonimbus cloud.

• G Heat from the sun causes clouds in the area to gather over the ocean and form one large cumulonimbus cloud.

• G Heat from the sun causes clouds in the area togather over the ocean and form one large cumulonimbus cloud.

• J Light from the sun causes ocean water to reflect water vapor into the air and gather over the ocean into a cumulonimbus cloud.

Which statement best describes the processes of weathering and erosion?

• F Weathering and erosion are directly responsible for the breakdown of any type ofrock into smaller particles and the carrying away of the loose sediments.
