• 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.

• A Stir the liquids, let them settle, and then identify the bottom layer as water

• B Drop a piece of ice into the graduated cylinder, let the ice settle, and then identify the layer just above the ice as water

• C Add water to the graduated cylinder, let the mixture settle, and then identify the layer that increases in volume as water

• D Carefully pour each layer into separate plastic containers, place the containers in a freezer, and then identify the liquid that takes the longest to freeze as water

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.

• G Weathering and erosion are directly responsible for depositing loose sediments on the bottom of the ocean, forming layers of sediment.

• H Weathering and erosion are directly responsible for the amount of water in a river that transports sediments to the sea.

• J Weathering and erosion are directly responsible for the transportation, deposition, and compaction of loose sediments on the seafloor.

Based on their properties, which of the objects is most likely a metal?

• A Object , because it is a solid that is less dense than water

• B Object 2, because all metals float in water

• C Object 2, because metals conduct thermal energy and electricity

• D Object1, because it can be used to provide insulation for thermal energy
