• Discharge

Which of the following  causes the deposition of sand at a delta?

• river water slowing as it enters the ocean

What can result when acids in groundwater weather limestone rocks underground?

• Caves can form as the acids dissolve rocks over time.

• Crystals can grow as the water deposits minerals on the rocks.

• Sand formations can build up as the water causes abrasion of the rocks.

• 1. Molten rock can form as the chemical reactions with the acids heat the rocks.

Acid rain wears away the surface of a statue carved from rock. What type of weathering is this? 

• Physical Weathering

• Chemical Weathering

How might the ice cause the crack in the rock to grow?

• by pushing on the sides of the crack

• by being pulled downward by gravity

• by dissolving some of the substances in the rock

• by rubbing against the rock and causing abrasion

 Identify the process that is shown in the diagram above.

• Physical Weathering

• Chemical Weathering

• Erosion

• Deposition
