• 1. The seashell was deposited into the rock by a human being.

A group of scientists are studying the effects of rainfall on the Zambezi River in Africa. They measure the amount of rainfall each year. They also measure the amount of sediment, or broken down rock material, carried by the river each year. They examine the data that they have collected to look for patterns. They also collect aerial photos of the river, like the one you see here. The green and brown parts of the photo show the land around the river. The blue parts of the photo show water. The lighter blue is where the water is shallow. The darker blue is where the water is deep.

Observe the photo of the river. How was the circled area of the river formed?

• 1. It was formed by waves in the ocean.

• 1. It was formed by sand from the beach.

• 1. It was formed by deposition by the river.

• 1. It was formed by rainfall stirring up the sand.

Scientists measured an increase in rainfall one year. What was the most likely effect on the circled area?

• 1. Less weathering occurred.

• 1. More sediment entered the river.

• 1. The area did not have as much erosion.

• 1. A decrease in organisms living in the river.
