Unit 4 - Topic 2 Erosion and Deposition

What change will a pebble usually undergo when it is transported a great distance by streams?

• It will become jagged and its mass will decrease

• It will become jagged and its volume will increase

• It will become rounded and its mass will increase

• It will become rounded and its volume will decrease

Why do particles carried by a river settle to the bottom as the river enters the ocean?

• The density of the ocean water is greater than the density of the river water.

• The kinetic energy of the particles increases as the particles enter the ocean.

• The velocity of the river water decreases as it enters the ocean.

• The large particles have a greater surface area than the small particles.

The velocity of a stream is decreasing. As the velocity approaches zero, which size particle will most likely remain in suspension?

• pebble

• sand

• clay

• boulder

Small spheres that are identical in shape and size are composed of one of four different kinds of substances: A, B, C, or D. The spheres are mixed together and poured into a clear plastic tube filled with water. Which property of the spheres caused them to settle in the tube as shown in the diagram?

• their shape

• their size

• their density

• their hardness

Base your answer on the diagram ad your knowledge of Earth Science. All three sediments in the diagram are placed in the cylinder with water, the mixture is shaken, and the particles are allowed to settle. Which diagram best represents the order in which the particles settled?
