Define Deposition:
The buildup of land by the settlement of sediment and soil in a new location
OR

A student investigates erosion using four kinds of earth material: topsoil, clay, sand, and soil
planted with grass. The setup for the investigation is shown below.
Water is separated from the Earth materials with a filter. The pictures below show the amounts of Earth materials that were collected.
The results of this investigation best support which conclusion:
Topsoil is easily eroded. OR Sand has a coarse texture.
Topsoil is easily eroded.

Sandstone arches, like the one shown in the picture below, form in some desert environments.
Which of the following most likely occurred to form this arch?
the cooling of lava
OR
the blowing of wind
the blowing of wind

Define Weathering:
The breakdown of rocks into very small particles by gravity, water, wind, and ice
OR
A low area between higher areas of elevation
The breakdown of rocks into very small particles by gravity, water, wind, and ice

A student hiking in a rocky area on a mountain notices that wide, deep cracks have formed in some of the large rocks. Some of the cracks are so large that the rocks have broken apart. Which process most likely caused these rocks to crack and break?
erosion by wind
OR
water freezing and thawing
water freezing and thawing
