ES Hmwk; Weathering

What is the main difference between chemical & physical weathering?

• chemical weathering alters the composition of minerals, and physical weathering does not.

• chemical weathering increases surface area of minerals, & physical weathering does not.

• physical weathering alters the composition of minerals, and chemical weathering does not.

• physical weathering increases the surface area of minerals, & chemical weathering does not.

Which is an example of physical weathering?

• the cracking of rock caused by the freezing & thawing of water

• the transportation of sediment in a stream

• the reaction of limestone with acid rainwater

• the formation of a sandbar along the side of a stream

Water is a major agent of chemical weathering because water

• cools the surroundings when it evaporates

• dissolves many of the minerals that make up rocks

• has a density of oone gram per cubic centimeter

• has the higheest specific heat of all common earth materials

• cold & dry

• cold & humid

• warm & dry

• warm & humid

What is the relationship between the depth of a soil formed from underlying bedrock & the length of the weathering period responsible for its formation?

A variety of soil types are found in New York

State primarily because areas of the state differ in their

• amounts of insolation

• distances from ocean

• underlying bedrock and sediments

• amounts of human activities

Describe the specific temperature and moisture characteristics of a climate in which frost action is tdominant in the winter season.

The chemical compostion of soil formed in a certain area from the bedrock beneath it is determined by

• method by which the soil was transported to the area

• slope of the land and the particle size of the soil

• length of time since the last crustal movement in the area occured

• minerals in the bedrock beneath the soil and the climate in the area

Which type of climate has the greatest amount of rock weathering caused by frost action?

• a wet climate in which temperatures remain below freezing

• a wet climate in which temperatures alternate below freezing and above freezing

• a dry climate in which temperatures remain below freezing

• a dry climate in which temperatures alternate between below freezing and above freezing

NYS soils are most likely composed of rock particles that have been

• weathered from the underlying bedrock

• weathered from the bedrock in Northern Pennsylvania

• transported by glacier water

• transported by wind
