Earth Science - Chapter 14 Weathering and Erosion

A physical feature of Earth's surface

The process by which rock is broken down becasue of chemical interactions

The process by which water flows over a layer of soil and removes the topsoil

Sand particles have diameters of about

If a chemical is rich in H+ ions, it is said to be

A cross section of the soil and its bedrock

Thick tropical soils are called

The process by which elements combine with oxygen

The type of soil depends mainly on the soil's

The conversion of minerals into a carbonate

The process by which rock is broken down into smaller pieces by physical means

Soil that forms and stays directly over its parent rock is called

When an acid combines with the water in the atmosphere, it produces

Clay particles have a diameter of less than -------- mm.

Common agents of mechanical weathering include all of the following except

The slow, downslope flow of soil saturated with water in areas surrounding glaciers

The different layers of soil are called

Climate does NOT affect the rate at which rocks weather.

The elevation and slope of the land surface

The more exposure to weathering agents the rock receives, the faster it will weather.

The collision of rocks that results in the breaking and wearing away of rocks is called

The change in the composition of minerals when they react chemically with water

THe process by which softer rock wears away and leaves harder rock behind

Silt particles have a diameter of about

What is not a type of temerpate soil

When water seeps in cracks of rocks and then freezes, this type of mechanical weathering occurs

The movement of a large mass of sediement or a section of land down a slope

The physical breakdown or chemical decomposition of rock materials is called

When water breaks down, it produces

The process by which the products of weathering are transported

Soil that results from the deposition of rock material that has been carried away is called

If a chemical is rich in OH- ions, it is said to be

The part of the rock that is exposed to air, water, and other agents of weathering

Plants and animals are important agents of mechanical weathering.

Which of the following is not a way of reducing erosion

Dark organic material

What is not one of  the three types of soils, based on climate

Water can carry dissolved minerals to lower layers. This process is known as

A complex mixture of minerals, water, gases, and remains of organisms
