What happens to a rock when it is weathered quizlet?

As weathering breaks apart rock, the surface area exposed to weathering increases. The total volume of the rock stays the same even though the rock is broken into smaller and smaller pieces.

What rock can occur after a rock is weathered?

5.1 The Unique Properties of Water. Water plays a role in the formation of most sedimentary rock. It is one of the main agents involved in creating the minerals in chemical sedimentary rock. It also is a weathering and erosion agent, producing the grains that become detrital sedimentary rock.

Why do rocks weather quizlet?

The freezing of water that seeps into the cracks of rocks is the process of ice wedging. Ice wedging causes rocks to break apart. Over time, this form of weathering can break down even the hardest rock into soil. The increase in wind, rain, and ice at higher elevations causes the peaks of mountains to weather faster.

What happened to the weathered materials?

Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion.

What is it called when weathered rock is carried away?

erosion. The process of carrying away soil or pieces of rocks; the process through which weathered rock or soil is moved from one place to another.

Why the rocks have weathered so differently?

Rainfall and temperature can affect the rate in which rocks weather. High temperatures and greater rainfall increase the rate of chemical weathering. Minerals in a rock buried in soil will therefore break down more rapidly than minerals in a rock that is exposed to air.

What happens to rocks when they undergo weathering?

These results are due to a process called weathering. Weathering, or the wearing-away of rock by exposure to the elements, not only creates smooth rocks as well as caves and canyons, but it also slowly eats away at other hard objects, including some statues and buildings. Try this process out on a sugar cube and feel how powerful weathering can be.

What happens to a rock when it is weathered?

Although the rocks with rough angles get weathered more quickly, but still a rounded rock will ultimately start weathering and becoming smaller in size. Weathering can not only alter the rock physically, but it can also alter the rounded rock chemically depending on the material by which it is made of.

What are the effects of weathering on rocks?

Weathering Effects Cracking and Breaking. Mechanical weathering physically breaks down rocks because of environmental factors that include heat, cold, water and wind. Altering Mineral Structure. Chemical weathering causes the decomposition, dissolving and loosening of rocks. Changing Chemical Composition. Resistance to Weathering.

What are two ways a rock can be weathered?

The main agents of mechanical weathering are water, wind, ice, and gravity. You will see how each of these works to break rock into smaller pieces. There are two main ways that rocks can break apart into smaller pieces. The way that is most common in cold climates is called ice wedging.
