My Explanation About The Cause Of Rock Breaking
What is biological weathering? Made SIMPLE
Biological weathering works in different ways. For instance, plant roots can grow into cracks in rocks and as they expand, they break the rock apart. Animals, especially those that burrow, break apart rocks and soil, moving and mixing it up. Microorganisms like bacteria, fungi, and lichens can produce chemicals that dissolve rocks.

Exfoliation as a Phase of Rock Weathering
subjected sound igneous rocks to sudden changes of temperature from 150 to 2100 C. by plunging the cold rock into boiling oil. In no case did this cause any spalling or cracking or even a visible weaken- ing of the rock. Inasmuch as these laboratory changes were much greater than any possible temperature range in the desert (600-

The rock cycle
The Earth is an active planet. Earthquakes shake and volcanoes erupt. Sections of the crust are on the move. Mountains push up and wear down. These and many other processes contribute to the rock cycle, which makes and changes rocks on or below the Earth's surface. The Earth is 4.6 billion years old, but you won't find rocks that old because they have been recycled into …

Rocks: Rocks are large structures that are made of minerals. They can be formed by the compression of sediments above the earths surface, volcanic activity or the action of heat and pressure below the earth's surface.

Biological Weathering Definition, Process, Types & Examples
Depending on how rocks and rock particles are broken down, biological weathering is of two types: by physical means or by chemicals and organic compounds. Biological Weathering By Physical Means. This type of weathering occurs when a force or pressure is applied to break rocks apart or degrade the minerals in them.

5.1: Mechanical Weathering
When a mass of rock is exposed by weathering and removal of the overlying rock, there is a decrease in the confining pressure on the rock, and the rock expands. This unloading promotes cracking of the rock, known as exfoliation, as shown in the granitic rock in Figure (PageIndex{1})., which, in places, is peeling off like the layers of an onion.

Coastal Erosion Processes Flashcards
This leads to an irregular coastline as the different rocks will be eroded at different speeds by the incoming waves. Harder rock is more resistant, erodes slowly and forms headlands protruding into the sea. Softer rock is less resistant, erodes quicker and forms bays Differential Erosion has produced a coastline of alternating headlands and bays

Which term describes weathering? breaks down rock causes …
The term that describes weathering is 'breaks down rock'. Weathering is the process of rocks being broken down into smaller pieces through physical and chemical processes. It does not cause heating and cooling, but can lead to the formation of larger rocks and pebbles. Explanation: The term that describes weathering is breaks down rock ...

4 Types and Examples of Chemical Weathering
As roots expand into rock, acids can change the minerals in the rock. Plant roots also use carbon dioxide, thus changing the chemistry of soil. New, weaker minerals are often more brittle; this makes it easier for plant roots to break up rock. Once the rock is broken up, water can get into the cracks and oxidize or freeze.

6.2: Weathering and Erosion
The sudden pressure drop causes the rock to rapidly expand and crack; this is called pressure expansion. Sheeting or exfoliation is when the rock surface spalls off in layers. Spheroidal weathering is a type of exfoliation that produces rounded features and is caused when chemical weathering moves along joints in the bedrock.

2.2
Salt crystal growth can cause the break-up of rock materials. Crystal growth often occurs when groundwater moves into empty pores or spaces of rock by capillary action. As the water evaporates, salt crystals grow and accumulate, putting pressure on the rock and causing it to break apart. Salt crystallization is common in drier climates.

5: Weathering, Erosion, and Sedimentary Rocks
5.3: Sedimentary Rocks Sedimentary rock is classified into two main categories: clastic and chemical. Clastic or detrital sedimentary rocks are made from pieces of bedrock, sediment, derived primarily by mechanical weathering. Clastic rocks may also include chemically weathered sediment. They are classified by grain shape, grain size, and sorting.
