What are the 6 agents of physical weathering?
The six agents of physical weathering are temperature changes, water, ice, salt crystal growth, wind, and living organisms. These agents break down rocks and minerals into smaller pieces through processes like freezing and thawing, abrasion, and root wedging.
What does physical weathering involve?
Physical weathering involves the breakdown of rocks and minerals through mechanical processes like freezing and thawing, abrasion from wind and water, or plant root growth. These processes can cause rocks to break into smaller pieces without changing their composition.
What are 6 types of mechanical weathering?
Frost wedging: The repeated freezing and thawing of water in cracks in rocks. Salt crystal growth: Salt crystals form in the cracks of rocks and exert pressure as they expand. Exfoliation: Outer layers of rocks peel off due to pressure release. Thermal expansion and contraction: Rocks expand and contract due to changes in temperature, causing stress. Biological activity: Roots and burrowing animals can break apart rocks. Abrasion: Rocks are worn down by friction from wind, water, or rubbing against other rocks.
What are the stages of biological weathering?
1. There is a crack made in a rock as an animal has loosened it. 2. A seed is dropped by a bird into the crack. 3. The crack has been widened. 4. Then as time goes by the seed will grow and grow. 5. As it is growing the roots will be putting pressure on the rock pushing through it. 6. Eventually a tree or bush or something will have grown through the rock breaking it up.
What is repeated thawing and freezing of water in cracks of rocks?
Yes, freezing and thawing does cause these things. This is known as freeze-thaw weathering. For an in depth description of the process:Water falls into a slight crack in a rock, or a bedding plane between rock strataOvernight the water freezes and expandsThe crack is forced to expand as the ice expanding is more powerful than the capability of the rock to resist stress.Over a number of nights the process is repeated.Eventually when the crack is great enough, a/some fragment/s or rock strata come loose and fall down the slope due to gravity.They fall down the slope, forming a scree slope/fanFor a road surface, apply the word 'road' in place of rock and remove advanced terms completely. Eliminate the second part of step 5 and the whole of step 6.**N.B.Not all cracks are formed by freeze-thaw weathering.

A geologist has 10 rocks of equal weight If 6 rocks and a 10-ounce weight balance on a scale with 4 rocks and a 22-ounce weight what is the weight in ounces of one of these rocks?
6 ounces
A detail study of different types of soils in India?
The types of soil found in India are as follows: 1. Alluvial soil (formed by residual alluvial formed by rivers.) 2. Red soil (formed by weathering of metamorphic rocks.) 3. Laterite (due to weathering of laterite rocks.) 4. Black soil (volcanic origin,lava soil due to disintegration of basalt.) 5. Sandy soil (due to deposit of sand.) 6. Clayey soil (due to mud and clay.)

What is the name of the destructive force that breaks down rock?
Weathering and or erosion: Earthquakes cause rockfalls. Water freezing and expanding in cracks causes rocks to break. Wind and water erodes rock by passing over the rock and blowing or washing away the surface of the rock and/or by causing the rock to roll or tumble along the ground or against other rocks wearing or grinding the rock away.
