During physical weathering the elements cause changes in rocks. Water freezes and expands to form linear cracks. This is known as frost wedging. Heat from a fire causes rocks to splinter, and ocean waves batter rocks on the shoreline. Wind carries sand and other small particles that etch patterns on soft rocks.

What occurs during weathering?
Weathering is the process by which rocks and minerals are broken down into smaller pieces through various physical, chemical, or biological means. Physical weathering involves the mechanical breakdown of rocks, while chemical weathering involves the alteration of rock composition through chemical reactions. Biological weathering is the breakdown of rocks by living organisms, such as plant roots or burrowing animals. Over time, these processes can contribute to the formation of soil and shape the Earth's surface.
When is physical weathering most active in New York?
Physical weathering is most active in New York during the winter months when temperatures fluctuate above and below freezing. The freeze-thaw cycle causes rocks and other surfaces to expand and contract, leading to the breakdown of rocks and minerals. Snow and ice can also contribute to physical weathering by exerting pressure as they melt and refreeze.
What occurs during the weathering process?
There are 2 main processes of weathering, mechanical weathering and chemical weathering. In both processes the rocks are broken down. In the mechanical weathering process the rocks are simply made smaller. they are the same composition, just smaller pieces. In the process of chemical weathering the minerals in the rocks undergo a chemical change, they break down. This break down of minerals make them easier to erode. But, erosion is a different question.
What happens during weathering to rocks?
Weathering is the process by which rocks are broken down into smaller pieces through physical or chemical processes. Physical weathering involves the breaking of rocks into smaller pieces through actions such as freeze-thaw cycles or abrasion by wind or water. Chemical weathering involves the alteration of the mineral composition of rocks through processes like oxidation or hydration. Together, physical and chemical weathering contribute to the gradual breakdown of rocks into sediment.
Is decaying plants dissolving minerals in rocks mechanical or chemical?
Decaying plants dissolve minerals in rocks through chemical weathering. As organic acids are released during decomposition, they react with minerals in the rock, causing them to break down chemically. This process contributes to the overall weathering and erosion of the rock over time.

What two chemical constituents cannot form by chemical weathering of the feldspar minerals?
Quartz and clay minerals cannot form by chemical weathering of feldspar minerals. Quartz is already a stable mineral and does not transform during weathering, while clay minerals originate from the breakdown of feldspar.

What happens to a rock's mineral composition during mechanical weathernig?
The minerals that are in a rock will influence how quick it weathers. Strong materials will not weather as quickly as loose materials.

What happens to the minerals in rocks as a result of chemical weathering?
During chemical weathering, minerals in rocks can undergo a process of decomposition and transformation. This occurs as water and atmospheric gases react with the minerals, causing them to dissolve or alter their chemical composition. For example, minerals rich in iron can oxidize and form rust, while silicate minerals can break down and release their constituent elements. Ultimately, this can lead to the formation of new minerals and the release of dissolved ions into water streams.
Is decaying plants dissolving minerals in rocks mechanical or chemical?

Why does the color of granite never change?
The colour of granite does in fact change. For example it will change during the weathering process where feldspar minerals will change to clay minerals such as kaolinite. If the degree of weathering is high this can significantly alter the colour of the granite.
What Rocks break down without changing rock material during what?
Physical weathering!
What happens to a rock's mineral composition during mechanical weathering?
During mechanical weathering, the physical breakdown of rocks occurs without changing their mineral composition. The rock may break into smaller pieces, but the minerals that make up the rock remain the same.
What occurs during the wheathering process?
During the weathering process, rocks and minerals are broken down into smaller pieces through mechanical or chemical means. Mechanical weathering involves physical forces like wind, water, and ice breaking rocks apart, while chemical weathering involves the breakdown of minerals due to chemical reactions with water, oxygen, or acids. Together, these processes contribute to the transformation of rocks into sediment and soil over time.
