What is mechanical weathering?
Is the physical breakdown of an object into smaller components without changing its chemical composition.
100
How is weathering different from erosion?
Weathering is the breaking down of rocks into smaller pieces called sediments. Erosion is the movement of these sediments by water, ice, wind, or gravity to a new location.

What is deposition?
is the geological process in which sediments, soil and rocks are added to a land form or land mass.
The Drop Of Sediment.

What is Chemical Weathering.?
Refers to the breakdown of an object into particles.

What is chemical Weathering?
Refers to the breakdown of an object into particles with a different mineral composition than the original object.

How is mechanical weathering different from chemical weathering?
Mechanical weathering physically breaks rocks into smaller pieces. Chemical weathering changes the surface of rocks into new substances, such as rust.
200
What do wind erosion and deposition form?
Sand dunes.
200
Where does deposition takes places?
Deposition takes place when materials are dropped.
200
What is a glacier.?
Glacier is a persistent body of dense ice that is constantly moving under its own weight it forms where the accumulation of snow exceeds its ablation over many years, often centuries.
300
What type of chemical weathering creates caves or caverns?
Acids in groundwater.
300
What type of climate causes mechanical weathering to happen at a greater rate?
Cold and wet.
300
How does waves shape the coast?
Through erosion, by breaking down rock and moving sand and other sediment.
300
What causes deposition?
Deposition can cause a lot of things such as dunes, hills, mounds, etc.
300
What is Groundwater.?
Groundwater is the water present beneath Earth's surface in soil pore spaces and in the fractures of rock formations.
400
What type of climate does chemical weathering happen faster?
Humid and warm.
400
How is mechanical weathering formed?
Mechanical weathering results from changes in temperature and pressure surrounding rocks. The expansion or contraction of air and pressure creates fractures in rock surfaces, ultimately making rocks break into smaller pieces.
400
What is Erosion?
Erosion is the removal of rock particles from a location.
400
Where deposition occur?
Deposition occurs when the sea loses energy and drops any matter that it may be carrying.
400
What is Ice Wedging.?
Ice wedging is a form of mechanical weathering or physical weathering in which cracks in rock or other surfaces fill with water, freeze and expand, causing the cracks to enlarge and eventually break.
500
How is chemical weathering formed?
Chemical weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts.
500
Where does mechanical weathering takes places?
Mechanical weathering takes place when rocks are broken down without any change in the chemical nature of the rocks.
500
How is Erosion caused?
Is Caused by water, wind, ice, or gravity.
500
What is the name of the process where deposition takes place?
Usually occurs at the mouth of a stream a process called horizontal sorting.

What is Limestone.?
Is a hard sedimentary rock, composed mainly of calcium carbonate or dolomite, used as building material and in the making of cement.
