Antartica is a very cold place. Because chemical activities are very slow under low temperature hence chemical weathering is also not much.
1) Chemical and biological sedimentary rocks are produced by chemical weathering instead of the siliciclastic sediments which are created by physical weathering. Because physical weathering is much more often than the chemical weathering there are 10 times more clastic sediments in the earth's crust than chemical and biological sediments.
Physical weathering breaks rock down into much smaller pieces and gives the original rock a much greater surface area which, when exposed to chemical agents such as carbonic acid, reacts at a much faster rate than it would had the larger rock not undergone physical weathering.
It is mechanical as pressure is very much a mechanical element.
Physical weathering is when some liquid like wind or water over a long period of time breaks of the outer layers of and object, like a rock. Chemical weathering is when an acid or something else chemically eats away at an object like a rock, happening at a much faster rate. Physically weathering - water eroding a rock Chemical weathering - coca cola acids eating away at the rust of a nail. Hopefully this helped
== == First off deposition is the last step out of Erosion, Weathering and itself. Chemical weathering causes the erosional effects of glaciers which also incude deposition. An example is that soil in the nothern parts of the United States are deposited of material once carried by a glacier, which pretty much starts the whole process over again. Beginning with Chemical Weathering and ending with Deposition.
Yes because chemical weathering occurs faster in desert climates. Rocks are us to chemical weathering and temperate climates get it but not as much.
It has the highest rate of chemical weathering because chemical weathering occurs much faster in hot, humid climates. This makes rain forests a target for chemical weathering, and in hot seasons, the weathering skyrockets.

Chemical reactions break down the bonds holding the rocks together, causing them to fall apart, forming smaller and smaller pieces. Chemical weathering is much more common in locations where there is a lot of water. This is because water is important to many of the chemical reactions that can take place. Warmer temperatures are also more friendly to chemical weathering.

another gas found in air, carbon dioxide, also causes chemical, weathering. Carbon dioxide dissolves in rainwater and in water that sinks through air pockets in the soil. The result is a weak acid called carbonic acid. Carbonic acid easily weathers rocks such as marble and limestone.

Chemical weathering is much more common in locations where there is a lot of water. This is because water is important to many of the chemical reactions that can take place. Warmer temperatures are also more friendly to chemical weathering. The most common types of chemical weathering are oxidation, hydrolysis and carbonation.
Weathering can wear down rock over time, smoothing out rough rock formations. Since harder rocks are much more resistant to weathering than softer ones, weathering can change the shape of a rock formation as the soft rock is weathered away, leaving behind the hard rock in a potentially very different shape. Erosion has a very small effect, but could slightly change the shape as dirt and rock particles on the formations are blown or washed away.
