Dissolution occurs when _____. a. minerals are turned into rust b. minerals are removed by frost c. minerals absorb water and expand d. minerals are dissolved into water Why does physical weathering speed up the processes of chemical weathering? a. Chemical weathering requires salt, which is provided by salt wedging. b. Chemical weathering can occur only on small surfaces, not large ones. c. Physical weathering requires abundant water, as does chemical weathering. d. Physical weathering produces fresh surfaces for chemical weathering to attack Which of the following does NOT affect soil thickness? a. vegetation type b. climate c. types of animals d. timeExplanation / Answer
1)Minerals are dissolved into water
Dissolution usually occurs as minerals are dissolved through time. Most minerals will be dissolved by water. The water will tend to break down the mineral into fine grains. The grains of the mineral become visible on the surface of gravestones. The surface will tend to have a "sugary" feeling. This will cause the corners of gravestones to become rounded. The lettering tends to become less distinct.
2)b.chemical weathering occur only on small surfaces, not large ones
Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Water, ice, acids, salt, plants, animals, and changes in temperature are all agents of weathering.Mechanical weathering, also called physical weathering, causes rocks to crumble. Water seeps into cracks and crevices in the rock. If the temperature drops low enough, the water will freeze. When water freezes, it expands. The ice then works as a wedge. It slowly widens the cracks and splits the rock. When ice melts, water performs the act of erosion by carrying away the tiny rock fragments lost in the split.
3)c.types of animals
