Rocks

Question 1

What type of rock is made of sediment

Answer 1

sedimentary

Question 2

which type of rock is made from volcanoes?

Answer 2

igneous

Question 3

which type of rock is made from heat and pressure

Answer 3

metamorphic

Question 4

specify the rock cycle

Answer 4

igneous to sediments through weathering and erosion, sediments to sedimentary through compaction and cementation, sedimentary to metamorphic through heat and pressure, metamorphic rock to magma through melting, magma to igneous through crystallization

Question 5

how are crystals formed

Answer 5

when some type of liquid starts cooling down and ultimately creates a solid structure.

Question 6

what is chemical weathering

Answer 6

Chemical weathering involves the interaction of rock with mineral solutions (chemicals) to change the composition of rocks. In this process, water interacts with minerals to create various chemical reactions and transform the rocks.

Question 7

what is physical weathering

Answer 7

physical weathering occurs when physical processes affect the rock, such as changes in temperature or when the rock is exposed to the effects of wind, rain and waves. Water can get into cracks in a rock and, if it freezes, the ice will expand and push the cracks apart.

Question 7

what is biological weathering

Answer 7

Biological weathering is caused by the movements of plants and animals. For example, a rabbit can burrow into a crack in a rock making it bigger and eventually splitting the rock, or a plant may grow in a crack in a rock and, as its roots grow, cause the crack to widen.

Question 8

define weathering

Answer 8

Weathering is the wearing down or breaking of rocks while they are in place.

Question 9

define erosion

Answer 9

Erosion is the geological process in which earthen materials are worn away and transported by natural forces.
