Rock Cycle

Question 1

There are 3 types of rocks

Answer 1

Igneous rocks: These are rocks that are formed by the cooling and solidification of molten material, such as lava or magma. Igneous rocks can be either intrusive (formed beneath the Earth’s surface) or extrusive (formed on the Earth’s surface). Examples of igneous rocks include granite, basalt, and pumice.
Sedimentary rocks: These are rocks that are formed by the deposition, compaction, and cementation of sediment, which can include fragments of other rocks, organic matter, or minerals. Sedimentary rocks can be further classified into three types: clastic (formed from fragments of other rocks), chemical (formed from the precipitation of minerals from water), and organic (formed from the accumulation of organic matter). Examples of sedimentary rocks include sandstone, limestone, and shale.
Metamorphic rocks: These are rocks that are formed by the alteration of pre-existing rocks due to changes in temperature, pressure, or chemical environment. Metamorphic rocks can be foliated (with a layered appearance due to the alignment of minerals) or non-foliated. Examples of metamorphic rocks include marble, slate, and gneiss.

Question 2

Weathering, erosion and deposiiton

Answer 2

Weathering:
Physical - rain, heating and cooling, wind, ice,
gravity

Chemical - acid rain, urine

Biological - mosses and lichens, animal feet, tree
roots

Weathering breaks down the rock
Erosion moves the broken pieces along
depositon is where the broken pieces ed=nd up

Question 3

How do sediment rock form

Answer 3

Weathering, erosion, depositon, compaction, cementation

Compaction: Particles squeened together under great pressure
Cementation: particles are glued together as mineral solutions harden

Question 4

Metamorphic rocks

Answer 4

Metamorphic:
Metamorphic rocks form when other types of rock change into new ones
They form deep underground
Metamorphic rocks require a lot of time, heat and pressure to form

Question 5

igneous rocks defintion + different types

Answer 5

Igenous:
Igneous rocks are made from molten from from deep underground
Magma that cools underground are called intrusive rocks
Magam that cools above ground is called extrusve rocks

Question 6

Fossil formation in sedimentary rock

Answer 6

1) Fossil formation in sedimentary rock
Organism Dies
2) Water moves sediment to cover dead organizam
3)More and more layers cover the organsim under there is enough pressure tot run it to the lowest layer
4) Erosion starts to wear away upper layers of soil and rock
5) More erosion (or digginign by humans) occurs unitl fossils is exposed

Question 7

The two major sources of energy for the rock cycle

Answer 7

The two major sources of energy for the rock cycle are also shown; the sun provides energy for surface processes such as weathering, erosion, and transport, and the Earth’s internal heat provides energy for processes like subduction, melting, and metamorphism.
