Rock Cycle, Soil Formation, GroundWater

Question 1

What is Magma And what role does it have in the rock cycle?

Answer 1

Melted rock deep inside the Earth, it helps recycle rock to form brand new igneous Rocks

Question 2

What type of rock are fossils found in and explain why

Answer 2

Sedimentary; living organisms on the surface of Earth are buried in sediments that make the rock

Question 3

What is the difference between intrusive and extrusive igneous rock?

Answer 3

Intrusive form inside the Earth (granite), Extrusive form outside the Earth (pumice & obsidian)

Question 4

. The process in which sediments are picked up and moved to another place by ice, water, wind, or gravity.

Answer 4

erosion

Question 5

Part B: Is it a constructive or destructive process?

Answer 5

A constructive process is somthing that builds the world, destructive is when the world lives

Question 6

What is the difference between mechanical (physical) and chemical weathering, and give examples of each

Answer 6

. Mechanical makes rocks smaller without changing the type of rock, chemical changes the rock into a new substance often causing it to become more brittle
Mechanical EX: abrasion, ice & plant wedging, animal burrowing; Chemical EX: oxidation, carbonic acid, hydrolysis, acid rain

Question 7

What weathering process occurs when ice freezes in the cracks of rocks, expands, and breaks the rock onto smaller pieces? Is this an example of mechanical or chemical weathering?

Answer 7

Ice wedging ; mechanical

Question 8

What process can change rocks to a reddish color causing them to become more brittle? Is this physical/mechanical or chemical weathering?

Answer 8

Oxidation ; chemical

Question 9

List the agents of erosion

Answer 9

water, wind, gravity, glaciers

Question 10

What does it mean for soil to be porous

Answer 10

It can hold water because it has more holes

Question 11

What does it mean for soil to be permeable?

Answer 11

Allows more water to pass through the soil

Question 12

Put the soil type on order from the most permeable to the least permeable
Silt, clay, sand

Answer 12

most permeable: sand, silt, clay : Least permeable

Question 13

How does precipitation affect the water table?

Answer 13

Greater the amount of precipitation the more water in the water table

Question 14

What are the 5 factors that affect soil formation, and give a brief description of each

Answer 14

time, Parent rock weathers over time getting smaller to support biota that makes soil
topography, Shape of the land with influence the amount of water 7 sunlight that lead to weather & plant growth
biota, Decomposers (bacteria & mushrooms) speed up the weathering process for soil faster
Parent Material, Materials that is uplifted and weathered to form soil
climate, Soil forms faster in warm moist climate and slower in cold dry climates

Question 15

Define destructive process and give some examples.

Answer 15

Process that destroy the crust of earth; ex. Weathering, subduction

Question 16

Define constructive process and give some examples.

Answer 16

Ex. Deposition, magma cooling, forming taller mountains
