Rocks

Question 1

Weathering

Answer 1

The breaking down of Earth’s materials by natural processes (water, wind, ice, chemicals, etc.) into smaller pieces or sediments

Question 2

Erosion

Answer 2

Weathered rock and soil particles are moved from place to place by water, wind, or ice

Question 3

Deposition

Answer 3

Weathered sediments are laid down in a new location helping create new landforms or rocks

Question 4

Melting

Answer 4

Caused by heat and pressure around the rock to form magma

Question 5

Solidification

Answer 5

Magma or lava cools and hardens

Question 6

Re-crystallization

Answer 6

Through heat and pressure, the rock’s atoms and crystals are rearranged

Question 7

Igneous Rock

Answer 7

Formed from the cooling and solidification of magma or lava

Question 8

Extrusive Igneous Rock

Answer 8

Formed above ground from lava cooling and hardening

Question 9

Intrusive Igneous Rock

Answer 9

Formed below ground from magma cooling and hardening

Question 10

Sedimentary Rock

Answer 10

Formed from sediments (rock fragments, mineral grains, animal or plant remains) that are pressed or cemented together

Question 11

Law of Superposition

Answer 11

States that layers and fossils on top are younger than lower layers

Question 12

Metamorphic Rock

Answer 12

Rock changes due to intense heat and high pressure then recrystallizes
