2
|
A type of metamorphic rock formed when limestone is pushed down into the earth and subjected to intense heat and pressure for a long period of time.
|
4
|
Imprints of leaves, shells, insects, or other items left in rock.
|
7
|
Hot, molten rock found deep inside the earth.
|
9
|
One of the three main rock types, formed deep within the earth, where rock material changes after being subjected to intense heat and pressure (squeezing).
|
10
|
The recurring series of events that rocks undergo, over time, that transforms them from one type to another.
|
11
|
The process by which rocks are worn down by wind and water, creating sediment.
|
12
|
A type of sedimentary rock made up of stones/particles pressed together by waves/water. Conglomerate is often found in large expanses or beds.
|
13
|
A process that turns sediment into sedimentary rock. Sediment accumulates and weight presses the sediment particles together, compacting them.
|
17
|
One of the three main rock types, formed from sediment particles. Gradually, the sediment accumulates in layers and over a long period of time hardens into rock.
|
18
|
A type of sedimentary rock often found near oceans and composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3).
|
|
|
|
|
1
|
Loose particles of minerals, rocks, shells, pebbles etc
|
3
|
The process by which soil, sediment, and small pieces of rock are carried away from their original locations and transferred elsewhere by the actions of wind, water, ice, or living organisms.
|
5
|
A type of extrusive igneous rock, created from lava that cools so quickly that no crystals can form on its surface. It can be found near volcanic lava flows.
|
6
|
One of the three main rock types, formed from the cooling and hardening of magma.
|
8
|
An opening in the earth's surface that allows hot magma, ash, and gases to escape from deep below the surface.
|
9
|
From the Greek 'to transform,' metamorphosis is the change that occurs when rocks under the earth's surface are subjected to intense heat and pressure, turning them into metamorphic rocks.
|
14
|
The process that hardens magma and turns it into igneous rock. The cooling of magma can occur either underneath or on the earth's surface.
|
15
|
A type of metamorphic rock that usually has ribbon like layers.
|
16
|
A type of igneous rock and the most common rock type in the earth's crust and makes up most of the ocean floor.
|
19
|
The process that turns any rock into magma. Melting a rock requires extremely high temperatures, which only occur far beneath the earth's surface.
