The Rock Cycle
100

A natural, solid mixture of minerals and grains.


A rock


100

A extrusive igneous rock found in the Antrim-Derry Plateau


Basalt


100

What is sediment? 

These small pieces (rocks, plants, animal organisms) that break off of the earth weathering and erosion.

100
Name one example of a metamorphic rock.

quartzite, marble, slate

100

Geologists classify rocks into these 3 major groups.

What are igneous, sedimentary, and metamorphic rocks?

200

The type of rock that forms from magma or lava cooling is called this.

Igneous rock

200

Why are there little to no visible crystals in an extrusive rock?


The lava cooled down quickly on the earth's surface

200

Name two examples of sedimentary rocks.

Sandstone, shale, limestone, conglomerate 

200

What does MORPH mean?

To undergo transformation or change.

200

A rock transforms to sediment by these two processes.

What are weathering and erosion?

300

This type of rock forms from sediments being compacted and cemented together.


Sedimentary

300

Igneous rock that formed from magma and cooled very slowly UNDERNEATH the earth's surface. 

Intrusive

300

What is meant by strata?

Layers

300

How do metamorphic rocks form?

They are sedimentary or igneous rocks that are near magma and get heat from it and pressure from layers above.

300

 I have a sedimentary but then extreme heat and pressure are applied to it. What type of rock will it change into?


A metamorphic rock


400

This type of rock needs heat and pressure to form. 

Metamorphic Rock

400

In what Irish volcanic landform could I find large amounts of granite rock that formed 350 million y/a 

Leinster Batholith

400

Where in Ireland would I find "Old Red Sandstone"

Munster
400

What is meant by contact/thermal metamorphic rock?

It was formed by heat alone

400

I have a metamorphic rock that melts, then cools and crystallizes. What type of rock will it turn into?

Igneous Rock


500

What are the two characteristics geologists use to identify rocks?  


Texture, colour, minerals etc

500

This igneous rock is very light, has holes in it, and can float in water.

Pumice

500

What is Lithification?

Lithification is the process by which loose sediments combine through pressure and cementation to form sedimentary rocks

500

What would have to happen to a metaphoric rock in order for it to change into sedimentary rock?


Weathering and erosion

 

500

I have magma that cools and recrystalises. What rock do I get?

Igneous
