Geologists classify rocks into 3 major groups

What is igneous, sedimentary, and metamorphic

100

Minerals that precipitate from evaporation are called

mineral deposits

100

Changes in enormous quantities of rock over a wide area caused by extreme pressure from overlying rock or from compression caused by geologic processes

Regional metamorphism

100

This is how metamorphic rocks are created.

What is extreme heat and pressure

100

Magma cools and crystallizes in the cycle forming _______ rock

What is intrusive igneous rock

100

This common rock-forming minerals that form tetrahedrons which can form rocks like feldspar and quartz.

 

 Silicates

 

100

This is the reason new minerals form in a metamorphic process

The need for stability

200

The type of rock that forms from magma or lava cooling

What is igneous rock

200

This type of rock is formed from lava ON the earth's surface.

What is extrusive igneous rock

200

These are the building blocks of rocks


Minerals

200

These types of rocks can become metamorphic rocks

What is igneous, sedimentary and other metamorphic rocks

200

Igneous rock transforms to sediment by processes called ___________ & ____________

What is weathering and erosion

200

Rocks with different textures but that are made of the same minerals have this


What is different names? 

 

200

This is the driving energy source behind the formation of igneous and metamophic rocks

Earth's interior

300

This is the term for a solid that has been released from a solution of evaporating water or liquid

Precipitate

300

  An extrusive rock with dark color, fine grains and low silica


  What is basalt.  

300

The type of rock are fossils most likely to be discovered in

Sedimentary rock

300

The formation of these rocks is driven largely by the Sun.

Sedimentary rocks

300

The process where layers of sediment become pressed together over time

What is compaction

300

Flat layers that form in rocks as rocks are squeezed by pressure

foliation


300

Rocks are generally identified by this means.


Texture and the mineral they contain

400

What should be replacing the question mark?

 

What is deposition or sedimentation?

400

This type of felsic igneous rock is black with a glassy texture.

What is obsidian

400

Formed by the accumulation of dead plant matter or animal remains being cemented together. 


What is Coal

400

The texture of a metamorphic rock arranged in parallel layers (bands) is called

What is foliated

400

Changes in a rock that is in contact with magma due to the magma's extreme heat


Contact Metamorphism

400

If rocks cool slowly describe the size of the crystal it will produce

What is large?

400

Describe sediment?

What is pieces of rock, sand and dirt? 

 

500

Igneous rock cools very quickly.When it forms the appearance could be described as _________.

What is smooth or shiny or no visible crystals (glassy or vitreous)

500

This extrusive igneous rock can float in water, and some people use it to clean their feet. It has many air bubbles. 

What is pumice

500

The three groups of rocks are classified by this means

how they were formed

500

Two igneous rocks may be made from the same minerals but have different names due to this.

They may have different textures

500

The processes by which sediments become sedimentary rocks - three words

Deposition, compaction or cementation

500

If granite undergoes high heat and pressure within the Earth, what type of rock will be formed.

Gneiss (a metamorphic rock)

500

What conditions are required for an organism to be fossilized?

(1) Organisms must contain hard parts such as bones, teeth, cartilage, or shells. (2) The organic material must be buried quickly in an oxygen-free environment protected from scavengers.
