Rocks

Minerals form the building blocks of rocks. These rocks can be (multiple answers possible)

• igneous

• metamorphic

• sedimentary

• conclavic

The highlighted rocks have large crystal structures

• True
• False

The rocks that can be considered vesicular are

• obsidian

• pumice

• granite

• pegmatite

When igneous rocks cool quickly they are said to be

• extrusive

• intrusive

• malformed

• intrinsic

Gabbro could be described as

• extrusive with coarse crystal structure

• non-vesicular with fine texture

• non-vesicular with coarse texture

• glassy texture and intrusive

It would be true to say

• as the cooling time increases the crystal size increases

• large crystals can only occur if things cool quickly

• there is an inverse relationship between crystal size and time

• the longer the cooling time the smaller and finer the crystal size

Match the following.

• due to heat and pressure

• Sedimentary Rocks

• formed directly from molten magma

• Metamorphic Rocks

• rock sediments cemented or compacted

• Igneous Rocks

Match the following

• Compaction

• 
• Cementation

• 
• Weathering and Erosion

• 
• sediments

•
