year 8 rocks and the rock cycle revision

Which is the process that breaks up rock on Earth’s surface?

• deposition

• melting

• compaction

• weathering

Geologists have classified rocks into three major groups of rocks which are:

• inorganic, organic and chemical rocks

• igneous, sedimentary and metamorphic rocks

• metamorphic, chemical and non chemical rocks

• sedimentary, inorganic and igneous rocks

Any rock that forms from another rock as a result of changes in heat or pressure (or both) is a:

• chemical rock

• igneous rock

• sedimentary rock

• metamorphic rock

What kind of igneous rock usually contains large crystals?

• clastic

• extrusive

• organic

• intrusive

A rock that forms from many small fragments of other rocks is a(n)

• igneous rock

• metamorphic rock

• sedimentary rock

• extrusive rock

The process by which metamorphic rock changes to igneous rock begins with

• melting

• erosion

• deposition

• crystallization

A naturally occurring solid that can form by inorganic processes and that has a crystal structure and a definite chemical composition.

• It´s a rock

• It´s a crystal

• It´s a mineral

• It´s a substance

To be classified as a mineral, a substance must satisfy this

requirement

• have a definite chemical composition

• naturally occurring

• be a solid

• all the above

The streak of a mineral is the

• color of the rock

• when it carved a line in a surface

• is the color of it´s powder

• is its hardness

Limestone is an example of...

• Sedimentary

• Igneous

• Metamorphic
