Term
Difference between a rock and a mineral.
4.1 |
|
Definition
minerals are made up of elements or compounds while rocks are made up of groups of minerals, or other rocks |
|
|
Term
Describe the rock cycle and the changes that a rock may undergo.
4.1 |
|
Definition
first can undergo chemical or mechanical weathering, then can break apart, and erosion.Older sediment is buried and compacted by new layers. It can also be buried and heated and become metamorphic rock. |

mixture of minerals, mineraloids, glass or organic matter |

|
|
Term
|
Definition
A rock formed by the cooling of molten material from a volcano or from deep inside Earth. |
|
|
Term
|
Definition
Molten rock from a volcano flowing onto Earths surface. |
|
|
Term
|
Definition
Igneous rocks formed when magma cools below Earth's surface; generally have large mineral grains. |
|
|
Term
|
Definition
Igneous rocks that form when magma extrudes [forces] onto Earth's surface and cools as lava; have a fine-grained texture. |
|
|
Term
|
Definition
Light-colored igneous rocks formed from a magma rich in silicon and oxygen. |
|
|
Term
|
Definition
Dark-colored, dense igneous rocks that form from magma rich in iron and magnesium. |
|
|
Term
Magma and lava are the materials that cool to form igneous rocks.
4.2 |
|
Definition
|
|
Term
contrast the making of intrusive and extrusive rocks.
4.2 |
|
Definition
Intrusive rocks form below Earths surface. Extrusive rocks form on Earths surface. |
|
|
Term
contrast granitic and basaltic igneous rocks.
4.2 |
|
Definition
Basaltic rocks are dense, heavy, dark-colored rocks that form from basaltic magma(which is rich in iron and magnesium). Granitic rocks are light-colored rocks of a lower density than basaltic rocks. (Granitic magma is thick and stiff and contains a lot of silicon and oxygen.) |
