Chapter 3 - Rocks Test Wednesday

Which of following is not one of the three classes of rocks? Igneous Metamorphic Magma

What two processes change rock into sediments? Cooling & Hardening Heat & Pressure Weathering & Erosion

What two things can change sedimentary and igneous rocks into metamorphic rocks? Cooling & Hardening Heat & Pressure Weathering & Erosion

What is the only kind of rock that can form directly from magma? Igneous Metamorphic Sedimentary

All rocks are made up of Lava Sediments Magma Minerals

The grouping of things that are alike is the science of Petrology Classification Geology Biology

Rocks formed when melted minerals cool and harden are classified as Molten rocks Sedimentary rocks Igneous Rocks Lava Rocks

Magma that reaches Earth’s surface is called Lava Molten Igneous Conglomerate

Molten rock is made up of Melted minerals Lava Obsidian Iron and Nickel

The mineral crystals of a rock formed from magma usually are Small Large Fine Cubic

Rocks formed from the remains of living things are classified as Metamorphic Igneous Sedimentary Lava

Limestone and halite are examples of Clastics Nonclastics Foliated Nonfoliated

A rock formed when another rock is changed by heat and pressure is classified as Metamorphic Igneous Sediment Clastic

The series of natural processes by which rocks are slowly changed from one type to another is Sedimentation The Rock Cycle Classification Petrology

A metamorphic rock that has mineral crystals arranged in bands is Unfoliated Foliated Clastic Nonclastic

The texture of an igneous rock that does NOT have mineral crystals is Fine Clastic Glassy Foliated

Quartzite is formed from Halite Sandstone Shale Pyrite

Coal is a sedimentary rock formed from Lava Plants Chemicals Magma

Two minerals commonly found in igneous rocks are mica and Halite Feldspar Pyrite Silver
