Types of Rocks Test Mr. Barr
2
1 When sediments are compacted and cemented together, this type of rock is formed. Sediments Sedimentary Metamorphic Igneous Magma
3
2 A rock exposed to high heat and pressure can change form and turn into this type of rock. Sediments Sedimentary Metamorphic Igneous Magma
4
3 Any rock can be mechanically or chemically broken down into pieces called _________________. Sediments Sedimentary Rock Metamorphic Rock Igneous Rock Magma
5
4 When magma cools and crystallizes this type of rock forms. Sediments
Sedimentary Metamorphic Igneous Magma
6
5 When the melting point of the minerals in a rock are reached ______________ will form. Sediments Sedimentary Rock Metamorphic Rock Igneous Rock Magma
7
6 A rock formed from cemented pieces of preexisting rock is called a(n) ______________ sedimentary rock. Clastic Chemical Biologic Organic Intrusive
8
7 Magma that cools in the ground will form a(n) _________________ igneous rock. Foliated Non-foliated Intrusive Extrusive Chemical
9
8 When rock is exposed to great pressure the minerals can separate into bands or layers to create a(n) _________________ metamorphic rock. Foliated Non-foliated Intrusive Extrusive Chemical
10
9 Some rocks form from the minerals in water precipitating (coming together). This type of rock is called a(n) ________________ sedimentary rock. Clastic Chemical Biologic Organic Intrusive
11
10 When lava cools at the surface of a volcano or at a mid-ocean ridge, a(n) _________________ igneous rock will form. Foliated Non-foliated Intrusive Extrusive Chemical
12
11 When a rock forms from the remains of living organisms it is called an organic or _______________ sedimentary rock. Clastic Chemical Biologic Foliated Intrusive
13
