Rocks (Fill in the blanks)
Rocks are ________ occurring solid mixtures of Earth material created through geological processes.
Naturally
These are non-living substances with 5 properties found on Earth's surface and deep inside the crust.
Minerals
These rocks form when hot, molten rock (lava or magma) cools and solidifies.
Igneous
I am the way an object emits light from the electromagnetic spectrum. What am I?
Color
Minerals cannot be identified using various tests such as hardness, color, luster, streak and breakage.
False. They can be identified using those tests.
_______ rocks form below Earth's surface and have rougher textures.
Intrusive
There are this number of different minerals on Earth and we use them in our everyday lives.
Thousands
These are rocks that have formed form sediments from pre-existing rocks or pieces of once living organisms.
Sedimentary
I am the metallic or non metallic reflection of light off a mineral's surface. What am I?
Luster
Latin word for fire is lava.
False.
Igneous is the Latin word for fire

Economic gain
These rocks form deep below Earth's surface and are subjected to high heat and intense high pressure.
Metamorphic rocks
I measure whether a mineral will scratch or be scratched. What am I?
Hardness
Extrusive igneous rocks form below Earth's surface and have rougher textures.
False.
Extrusive rocks form on top of Earth's surface and have smoother textures.
Rocks are made mostly of __________ and are identified primarily by the minerals they contain and their ________.
Minerals , texture.
Fill in the blank
Minerals make up all of earth's _______, ________, and ________ and can be found everywhere.
Rocks, sands and soils
These rocks form the multiple geological processes called erosion, weathering, deposition, compaction and cementation.
Sedimentary rocks
I am the way a mineral splits off itself. Either cleavage or fracture. What am I?
Breakage
Rocks are an important part of our society and help us both directly and indirectly.
True
Rock texture refers to the physical appearance and feel of a rock determined by the ________, ________, ________ and ______ ___ ____ ___________.
Size, shape, arrangement and distribution of its minerals.
The 5 properties a mineral must possess in order to be classified as a mineral.
Naturally occurring
Inorganic
Solid
Crystal Structure
Chemical composition
These rocks are divided into two groups (intrusive and extrusive) depending on where the molten rock formed.
Igneous rocks
I am the color of a mineral's powder when it is scratched against a plate. What am I?
Streak
Rocks form the Earth's inner layer and a re classified based on how they formed, what they're made of and their texture.
False
Rocks form the Earth's outer layer and a re classified based on how they formed, what they're made of and their texture.
