Rocks
A category of rock formed in layers of sand, soil,clay, gravel and other sediment that is built up in one location overtime.
What is sedimentary rock?
A kind of weathering that occurs when rocks are broken down by physical force without any change in their chemical structure.
Mechanical weathering.
Define erosion.
What is The transport of sediment by wind, water or gravity.
True or False: Salt is a mineral
True!
A category of rock formed when hot liquid rock (lava or magma) cools into a solid. What type of rock is this?
What is igneous rock ?
A kind of weathering that occurs when chemical reactions change the composition of rocks, rearranging the atoms or molecules into new substances with different properties. What type of weathering is this?
A kind of weathering that occurs when chemical reactions change the composition of rocks, rearranging the atoms or molecules into new substances with different properties.
What is a system?
What is A set of connected, interacting parts that form a more complex whole ?
define mineral.
What is A naturally occurring, inorganic solid with a crystal structure ?
A category of rock formed in chemical reactions where one type of rock is changed by pressure or heat into a new type of rock with different properties. What type of rock is this?
What is metamorphic rock ?
A type of mechanical weathering that occurs when rocks and sediments grind against each other.
What is abrasion ?
The breakdown of rock into smaller pieces from exposure to wind, water,changes in temperature, and/or biological forces; there are two kinds; mechanical and chemical, what is this the definition of?
Weathering
How diamonds are formed?
Define a rock.
Mixed mineral matter that makes up the surface of the earth and other terrestrial objects.
A plant grows and its roots push into a rock’s cracks, slowly breaking the rock apart. Is this mechanical or chemical weathering?
Mechanical
Drifting slabs of solid rock called plates, that make up the earth's surface.
What are tectonic plates?
What is the hardest mineral? (we learned this in the science lab)
What is a diamond?
What are the phases of the rock cycle?
Weathering & Erosion , Deposition , Heat & Pressure , Melting and Cooling & Crystallization
Water mixes with minerals in rocks and causes them to change over time. Is this mechanical or chemical weathering?
Chemical
What is the rock cycle?
The process that form, break down, and reform rock from one category to another.
Properties scientist use to identify minerals, give at least 3
luster, hardness, conductivity, color, transparency, streak
