One rock is formed from rapidly cooling and is smooth and glassy.
This rock is formed from slow-cooling magma and large crystals can be seen. Name the rock property that allows you to identify it.
What is texture?
100
To group items based on their similarities.
What is classification?
100
The Natural process by which atmospheric and environmental agents, such as wind, rain and temperature changes, breakdown rocks.
What is Weathering?
100
A loose mixture of rock fragments, organic material, water and air that can support the growth of vegetation (plants).
What is soil?
200
Formation of molten rock aka magma solidifies.
What is Igneous Rock
200
Minerals break apart in chunks and random size pieces.
What is Fracture?
200
Solid, geometric forms of minerals produced by a repeating pattern.
What are crystals?
200
The process by which wind, water, ice or gravity transports soil and sediment from one location to another.
What is Erosion?
200
Dark, organic matter formed in soil from the decayed remains of plants and animals.
What is humus?
300
Gooey hot mess deep inside.
What is magma
300
I say Cemented and Compacted.........you say
What is Sedimentary Rock.
300
This is the softest mineral (like a pillow) and this is the hardest mineral (like steel)
What is Talc and Diamond?
300
A series of processes in which rock changes from one type to another. Ex: Igneous rocks can become metamorphic and sedimentary rocks.
What is the Rock Cycle?
300
These are the factors that affect soil formation. Name 3.
What is geological, biological, chronological, topographic, climate?
400
Igneous Rock melts and turns into this.
What is magma?
400
After millions of years you might find what looks like a fish inside of these rocks.
What is Sedimentary Rocks
400
Let's make a chart chart showing how hard minerals are.
What is Moh's Hardness Scale?
400
The act of crushing or increasing the density of a material. (Smash, smoosh, squash, squeeze)
What is compacted?
400
Clay, sand, and humus
What is a good combination for growing plants?
500
Let's add heat and pressure to Igneous Rock and see what rock it turns into.
What is Metamorphic Rock?
500
The stage between Igneous Rocks and Sedimentary Rocks weather and erode forming.
What is Sediment?
500
Minerals can be identified using hardness, streak, and cleavage.
What are the different recognizable properties of Minerals?
500
The process in which the material is laid down or dropped.
What is deposition?
500
This property of soil helps you tell how fertile it is.
