Name 3 characteristics of inner and outer planets.
Inner: rocky, less moons and rings, shorter orbit around sun.
Outer: gas, larger, more moons and rings longer orbit around sun
What are variables called that you measure and how can you organize them?
Dependent Variable-graphs, charts, diagrams
What is the definition of weathering, erosion, and deposition?
Weathering-breaking down of rocks
Erosion-moving rocks and sediment to a new location
Deposition-rocks and sediments piled up
How are Sedimentary, Metamorphic and Igneous rocks formed?
Sedimentary-small pieces of rock, dead plants and animals cemented together.
Metamorphic-Heat and pressure deep in the Earth
Igneous-magma under ground shooting out of volcanos and lava cooling.
What is the difference between a rock and a mineral?
Rocks are made of minerals but minerals are not made of rocks. A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties.

Erosion-Moving water: rivers, oceans, rain, wind glaciers landslides
Weathering: Root wedging, water, wind, ice wedging temperature changes
