Describe how the solar system formed in four steps.

1. Solar nebula formed (cloud of gas, ice, and dust) 2. Gravity flattened nebula out into a disk shape. 3. Disk started spinning. Gravity pulled densest materials went to center forming our Sun 4. Gravity pulled leftover materials together and formed our planets.

Describe the inner core & outer core. How are they different?

-Outer Core: Liquid. made out of iron & nickel.

-Inner core: Solid. made out of solid iron crystals.

500
What is elevation?
term used to describe height above sea level.
500
Define landform.
Topographic features formed by processes that shape the earth.

Describe each layer of the earth. (4)

CRUST- thinnest layer. rocks made out of oxygen and silicon. two types are oceanic and continental. MANTLE- thickest layer. rocks contain iron and magnesium. asthenosphere- plastic layer. lithosphere- uppermost mantle and crust. OUTER CORE- liquid. made of iron and nickel.Second densest layer. INNER CORE- solid. made of solid iron crystals. spins faster than rest of earth.
