Forces Shaping Earth
| Question | Answer |
|---|---|
| the innermost layer of Earth's interior that is mostly solid iron | inner core |
| lies above the inner core and is made of molten metal | outer core |
| the largest layer of Earth's interior | mantle |
| Earth's outermost layer | crust |
| the rigid upper part of the Earth's mantle and the crust | lithosphere |
| sections of the Earth's crust that move around on the plastic like asthenosphere | plates |
| large fractures in rocks along which movement occurs | faults |
| when one plate sinks underneath another plate | subduction |
| mountains made of huge blocks of rock that are separated from surrounding rock by faults | fault-block mountains |
| mountains formed by the folding of rock layers caused by compressional forces | folded mountains |
| mountains formed when forces inside Earth push up the crust | upwarped mountains |
| mountains that form when layers of lava pile up to form a cone-shape | volcanic mountain |
| the principle that Earth's lithosphere floats on a plasticlike upper part of the mantle called the asthenosphere | isostasy |
