Rock Cycle, Earth Layers & Plate Tectonics

The outermost solid layer of the Earth is called the

• mantle
• outer core
• inner core
• crust

The layer that lies beneath the mantle and surrounds the inner core. 

• mantle
• outer core
• inner core
• crust

Is a layer of week of soft mantle that is made of rock that flows slowly.  Tectonic plates move on top of this layer. 

• Inner Core
• Asthensophere
• Lithosphere
• Outer Core

This is the outermost, rigid layer of the Earth, made up of two parts, is divided into pieces call tectonic plates.

• Inner Core
• Asthensophere
• Lithosphere
• Outer Core

A dense ball of solid iron and nickel.

• crust
• inner core
• mantle 
• outer core

Is the outer core a liquid or solid?

• liquid
• solid

Which type of rock forms from extreme heat and pressure?

• Igneous
• Sedimentary
• Organic
• Metamorphic

A metamorphic rock changes into an igneous rock by what two processes?

• Melting and cooling
• Extreme heat and pressure
• Compaction and cementation
• Weathering and erosion

Wind, water, and ice breaking down rock is called

• Erosion
• Deposition
• Compaction
• Weathering

What is the MAIN way rocks are classified?
