What layer of the earth is made of soild iron and nickel?

• innner core
• mantle
• crust
• outer core

The correct order of the Earth's layers starting from the OUTSIDE going IN is

• crust, inner core, mantle, outer core

• mantle, outer core, inner core, crust

• crust, mantle, outer core, inner core

• inner core, outer core, mantle, 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

The process by which metamorphic rocks are formed...

• heat and pressure
• erosion and deposition
• melting and cooling

The process by which igneous rocks are formed...

• heat and pressure
• melting and cooling
• weathering and erosion

Rock that forms when sediment from older rocks get pressed and cemented together.

• Sedimentary Rock
• Metamorphic Rock
• Igneous Rock

What type of boundary is formed when plates separate?

• convergent
• horizontal
• divergent
• transform

What type of boundary is formed when plates collide?

• convergent
• horizontal
• divergent
• transform

What is the approximate age of Earth?

• 4.6 billion years

• 4.6 million years

• 46,000 years
