​ Unit 3 Review

TEKS 6.5B, 6.10A, 6.10B​

​6.10A build a model to illustrate the compositional and mechanical layers of Earth, including the inner core, outer core, mantle, crust, asthenosphere, and lithosphere

​

Multiple Choice

Compositional layers from INSIDE to OUTSIDE

• crust, mantle, outer core, inner core

• inner core, outer core, mantle, crust

• outer core, inner core, crust, mantle

• mantle, crust, inner core, outer core

Multiple Choice

Mechanical layers from OUTSIDE to INSIDE

• Lithosphere, Asthenosphere, Mesosphere, Outer Core, Inner Core

• Inner Core, Outer Core, Mesosphere, Asthenosphere, Lithosphere

• Asthenosphere, Lithosphere, Mesosphere, Inner Core, Outer Core

• Lithosphere, Mesosphere, Asthenosphere, Outer Core, Inner Core

Multiple Choice

Because of the amount of pressure on it, the inner core is...

• liquid

• solid

• plasma

• gas

Multiple Choice

What is the other layer that is also solid?

• asthenosphere

• lithosphere

• mesosphere

Multiple Choice

Which layer is the hottest layer, made of iron and nickel?

• lithosphere

• asthenosphere

• mantle

• core

​6.10(B) classify rocks as metamorphic, igneous, or sedimentary by the processes of their formation

​Igneous rocks are formed at the base of volcanoes. They can appear glassy OR very grainy.

​1. Melt

2. Cool

3. Harden​

​Metamorphic rocks are rocks that have been changed by heat and pressure. They started out as igneous, sedimentary, or other metamorphic rocks.

​Sedimentary rocks are formed in layers. The layers compact and cement to form rocks.

Multiple Choice

How are sedimentary rocks made?

• at the base of a volcano

• they are changed by heat and pressure

• materials are pressed together

• earthquakes cause small pieces to fall

Multiple Choice

What do igneous and sedimentary rocks have in common?

• they are both striped

• they are both formed from cooled lava

• they can both be turned into a metamorphic rock

• theya re both made in layers

Multiple Choice

What type of rock contains fossils?

• Igneous

• Metamorphic

• Sedimentary

• Extrusive igneous rock

​6.5(B) recognize that a limited number of the many known elements comprise the largest portion of solid Earth, living matter, oceans, and the atmosphere

​H20

​Silicon and Oxygen

Multiple Choice

65% of living matter is made of which element?

• Oxygen

• Nitrogen

• Carbon

• Silicon

Multiple Choice

The oceans and other bodies of water (The Hydrosphere) primarily are composed of which elements?

• Hydrogen and Oxygen

• Oxygen and Sodium

• Sodium and SIlicon

• Oxygen and Silicon

Multiple Choice

What two main elements are in Earth's crust?

• Nitrogen and Silicon

• Oxygen and Silicon

• Oxygen and Nitrogen
