Earth's Materials and Tectonic Plates

  Which of the following models would best represent the inner and outer core of Earth, based on the physical characteristics of each layer?

• A metal ball bearing (solid) suspended in oil (liquid)
• Gelatin (red semi-solid) on top of a cracker (brittle solid)
• A ball of clay (solid) filled with water (liquid)
• Rubber ball (flexible solid) painted red (thin solid covering)

The lithosphere consists of the –

• upper mantle and the crust.
• lower mantle and the outer core.
• inner and outer core.
• crust and the entire mantle.

The layer of Earth that is found directly below the lithosphere is called the -

• crust
• asthenosphere
• inner core
• outer core

Which of Earth’s layers has the lowest density?

• crust
• inner core
• mantle
• outer core

According to scientific data, which layer of Earth is the thickest?

• crust
• inner core
• mantle
• outer core

Oceans, and other bodies of water, are found on which layer of Earth?

• outer core
• mantle
• inner core
• crust

Which layer of Earth is broken up into giant moving plates?

• asthenosphere
• lithosphere
• inner core
• outer core

The mantle does not behave the same throughout. In places where the mantle flows like a liquid, it does so because it -

• is being moved by plates.
• is under more pressure.
• has melted completely.
• has existed for longer.

• Location A
• Location B
• Location C
• Location D

Which layer of Earth is the thinnest?

• crust
• mantle
• outer core
  outer core
• inner core
  inner core
