Structure of the Earth

What are the three main layers of the Earth?

• Mantle, Crust, Inner Core

• Lithosphere, Asthenosphere, Mesosphere

• Crust, Mantle, Core

• Magma, Crust, Core

Which layer of the Earth is the thinnest?

• Mantle

• Outer core

• Crust

• Inner core

What is the Earth's crust made of?

• Crystallized water

• Liquid metal

• Frozen lava

• Solid rocks

What are tectonic plates and how do they move?

• Tectonic plates are underground tunnels that transport magma and move due to volcanic eruptions.

• Tectonic plates are giant mirrors that reflect sunlight and move due to solar radiation.

• Tectonic plates are small rocks that float on water and move due to wind currents.

• Tectonic plates are large slabs of rock that make up the Earth's lithosphere. They move due to the heat generated from the Earth's core, causing convection currents in the semi-fluid asthenosphere below the plates. This movement results in the plates either colliding, moving apart, or sliding past each other.

What happens when tectonic plates collide?

• Formation of mountains, earthquakes, or subduction zones

• Formation of deserts, volcanic eruptions, or ocean currents

How are volcanoes formed?

• Volcanoes are created by underground nuclear explosions.

• Magma from the Earth's upper mantle erupts through the Earth's crust, forming a volcano.

• Volcanoes are formed by meteorite impacts on the Earth's surface.

• Volcanoes are a result of excessive rainfall in a region.

What is the Ring of Fire?

• The Ring of Fire is a jewelry store chain

• The Ring of Fire is a region around the Pacific Ocean known for its seismic and volcanic activity.

• The Ring of Fire is a popular dance move

• The Ring of Fire is a type of dessert

What are some safety measures to take in case of a volcanic eruption?

• Stay near the lava flow

• Stay indoors, wear a mask, follow evacuation orders, avoid low-lying areas

• Ignore evacuation orders

• Run towards the volcano
