I will tell you some really good facts about volcanoes and earthquakes.

HOW PEOPLE MEASURE EARTHQUAKES:

. They use a thing called a ricter scale and a mercalli scale

HOW TO STAY SAFE DURING AN EARTHQUAKE:

1. Get down on the floor

2. Cover you head and neck with your arms

3. If possible, get under a strong piece of furniture

4. Try to hold on and wait for the shaking to stop

LAYERS OF THE EARTH:

on the first layer there is the crust which is round 1000-2000km thick. Under that is the mantle, it is round 3000 degrees. Under that layer is the outer core, it is round 4000 degrees. And in the centre of the earth, there is the inner core, it is round 5000 degrees.

HOW A VOLCANO IS FORMED:

When a volcano erupts, lava comes out. After a while, the lava will dry on top of the Volcano, which will cause the volcano to be larger.

HOW A VOLCANO ERUPTS:

Pressure in the earth causes magma go up,  the magma goes through a magma chamber To get to the main vent. Some magma might break through the volcano and comes out on the side.
