The Earth

1.What´s inside the earth?

There are mani layers. The crust, mantle & core.

1.1.The lithosphere:

The lithosphere is a outermost shell of a rocky planet , tehe Earth

2.Tectonic plates:

2.1.What´s a tectonic plate?

Plate tectonics describes the large scale motions of Earth's lithosphere. They are pieces of the Earth's crust and uppermost mantle, together referred to as the lithosphere. Tectonic plates are a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere.

2.2. Major tectonic plates of the world: The major tectonic plates are between the oceanic Nazca Plate and the continental South American Plate more or less and they move around the Mid-Atlantic Ridge.Where plates diverge, hot, molten rock rises and cools adding new material to the edges of the oceanic plates.

3.Continets:

3.1 Continental drift:

Continental drift is the movement of the Earth's continents relative to each other.The first contineltal drift was in 1596 by Abraham Orteliu.Today the scientist whith satellites and lassers can show how much continents are still drifting this year.For example that Africa and South America are drifting apart at the rate at 3.5 centimeters at the year.

4.Plate movement:

4.1.Earthquake:

An earthquake is the result of a sudden release of energy in the Earth's crust that creates seismic waves.

The earthquakes can cause big disasters!

4.2.Volcanoes:

A volcano is an opening, or rupture, in a planet's surface or crust, which allows hot, molten rock, ash, and gases to escape from below the surface.
