THE LAYERS OF THE EARTH by Mind Map: THE LAYERS OF THE EARTH

1. GEOSPHERE: is made up of three layers

1.1. CRUST

1.1.1. is the Earth outer layer.

1.1.2. it is made up of solid materials.

1.2. MANTLE

1.2.1. is the Earth middle layer.

1.2.2. it is extremely hot.

1.2.3. in some parts there is stigma (red-hot liquid rock)

1.3. CORE

1.3.1. is the Earth inner layer.

1.3.2. it is also extremely hot.

1.3.3. it is divided into:

1.3.3.1. the liquid outer core.

1.3.3.2. the solid inner core.

2. HYDROSPHERE: all water on Earth makes up the hydrosphere.

2.1. WATER: is usually a liquid, but it can also be a solid or a gas.

2.1.1. Water in liquid forms covers most of the Earth´s surface. It is founds in oceans, seas, rivers and lakes.

2.1.2. Water in solid forms (snow and ice) is found in the polar regions. It ia also found on mountains. Water vapour . a gas, is found in the atmosphere.

3. ATMOSPHERE: is the air which surrounds the Earth.

3.1. TROPOSPHERE

3.1.1. is the lowest layer.

3.1.2. most gases are in this layer.

3.1.3. plants and animals live in the troposphere.

3.2. STRATOSPHERE

3.2.1. is the next layer.

3.2.2. there is a thin layer of ozone in the upper stratosphere. This is called ozone layer.

3.2.3. as wel travel higher, the gases become less dense.

3.2.4. in outer space there is no atmosphere.
