Earth’s Systems & Resources

,Earth’s Structure

Quick facts about earth

- It was formed around 4.6 billion years ago
- It is the third planet away from the sun in the solar system
- It is the only planet known to support life

Earth can be divided into three sections:

- the biosphere: includes all forms of life (plants and animals)both on land and in the sea.
- the hydrosphere: includes all forms of water (freshwater, saltwater, snow, and ice)
- the internal structure: divided into the crust, mantle, and core

,Layers of the Earth

The lithosphere is the
solid, outer part of
Earth. Earth consists of
three main layers: (1)
the core, or the inner
layer; (2) the mantle, in
the middle; and (3) the
crust, which includes the
continents and the
ocean floor.

, Core

The core is composed mostly of iron and is so hot that the outer core is
molten.

The inner core is under such extreme pressure that it remains solid
