What happen to temperature & pressure as you go deeper into the earth

The temperature and pressure increases as you go deeper into the earth.

Both temperature and pressure increase as you get closer to the Earth's centre.

Explanation:

The pressure increases as you go deeper because there is always more weight from above.

The pressure goes from 1 atm at the surface to 3.5 * 10⁶ atm in the core.

The core is hot because of

residual heat from when the Earth was formed the energy released by decay of radioactive elements.

Here's a table of approximate temperatures in the various layers.

Layer T/°C

Crust 300

Upper mantle 1300

Lower mantle 3300

Outer core 4500

Inner core 6000
