What happen to temperature & pressure 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

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