What happens to temperature and pressure as the depth within the Earth increases?

Diffusion is the movement of particles from a high to low particle concentration, while osmosis is the movement of water from a high to a low water concentration.

Temperature and pressure progressively increase with increased proximity to Earth's core. Recent studies indicate the core's temperature may be close to 11,000 degrees Fahrenheit; that's nearly 2,000 degrees warmer than previously thought and hotter than the surface of the Sun, according to a 2013 Forbes article.
