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

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.

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.
