It is called the geothermal gradient, which means that the closer to the mantel or core (underground) you go, the hotter it gets.
below the surface of the earth, as we move deeper towards the core (HEAT's CAUSE) the temperature rises. this rise of temperature with depth is referred to as the geothermal gradient. in most parts of the world that are away from the plate boundaries, with every km depth an increase of 22 degrees Celsius in temperature is observed. Different areas show different geothermal gradients. in many parts of the world its as high as 30 degrees Celsius per Km and in some its as low as 15 degrees Celsius per Km.
30 degrees Celsius for each kilometer of depth near Earth's surface
increase
A gradient is another way of describing rate of change. In this case it's temperature per unit distance.A very simplified estimate of the geothermal gradient of the earth could therefore be made based on the difference in temperature at the earth's core and surface divided by the radius of the earth.Temperature at Earth's core = 7300 KTemperature at surface = 283 KChange in temperature from surface to centre of core = 7300 - 273 = 7027 KRadius of Earth = 6,378.1 km.7027 / 6378.1 = 1.1 K/kmIn other words using this very very simplified estimate the temperature increases by 1.1 K for every 1000m further you travel into the ground.NB: The actual geothermal gradient will vary with depth and will be significantly more complex then that quoted here!
gradient
This is called the "geothermal gradient".

Temperature and pressure increase with increased depth into the Earth.
Geothermal gradient is the rate of increasing temperature with respect to an increasing depth in the Earth's interior. It is approximately 25 degrees Celsius per kilometer of depth.
It is called the geothermal gradient, which means that the closer to the mantel or core (underground) you go, the hotter it gets.
True. Temperature and pressure both increase with increasing depth within the Earth.
Both temperature and pressure increase with depth.
Both temperature and pressure increase as depth increases.
Geothermal gradient is the increase of temperature in relation to the increasing depth in the Earth's interior. The Earth's internal heat source comes from the joined forces of residual heat from planetary accretion and heat produced through radioactive decay. It may also come from other sources.
