WebBetween 85 and 90 percent of Earth’s iron is concentrated in the core. The increasing pressure with depth causes phase changes in crustal rocks at depths between 5 and 50 km (3 and 30 miles), which marks the top of the upper mantle, as mentioned above. This transition area is called the Mohorovic̆ić discontinuity, or Moho. WebApr 8, 2024 · These are the upper mantle, which reaches a depth of 410 km from the surface, the transition zone which reaches a depth of 410 km, the lower mantle, which reaches a depth of 2,891 km, and the core-mantle boundary which has a variable thickness (200 km or 120 mi on average). There are two major zones in the upper mantle.

Grades 9 - 12+ article Surveying the United States The upper mantle of Earth is a very thick layer of rock inside the planet, which begins just beneath the crust (at about 10 km (6.2 mi) under the oceans and about 35 km (22 mi) under the continents) and ends at the top of the lower mantle at 670 km (420 mi). Temperatures range from approximately 500 K (227 °C; 440 °F) at the upper boundary with the crust to approximately 1,200 K (930 °C; 1,700 °F) at the boundary with the lower mantle.
