Earth's Interior Graphs and Density

Front

What is the approximate depth if the pressure is 2.0 million atmospheres?

Back

4000 km

Front

What is the inferred temperature at the interface between the stiffer mantle and the asthenosphere?

Back

2500°C

Front

What is the approximate temperature at a depth of 1,500 km?

Back

3,300 Degrees Celsius

Front

What are the inferred temperature and pressure of Earth’s interior at a depth of 3,000 kilometers?

Back

5000°C and 1.5 million atmospheres

Front

What is the pressure at the interface between Earth’s outer core and inner core?

Back

3.1 million atmospheres

Front

Define the asthenosphere.

Back

The asthenosphere is a semi-fluid layer of the Earth's mantle located below the lithosphere, which allows for the movement of tectonic plates.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and the uppermost part of the mantle.

Front

Explain the relationship between depth and pressure in Earth's interior.

Back

As depth increases within the Earth, pressure also increases due to the weight of the overlying rock.

Front

What is the temperature range in the Earth's interior?

Back

The temperature in the Earth's interior can range from about 1000°C near the surface to over 5000°C in the inner core.

Front

What is the significance of the outer core?

Back

The outer core is liquid and is responsible for generating Earth's magnetic field through the movement of molten iron.
