Earth 2.0 LEQ 3 and 4

Front

What is the composition of the outer core of the Earth?

Back

The outer core is composed of liquid iron and nickel.

Front

Why does the inner core remain solid despite being extremely hot?

Back

The inner core is solid due to the immense pressure from the layers above it.

Front

What are the primary elements that make up the Earth's core?

Back

The core is primarily made up of nickel and iron.

Front

What layer does the lithosphere float on?

Back

The lithosphere floats on the asthenosphere.

Front

What is the yellow layer in the Earth's compositional layers?

Back

The yellow layer represents the mantle.

Front

What is the lithosphere composed of?

Back

The lithosphere is composed of the crust and the uppermost part of the mantle.

Front

What is the state of matter of the outer core?

Back

The outer core is in a liquid state.

Front

What is the significance of the asthenosphere in plate tectonics?

Back

The asthenosphere allows for the movement of tectonic plates due to its semi-fluid nature.

Front

How does pressure affect the state of materials in the Earth's interior?

Back

Increased pressure can cause materials to become solid, as seen in the inner core.

Front

What is the temperature range of the Earth's inner core?

Back

The temperature of the inner core is estimated to be between 4,000 to 5,500 degrees Celsius.
