Question

Question 5

Scientists have discovered that the inner core of Earth is a solid while the outer core is a liquid. What is the cause of this observation?

-The outer core has a higher temperature and more pressure than the inner core
-The outer core has a lower temperature and lower pressure than the inner core
-The inner core has a lower temperature and higher pressure than the outer core
-The inner core has a higher temperature and lower pressure than the outer core

Question 6
Scientists have discovered convection currents inside Earth. Explain how these convection currents move and what layer(s) they occur in.

Answer 1

The reason why the inner core of planet Earth is a solid while the outer core is a liquid is because: B. The outer core has a lower temperature and lower pressure than the inner core.

Earth refers to one of the planetary bodies that rotates on its axis and revolves around the Sun in slightly elliptical orbits.

Generally, Earth comprises four (4) distinct layers starting at the center and these include;

The inner core.

The outer core.

The mantle.

The crust.

The inner core is the deepest layer of planet Earth and a solid while the outer core is a liquid.

One of the strategies used by scientists to learn about Earth's deepest layers, inner and outer structure is by recreating high-pressure conditions in a laboratory.

According to these experiments conducted by scientists on planet Earth, the pressure in the inner core is immense and over three (3) million times greater than the pressure on Earth’s outer core.

In conclusion, the inner core has a higher temperature and higher pressure than the outer core of planet Earth, thereby, making the inner core of planet Earth is a solid while the outer core is a liquid.

Step-by-step explanation:

Answer 2

Question 5: The outer core has a lower temperature and lower pressure than the inner core

This is because the outer core is not as hot as the inner core. It is also under slightly less pressure. Due to this, the outer core is liquid and less dense than the inner core.

Question 6: I'm not sure what the answer to that is.. but I believe you'll figure it out!
