Answer:
The portion of earth underneath the crust containing the asthenosphere and mesosphere is outer core and inner core .
Explanation:
The outer core of the earth is ball of very hot metals . Its temperature is hot enough to melt all metals into liquid state . This is mainly composed of the melted metals nickel and iron . This has got got temperature between 4000 degrees to 9000 degrees .
Inner core is underneath the outer core ,Here the pressure is too high and this makes the metals squeezed and not even able to move like liquid . They are forced to vibrate just like a solid . This has got a thickness of 800 miles . The pressure here is comparably 3,000,000 times the air pressure at sea level.
Deposition:
- when a gas changes directly to a solid
- latent heat is released
- physical change, NOT a chemical change
Answer:
21
Explanation: its actually 20.85 but i guess they round to 21
Answer:
Pascal's law says that pressure applied to an enclosed fluid will be transmitted without a change in magnitude to every point of the fluid and to the walls of the container.
Explanation:
The pressure at any point in the fluid is equal in all directions.
