How do temperature, pressure, and density impact the core of Earth?

The asthenosphere is semi-fluid and always in motion. This movement is caused by the heat in Earth and creates convection currents. Convection currents are circular movements based on temperature and density. The heat from deep inside Earth heats up the semi-fluid particles of the asthenosphere. These particles then become less dense and rise. As they rise to the bottom of the crust, they cool off, become denser, and move back toward the core. Back at the core, their temperature will increase again, causing this circular motion to continue.

Convection currents in the asthenosphere cause movement of Earth's tectonic plates. The crust, though rigid, is broken into a series of tectonic plates that fit together like pieces of a puzzle. The plates float on the semi-fluid asthenosphere and move around in predictable directions. It's like a giant conveyor belt moving molten material from one place to another and causing the plates that float on top to slide to new locations.

Explanation:

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
