Answer:
C. relatively large size
Explanation:
Earth's internal heat flow to the surface is 80% due to mantle convection while the remaining heat mostly originates in the Earth's crust and about 1% due to volcanic activity, earthquakes, and mountain building.
The earth's internal heat- stresses between the lithosphere and the upper mantle are responsible
for geological processes. These stresses are the results of motions in the upper mantle stemming from convection that push the lithosphere in different directions.
Larger planets cool slower than small planets.
The acceleration due to gravity g at height 7 times the radius of Earth above the surface of the Earth is 8.933 m/s².
<h3>What is acceleration due to gravity?</h3>
It is the acceleration caused by any object when placed on the surface on the Earth due to its weight.
The acceleration due to gravity is related to the distance as
g =GM/R²
where G is the gravitational constant = 6.67 x 10⁻¹¹ N.m²/kg²
Given is the height R = 7 x 6.4 x 10⁶ m and mass of Earth M = 6 x 10²⁴ kg
Substitute the values into the expression to find the acceleration due to gravity.
g = ( 6.67 x 10⁻¹¹ x 6 x 10²⁴)/ ( 7 x 6.4 x 10⁶)²
g = 8.933 m/s²
Thus, the acceleration due to gravity g at height 7 times the radius of Earth above the surface of the Earth is 8.933 m/s².

Answer:
Psychiatrists are medical doctors, psychologists are not. Psychiatrists prescribe medication, psychologists can't. Psychiatrists diagnose illness, manage treatment and provide a range of therapies for complex and serious mental illness. Psychologists focus on providing psychotherapy (talk therapy) to help patients.
