How do you know when the transfer of heat (thermal energy) has ended?

What process, driven by heat generated from within the Earth's core, occurs in the mantle and is a primary cause of plate tectonics?A.faulting
B.mantle convection
C.subduction
D.trench formation

Answers

Answer:

The correct option is (B)mantle convection

Explanation:

Tectonic plates at the earth's surface move because of the intense heat in the Earth's core. this heat causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell and producing a movement called mantle convection which is the slow creeping motion of Earth's solid silicate.
The answer is B. Mantle convection.

What effect does distance have on the force of gravity?A - Increasing the distance between two objects increases the gravitational force.

B - Decreasing the distance between two objects decreases the gravitational force.

C - Increasing the distance between two objects decreases the gravitational force.

D - Distance is not a factor in determining the force of gravity.

Answers

The effect does distance have on the force of gravity is increasing the distance between two objects decreases the gravitational force. Therefore, option C is correct.

What is gravitational force ?

The gravitational force, which is what pushes mass-containing objects toward one another. We frequently consider the pull of gravity from the Earth. Your body is kept on the ground by this force. However, all mass-bearing objects are pulled toward one another by gravity.

Any two mass-containing objects are attracted to one another by the gravitational force. Because it consistently attempts to pull masses together rather than pushing them apart, the gravitational force is known as attractive.

According to legend, Isaac Newton developed the theory of gravitation around 1665 or 1666 after observing an apple fall and wondering why it fell straight down rather than sideways or even upward.

Thus, option C is correct.

What is the direction of transfer of energy in the waves produced?

Answers

Transverse waves occur when a disturbance causes oscillationsperpendicular (at right angles) to the propagation (the direction of energy transfer). Longitudinal waves occur when the oscillations are parallel to the direction of propagation.

Transverse waves occur when a disturbance causes oscillations perpendicular
