Imagine that scientists have found a planet with an outer layer divided into plates made of hard, solid rock, but the mantle below the plates is made of hard, solid rock instead of soft, solid rock as it is on Earth.

Do you think plate motion would take place on that planet? Why or why not?

Answers

No because the way the plates move is because earth has soft rock under the surface

The layer of planets is made of crust, mantle, and core. The tectonic plate motion on the newly found planet will not occur as it has a hard and solid mantle.

What are tectonic plates?

Tectonic plates are defined as sold rocks that make up the mantle layer of the lithosphere of the planet. They are massive and irregular in shape that can move under high pressure and temperature conditions to form mountains and landscapes.

The plate tectonic of the planet is composed of hard, solid rock that will not be able to move or solid like that of Earth as they are hard enough to show the movement of sliding over each other unlike the soft, solid rock of Earth's lithosphere.

Therefore, the plate tectonic of the planet with hard, solid rocks will not show any movements.

**Explain your thinking below using quotes from the text.**
~You will get reported if you answer with something else~

Answers

Answer:

The freezing point of a substance is the same as that substance's melting point. At this particular temperature, the substance can exist as either a solid or a liquid. At temperatures below the freezing/ melting point, the substance is a solid.

Explanation:

edge 2021

Answer: The relationship between freezing point and melting point is that freezing point is at the temperature of when a liquid freezes and melting point is at the temperature when a solid melts which are both at the same temperature

Some quotes from the text to support this is that: "Freezing point is the temperature at which a liquid freezes and melting point is the temperature at which a solid melts.

Blink your eyes. Was work done? Explain your answer in 1 paragraph.

Answer:

Yes work was done because it takes many muscles to blink. I didn't put it in a paragraph bc I already answered this once.

Explanation:

Okay So Blink your eyes. Was work done? Explain your answer.
I don't need you telling me this isn't a real question also I need this kind of work so please don't put anything that isn't useful for my assignment .

In physics, work is defined as a force causing the movement—or displacement—of an object. In the case of a constant force, work is the scalar product of the force acting on an object and the displacement caused by that force. Though both force and displacement are vector quantities, work has no direction due to the nature of a scalar product (or dot product) in vector mathematics. This definition is consistent with the proper definition because a constant force integrates to merely the product of the force and distance.

Answers

Answer:

no work was needed. Blinking does not require using energy sometimes we blink without thinking.

Explanation:

Answer:

Yes work was done because muscles in your body contract and relax to make you move and blink. To just smile you use 32 or 36 muscles. The simplest movements are also sometimes to most complex.
