Answers

Last one a cheetah races

The statement that best describes the life characteristic of movement is human skin and lungs release carbon dioxide.

What do you understand by movement?

Movement is an action of moving of any thing from one part or place to another part.

Life characteristic of the movement is shown by the human skin and lungs as skin opens and closes their pores time to time for the removal of gases and lungs also contracts and expands for the conversion of oxygen into carbon dioxide.

Hence, human skin and lungs release carbon dioxide is the life characteristic of movement.

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.

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.
