Answer:

Option (D)

Explanation:

The heat plays the most important role that forms the convection current in the mantle.

According to the universally accepted plate tectonic theory, The earth's crust is comprised of numerous plates, both large and small. These plates are of 2 types, commonly termed as the continental and oceanic plate.

These plates are constantly in motion because of the formation of the convection current in the mantle. This current forms due to the heat supplied by the interior of the earth.

This heat allows the convection current to form in the mantle, forcing the plates to move over the less dense, viscous layer of asthenosphere.

Thus, the correct answer is option (D).

Compare and contrast 10kg of melting ice and 1kg of freezing water address temperature heat flow thermal energy what is the simp
iris [78.8K]

Answer:

10 kg of ice will require more energy than the released when 1 kg of water is frozen because the heat of phase transition increases as the mass increases.

Explanation:

Hello!

In this case, since the melting phase transition occurs when the solid goes to liquid and the freezing one when the liquid goes to solid, we can infer that melting is a process which requires energy to separate the molecules and freezing is a process that releases energy to gather the molecules.

Moreover, since the required energy to melt 1 g of ice is 334 J and the released energy when 1 g of water is frozen to ice is the same 334 J, if we want to melt 10 kg of ice, a higher amount of energy well be required in comparison to the released energy when 1 kg of water freezes, which is about 334000 J for the melting of those 10 kg of ice and only 334 J for the freezing of that 1 kg of water.

Best regards!

A device that does work with only one movement and changes the size or direction of a force is a(n) ____.
worty [1.4K]

Answer:

A device that does work with only one movement and changes the size or direction of a force is a simple machine.

Explanation:

  • For applying force, any used basic mechanical devices are simple machines.
  • Simple machine changes the direction as well as the amplitude of the applied force i.e. we can increase or decrease the magnitude of the force.
  • A simple machine is the most basic mechanism to use the force as we need in big mechanical machines.
  • Some of the examples of simple machines are inclined plane, lever, wedge, wheel and axle, pulley, and screw.
