How is heat transfer involved in the movement of tectonic plates?

Simora [160]

Mantle convection

Explanation:

The driver of moving plates is the mantle convection.

Convection is a heat transfer process that involves the movement of fluids from one place to another.

How does convection occur in the mantle?

Part of the mantle known as the asthenosphere is a hot liquid. It moves slowly and does not readily flow.
Over riding the asthenosphere is the brittle lithosphere made up of the upper mantle and the entirety of the crust.
The asthenosphere is at a higher temperature compared to the lithosphere on top.
In order to achieve stability and thermal equilibrium, the asthenosphere rises to the surface whereas the dense and cold lithosphere sinks down.
This way a convective cell is set up.
Hot materials rises to the surface because they are light whereas cold materials on the surface sinks into the asthenosphere.
Through this the plates moves.

A "sun yacht" is a spacecraft with a large sail that is pushed by sunlight. Although such a push is tiny in everyday circumstanc

guajiro [1.7K]

Answer:

acceleration = 0.022 m/s^2

distance = 8.3 x 10^7 m

speed = 1.9 x 10 ^3 m/s

Explanation:

the parameters given are:

mass = 900kg

force = 20N

from the formula force = mass x acceleration

acceleration = force / mass

acceleration = 20 / 900

acceleration = 0.022 m/s^2

distance travelled in 1 day (86,400 seconds) = (1/2) x a x t^2

(1/2) x 0.022 x (86,400^2) = 8.3 x 10^7 m

speed of the sun yatch (v) = a x t

0.22 x 86400 = 1.9 x 10 ^3 m/s

Helga [31]

The process which involves plants to cause weathering to a seed that falls into a crack in a rock therefore, breaking apart the rock is called Mechanical weathering.

<h3>Mechanical weathering</h3>

This is defined as the set of weathering processes that break apart rocks into particles (sediment) through physical processes. The most common form of mechanical weathering is the freeze-thaw cycle. Water seeps into holes and cracks in rocks then the water freezes and expands, therefore making the holes larger eventually making the rock split apart.
