Question

How does convection in Earth's mantle affects the formation of landmass like
olcano and mountain?
A. Heat tries to escape in the interior of the earth.
B. Collision and separation of tectonic plates happens due to the slow
motion of convection cells.
C. When warm material in the mantle rises up to the surface (ground), it
will cool and sinks, these cooled materials will eventually be turned into
landmass.
D. All of the above​

Answer 1

Answer:

d fam.

Explanation:

when beat tries to escape it makes underwater vents it the sea bed. tectonic plates make mountains. it has to be d

Answer 2

Convections in Earth's mantle affects the formation of landmasses like volcano and mountain by:

A. Heat tries to escape in the interior of the earth.

B. Collision and separation of tectonic plates happens due to the slow motion of convection cells.

C. When warm material in the mantle rises to the surface (ground), it

will cool and sink, these cooled materials will eventually be turned into

a landmass.

All of the above statements are correct.

What is the tectonic plate theory?

• The tectonic plate theory states that "the Earth's outer crust-the Lithosphere- is made up of many tectonic plates, which have been moving slowly since 3.4 billion years ago."
• The movement of the plates can be convergent, divergent, or transform.
• Depending on the type of movement, volcanic eruptions, mountains, oceanic trenches, etc. are formed.

How do the convection currents affect the tectonic plates?

• A convection current is formed when a hot fluid rises upwards as its density decreases, forcing the cooler part to move downwards.
• In Earth's core, magma heats up and moves upwards. Once it reaches the mantle, it pushes against the tectonic plates.
• At the top of the mantle, the magma starts moving down again, but before that, it forces the tectonic plates to move horizontally in a particular direction.
• These convection currents move the tectonic plates very slowly.
• The movement of these plates lead to volcanic eruptions, the formation of mountains, tsunamis, etc.

Now, let us explain the process using the options given:

A. Heat tries to escape in the interior of the earth.

• When the core of the Earth generates heat, it tries to escape.
• It heats the magma, which moves upward due to convection.

B. Collision and separation of tectonic plates happens due to the slow

the motion of convection cells.

• As the magma moves upward due to convection, it pushes up against the tectonic plates, causing their horizontal movement.
• The plates may move sideways or separate. This will happen at a very slow rate as the plates are extremely large.

C. When warm material in the mantle rises to the surface (ground), it

will cool and sink, these cooled materials will eventually be turned into

landmass.

• As the magma reaches the mantle, it starts to cool and sink again, but it causes changes in the position of the tectonic plates before sinking.
• Depending on the type of movement of the plates, landmasses will be formed.

Hence, from the explanation stated above, we can conclude that option D. All of the above is correct.
