Which three events occur when Earth's convection currents move toward each other?

Tectonic plates above the currents move toward each other.

Magma emerges from Earth's interior, forming new crust.

One plate will submerge beneath another plate.

A convergent boundary is formed at the site of the collision.

The flow of magma stops, but only temporarily.

The correct answers are:

- Tectonic plates above the currents move toward each other;

- One plate will submerge beneath another plate;

- A convergent boundary is formed at the site of the collision;

The convection currents are the ones responsible for the movement of the tectonic plates, thus shaping the Earth's appearance with their movement, as well with the structures created by the movement. If the convection currents move toward each other, than the tectonic plates are moving toward each other. That will cause collision between the continents, and convergent boundaries will be formed. If the collision is between two or more continental plates, than they will merge, and from the pressure mountain ranges will start to form, but if there an oceanic plate involved as well, than the oceanic plate will be subducting beneath the continental plate or plates.

Option A, Tectonic plates above the currents move toward each other.

Option C, One plate will submerge beneath another plate.

Option D, A convergent boundary is formed at the site of the collision.

Explanation:

The convection currents are produced with in deep earth surface when the hot mantle rise and fall continuously and rapidly thereby causing radioactive decay of core of earth.

Due to this movement with in the core, the following occurs -

a) Movement of plate - either convergence or divergence near the earth crust. This movement of plates is called Plate Tectonic

b) Volcanoes and earthquake occurs due to tectonic plate movement

c) Constructive plate margins are formed in the mid ridge region.

Hence, option A, C and D are correct
