Question

(1) Earth's crust is made up of relatively rigid plates that ride atop Earth's hot, semiliquid mantle. (2) The plates are called tectonic because they're in constant motion. (3) They can move because Earth's mantle is a very hot and semiliquid fluid called magma. (4) Volcanoes are a result of magma rising up or erupting through a plate, particularly where plate boundaries are moving against each other. (5) Also, when plates slide against each other, causing friction along adjacent plate boundaries, earthquakes frequently occur. (6) Therefore, we often find volcanoes and earthquakes along plate boundaries. (7) Plates may also collide. (8) When that happens, mountain ranges are formed. (9) For example, the collision of the plate carrying the Indian subcontinent created the Himalayan Mountains when it collided with the Asian plate. Which statement about this paragraph is accurate?

Answer 1

2 and 4 both make true statements

Answer 2

Option (2), (4), (5), (6) and (9)

Step-by-step explanation:

The earths's crust is comprised of numerous small and large plates known as the lithospheric plates or the tectonic plates, and this plates are constantly in motion over the hot dense and viscous asthenosphere.

This plate motion takes place in three different ways, such as-

• Convergent plate movement- here two plates moves towards each other.
• Divergent plate movement- here two plates moves away from each other.
• Transform plate movement- here two plates slide past one another.

Due to the collision between oceanic and continental plates, the denser plate gets subducted and undergoes partial melting as a result of which the magma forces to come out to the surface forming volcanoes.

The areas that are near to this plate boundaries frequently experiences earthquakes and volcanic eruptions depending upon its intensity.

Due to the collision between the Indo-Australian plate and the Eurasian plate, the Indo-Australian plate being more dense getting subducted forming the great Himalaya mountains.

Thus, the most accurate option are (2), (4), (5), (6) and (9).
