Question

1. the passage mentions that the himalayas are still rising. which of the following best explains why this is happening?

a. the himalayas are situated on a transform boundary where plates are sliding past each other.
b. the ongoing collision of the indian and eurasian plates continues to exert pressure, causing the crust to buckle and fold.
c. the himalayas are experiencing uplift due to the melting of glaciers and ice sheets.
d. the himalayas are located near a divergent boundary where new crust is being formed.

1. based on the information provided in the passage, which of the following statements accurately describes the process of seafloor spreading?

a. subduction zones are the primary sites of seafloor spreading, where old crust is recycled into the mantle.
b. magma rises at mid - ocean ridges, forming new crust that pushes older crust away, renewing the ocean floor.
c. seafloor spreading occurs at transform boundaries where plates slide past each other, creating new crust.
d. oceanic plates collide at mid - ocean ridges, creating new crust and pushing older crust downwards.

1. according to the passage, how does understanding plate tectonics help in locating and managing natural resources?

Explanation:

1. The Himalayas are formed by the collision of the Indian and Eurasian plates. This ongoing collision exerts pressure causing crustal buckling and folding, leading to continued uplift.
2. Seafloor spreading occurs at mid - ocean ridges where magma rises, forms new crust and pushes older crust away.

Answer:

1. B. The ongoing collision of the Indian and Eurasian plates continues to exert pressure, causing the crust to buckle and fold.
2. B. Magma rises at mid - ocean ridges, forming new crust that pushes older crust away, renewing the ocean floor.
