Question

1. base your answer to the following question on the map below. the map represents the movement of tectonic plates that resulted in the collision of india with asia. scientists believe that 71 million years ago, india was at position a.

map of indias movement over time relative to asia, with positions marked at 71 million, 55 million, 38 million, and 10 million years ago
which present - day geologic feature in nepal resulted from this collision?
(1) a mountain range
(2) an oceanic ridge
(3) a rift valley
(4) an oceanic trench

1. the tonga trench is located at which type of plate boundary?

(1) transform
(2) convergent
(3) complex
(4) divergent

Explanation:

Question 1

The collision of the Indian plate (India) with the Eurasian plate (Asia) is a convergent plate boundary interaction. Such collisions typically form mountain ranges due to the compression and uplift of the crust. Nepal is home to the Himalayan mountain range, which formed from this collision. Oceanic ridges form at divergent boundaries, rift valleys at divergent or continental rift zones, and oceanic trenches at convergent boundaries where an oceanic plate subducts (not the case here as both India and Asia are continental plates in this collision). So the correct feature is a mountain range.

Tonga Trench is formed where the Pacific plate (oceanic) subducts beneath the Tonga plate (oceanic), which is a convergent plate boundary (specifically an ocean - ocean convergent boundary). Transform boundaries involve sliding past each other, divergent boundaries involve plates moving apart, and "complex" is not a standard plate boundary type. So the Tonga Trench is at a convergent boundary.

Answer:

(1) a mountain range
