Explanations: answer key for all 10 questions

Q1: Which plates collided to form the Himalayas?
Answer: The Indian and Eurasian plates
The collision still continues.
Q2: Roughly when did the collision begin?
Answer: About 50 million years ago
Dates vary by study.
Q3: Which ancient ocean closed as India moved north?
Answer: The Tethys Ocean
Its seafloor sediments were lifted.
Q4: What was unusual about India's journey north?
Answer: It moved unusually fast for a plate
Some estimates exceed 15 cm a year.
Q5: What is found in rock near Everest's summit?
Answer: Marine fossils
The rock formed under the sea.
Q6: What type of rock forms Everest's summit?
Answer: Limestone
It is called the Qomolangma Formation.
Q7: What kind of mountains are the Himalayas?
Answer: Fold mountains
Crust buckled and stacked up.
Q8: Which high plateau also formed from the collision?
Answer: The Tibetan Plateau
It is often called the roof of the world.
Q9: Are the Himalayas still rising?
Answer: Yes, by a few millimeters a year
Erosion works against the uplift.
Q10: Which 2015 disaster showed the collision's power?
Answer: The Nepal earthquake
Stress builds where plates meet.

Himalayas Formation Quiz – Plate Collision and Rising Peaks

The Himalayas formed when the Indian plate collided with the Eurasian plate, beginning roughly 50 million years ago. India had traveled north unusually fast, closing the ancient Tethys Ocean between them.

The collision crumpled and stacked layers of crust into fold mountains. Seafloor sediments were lifted high, so limestone with marine fossils caps Mount Everest. The Tibetan Plateau rose behind the range.

India is still pushing north, and the Himalayas continue to rise by a few millimeters a year, though erosion wears them down. The stress causes earthquakes, such as the 2015 Nepal earthquake.
