Question

Describe the following terms
(i)volcanic core
(i)caldera
(iii)geyser

Answer 1

Answer:

(i) volcanic core ;-Deep down inside the center of the earth, lies a solid mass known as the inner core. This inner core is hot – very hot – so hot that it is actually melted rock. But because of its location, this melted rock is pressed by the weight of all of the layers above it, into a solid mass.

(ii) caldera ;-A caldera is a volcanic feature formed by the collapse of a volcano into itself, making it a large, special form of volcanic crater. A caldera collapse is usually triggered by the emptying of the magma chamber beneath the volcano, as the result of a large volcanic eruption.

(iii) geyser ;-A geyser is a vent in Earth's surface that periodically ejects a column of hot water and steam. Even a small geyser is an amazing phenomenon; however, some geysers have eruptions that blast thousands of gallons of boiling-hot water up to a few hundred feet in the air. Old Faithful is the world's best-known geyser.
