How do erupting volcanoes change landforms?
A. Erupting volcanoes become flat and form plateaus.
B. Hot lava erodes rocks and makes mountains smaller.
C. Cooled lava forms layers of rock that can become islands.
D. Cooled lava forms soil that supports animal and plant life on plains.
C. Cooled lava forms layers of rock that can become islands.
C. Cooled lava forms layers of rock that can become islands.
The correct answer is C. Cooled lava forms layers of rock that can become islands.
Erupting volcanoes can lead to various changes in landforms. When a volcano erupts, it releases hot lava, ash, and gases. The hot lava, when it cools down and solidifies, forms layers of rock known as volcanic rock or volcanic tuff.
These layers of volcanic rock can accumulate over time and become quite extensive. In some cases, they can even build up to form volcanic islands. The Hawaiian Islands are a prime example. They are a chain of volcanic islands formed by successive eruptions of underwater volcanoes. As the lava cools and solidifies, it adds to the height and size of the island.
Therefore, the correct answer is C. Cooled lava forms layers of rock that can become islands.
