- What is an earthquake?
An earthquake is a sudden shaking or trembling of the ground caused by the movement of tectonic plates beneath the Earth's surface. This movement releases energy in the form of seismic waves.
- What is a volcano?
A volcano is a mountain or opening in the Earth’s crust that allows hot lava, ash, and gases to escape from below the surface. It forms when magma rises from deep within the mantle and erupts through the crust.
- How does an earthquake change the surface of the earth?
An earthquake can crack the ground, cause landslides, collapse buildings, shift land masses, and even alter the course of rivers. It can create new faults or widen existing ones, changing the landscape dramatically.
- How does a volcano change the surface of the earth?
A volcano changes the Earth’s surface by building up new land with lava flows and ash deposits. Over time, repeated eruptions can form mountains, islands, or plateaus. Volcanic activity can also reshape valleys, bury landscapes, and alter soil composition.
