An earthquake shakes a snow-covered mountain. The fresh snow slides down. It's an avalanche!
Wind blows dry, tall grass. A storm brews. Lightning strikes the ground, and soon, flames spread across the grassland. It's a wildfire!
Hot magma rises to the earth's surface. Smoke bursts from the volcano and lava flows out. It's a volcanic eruption!
Water rushes out to sea out of nowhere. Suddenly, huge waves come crashing inland. It's a tsunami!
