A landslide is the movement of rock, earth, or debris down a slope due to gravity.

Planting trees helps hold the soil together with their roots, reducing soil movement.

A volcano is an opening in the Earth's surface where hot materials like lava, ash, and gases can escape.

During a volcanic eruption, lava, ash, and gases are expelled from the volcano.

An earthquake is the shaking of the ground caused by the movement of large masses of rock beneath the Earth's surface.

Earthquakes are caused by the movement of tectonic plates and the release of energy in the Earth's crust.

A forest fire is an uncontrolled fire that spreads through forested areas, often caused by lightning or human activity.

Safety measures include following fire safety rules, not leaving campfires unattended, and being prepared to extinguish fires.

Volcanic eruptions can release toxic gases and ash into the air, affecting air quality and climate.

A tsunami is a series of large ocean waves caused by underwater earthquakes or volcanic eruptions.
