Erosion, Weathering, and Earth Changes

The video explores how Earth's surface is constantly changing through quick events like volcanoes and earthquakes, and slow processes like weathering and erosion. Volcanoes form landforms by erupting molten rock, while earthquakes result from tectonic plate movements, sometimes creating mountains. Weathering breaks down rocks slowly, and erosion carries them away, altering landscapes over time. These natural processes shape our planet, often with dramatic and sometimes dangerous consequences.

What are some examples of quick changes to Earth's surface?

• Volcanoes and earthquakes

• Weathering and erosion

• Mountain formation

• Ocean currents

What is a volcano?

• A type of weathering

• A landform created by molten rock erupting

• A type of earthquake

• A large body of water

How does volcanic soil benefit the environment?

• It creates new mountains

• It causes landslides

• It is rich and supports new plant growth

• It prevents erosion

What causes an earthquake?

• Volcanic eruptions

• Strong winds

• Sudden movement of tectonic plates

• Heavy rainfall

How are mountains formed?

• By erosion

• By tectonic plates pushing the ground upward

• By volcanic eruptions

• By weathering

What is weathering?

• The eruption of a volcano

• The breaking down of rocks by natural forces

• The movement of tectonic plates

• The formation of mountains

How does erosion differ from weathering?

• Erosion is caused by earthquakes

• Erosion involves the movement of broken rock pieces

• Erosion is slower than weathering

• Erosion only occurs in deserts

What can cause soil erosion to be a problem for farmers?

• It increases plant growth

• It creates new landforms

• It carries away dirt, leaving roots exposed

• It enriches the soil

What natural events can cause sudden changes to the land?

• Weathering and erosion

• Volcanoes and earthquakes

• Mountain formation

• Rain and wind

How do weathering and erosion change the Earth's surface?

• They are caused by human activity

• They only affect mountains

• They work slowly over time

• They cause immediate changes
