Earth's Surface Changes and Processes

The video explores how Earth's surface changes through events like volcanoes and earthquakes, which cause rapid changes, and processes like weathering and erosion, which occur slowly over time. It explains the formation of landforms such as mountains and the impact of natural events on the environment.

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

• Volcanoes and earthquakes

• Ocean currents

• Weathering and erosion

• Mountain formation

How does volcanic soil benefit the environment after an eruption?

• It cools the surrounding area

• It creates new water sources

• It is rich in nutrients for new plant growth

• It prevents erosion

What causes an earthquake?

• Sudden movement of tectonic plates

• Strong winds

• Heavy rainfall

• Volcanic eruptions

How are mountains formed over time?

• By accumulation of sand

• By erosion of rocks

• By tectonic plates pushing the ground upward

• By volcanic eruptions

What natural event can create landslides and mudslides?

• Weathering

• Earthquakes

• Volcanic eruptions

• Erosion

Why are scientists unable to predict earthquakes and volcanic eruptions with complete certainty?

• The Earth's surface never changes

• They lack the necessary tools

• They do not study these events

• The events are too sudden and complex

What is the difference between weathering and erosion?

• Erosion breaks down rocks, weathering carries them away

• Neither affects the Earth's surface

• Weathering breaks down rocks, erosion carries them away

• Both involve the movement of rocks

How can erosion affect human structures?

• It makes them more stable

• It has no effect

• It can cause damage by removing supporting soil

• It strengthens them

What is the process called when rocks are broken down by natural forces?

• Weathering

• Erosion

• Crystallization

• Sedimentation

What is a long-term effect of erosion on the landscape?

• Formation of volcanoes

• Immediate land changes

• Creation of new mountains

• Formation of caves
