Geological Changes and Landforms

The video tutorial introduces second graders to the concept of changing landforms, focusing on cliffs and how they change over time due to natural forces like wind and water. It emphasizes the use of diagrams and models to visualize these changes and encourages students to think critically about the factors causing these transformations. The lesson includes activities for students to engage with the material, such as creating diagrams and comparing different landforms.

What are landforms primarily made of?

• Rock

• Water

• Soil

• Sand

Which natural elements can cause rocks to change shape over time?

• Wind and water

• Gravity and magnetism

• Sunlight and shadow

• Fire and ice

What is the purpose of using diagrams in geology?

• To create art

• To visualize changes

• To measure distances

• To predict weather

In the water cup diagram, what could have caused the water level to decrease?

• Boiling

• Freezing

• Condensation

• Evaporation

What does the flagpole and cliff diagram illustrate?

• The change in cliff shape

What is a key factor in changing the shape of an arch in the ocean?

• Water

• Earthquakes

How does water affect the shape of a valley over time?

• It makes the valley narrower

• It makes the valley shorter

• It makes the valley wider

• It makes the valley taller

What is a similarity between arches and valleys?

• Both are found in deserts

• Both have water running through them

• Both are man-made

• Both are made of sand

What is the shape of an arch landform?

• A circle

• A straight line

• A square

• An upside-down U

What can cause the sides of a valley to become taller?
