Cave Formation and Features

The video explores the fascinating world of caves, explaining their formation through various natural processes. Solution caves form when rainwater, containing acid, dissolves rocks like limestone. Sea caves are created by ocean waves eroding the shoreline. Volcanic activity can lead to lava caves and tubes. Other forces like earthquakes, glaciers, and wind also contribute to cave formation. Caves offer a unique glimpse into Earth's interior.

What is a cave?

• A natural opening in the ground with a hollow space

• A small hole in a tree

• A man-made tunnel

• A type of mountain

How are solution caves primarily formed?

• By the movement of tectonic plates

• By volcanic eruptions

• By the action of wind

• By acidic rainwater dissolving certain rocks

Which type of rock is NOT typically dissolved to form solution caves?

• Granite

• Gypsum

• Marble

• Limestone

What are stalactites?

• Rock formations that rise from the floor of a cave

• Rock formations that hang from the ceiling of a cave

• Mineral deposits found in rivers

• Columns of ice found in caves

How do stalagmites form?

• By water dripping from the ceiling and evaporating

• By wind erosion

• By volcanic activity

• By the accumulation of sand

What natural force is responsible for creating sea caves?

• Wind

• Earthquakes

• Volcanic eruptions

• Ocean waves

What is a lava tube?

• A cave formed by wind erosion

• A tunnel formed by flowing lava

• A type of sea cave

• A cave formed by glacial movement

Which of the following is NOT a way caves can be formed?

• By wind

• By human excavation

• By earthquakes

• By glaciers

Why are caves considered unique landforms?

• They provide a view into the interior of our planet

• They are always man-made

• They are always filled with water

• They are only found in deserts
