Cambios en la Tierra: moldeando la superficie

The video explains how natural forces like water and ice have shaped the beautiful structures in Utah over thousands of years. It introduces the concept of weathering, where rocks and materials of the Earth's crust are broken down, and erosion, where these particles are moved to new locations. The video also describes glaciers, large masses of moving snow and ice, which contribute significantly to erosion by carrying soil, stones, and rocks, reshaping the Earth's surface.

What natural forces are primarily responsible for the process of weathering?

• Earthquakes and volcanoes

• Wind and fire

• Water and ice

• Sunlight and air

What is the main difference between weathering and erosion?

• Weathering is caused by humans, while erosion is natural.

• Weathering happens quickly, while erosion takes thousands of years.

• Weathering involves breaking down rocks, while erosion involves moving them.

• Weathering only occurs in deserts, while erosion occurs everywhere.

Which of the following is a result of erosion?

• Formation of new rocks

• Increase in Earth's temperature

• Movement of soil and rocks to a new location

• Creation of volcanic islands

What are glaciers primarily composed of?

• Salt and minerals

• Lava and ash

• Snow and ice

• Sand and gravel

How do glaciers contribute to the process of erosion?

• By blocking sunlight

• By causing earthquakes

• By carrying soil, stones, and rocks as they move

• By melting and forming rivers
