Earth Science Concepts and Phenomena

The video tutorial by Tássia Reis explores geomorphology, focusing on the internal and external agents that shape the Earth's relief. Internal agents like tectonism, volcanism, and earthquakes cause rapid changes, while external agents such as weathering and erosion act slowly. The video also discusses the types of weathering—chemical, physical, and biological—and highlights human activities' impact on the Earth's surface. The tutorial concludes with a call to action for viewers to engage with the content.

What does the term 'geomorphology' refer to?

• Study of the Earth's oceans

Why are there few active volcanoes in Brazil?

• Brazil is located at the center of a tectonic plate

• Brazil has a cold climate

• Brazil is surrounded by oceans

• Brazil has frequent earthquakes

Which type of weathering involves the chemical breakdown of rocks?

• Chemical weathering

• Mechanical weathering

• Biological weathering

• Physical weathering

What is the primary cause of physical weathering in the northeastern region of Brazil?

• Frequent earthquakes

• Low temperatures

• High temperatures

• Heavy rainfall

Which type of weathering is caused by the actions of living organisms?

• Biological weathering

How do human activities such as construction and mining affect the Earth's relief?

• They only affect the ocean currents

• They have no significant impact

• They only affect the atmosphere

• They can significantly alter the landscape
