Geologic Processes and Landforms

This video tutorial explores geologic processes on Mars and Earth, focusing on how landforms are shaped by flowing water and lava. It includes an analysis of aerial images to study geologic changes and compares landforms formed by these processes. The tutorial also discusses how similar landforms on different planets suggest similar geologic processes, using Mars as a case study.

What are examples of geologic processes mentioned in the introduction?

• Volcanic eruptions and earthquakes

• Flowing water and wind erosion

• Tectonic shifts and sediment deposition

• Flowing water and flowing lava

What is a geologic process?

• An event that alters the biosphere

• A process that affects only the hydrosphere

• A series of events that changes the geosphere

• A single event that changes the atmosphere

What percentage of Earth's surface is covered by the hydrosphere?

• 60%

• 50%

• 80%

• 70%

What type of landform is created by flowing water?

• River channel

• Desert dune

• Mountain range

• Lava channel

What is a landform created by flowing lava called?

• Valley

• Lava channel

• River channel

• Canyon

How do landforms created by flowing lava differ from those created by flowing water?

• Water-formed landforms have no curves

• Lava-formed landforms are wider

• Water-formed landforms are straighter

• Lava-formed landforms are narrower

What is the significance of similar landforms on different rocky planets?

• They indicate different geologic processes

• They suggest similar geologic processes

• They show no relation between planets

• They are formed by atmospheric conditions

What can scientists learn by studying landforms on Earth?

• The future climate changes on Earth

• The evolution of Earth's biosphere

• The processes on other rocky planets

• The history of Earth's atmosphere

What similarities might a channel on Mars have with Earth?

• It might resemble a tectonic fault

• It could be similar to a mountain range

• It might look like a lava channel

• It could resemble a desert dune

What will be used to gather more information about the channel on Mars?

• Images from the Mars Rover

• Reports from the International Space Station

• Information from NASA

• Data from the Hubble Telescope
