Geologic Processes on Mars

Which of the following is NOT a type of landform that can be formed by flowing water or lava?

• Channels

• Volcanoes

• Sand dunes

• Canyons

Which of these geologic processes on Earth could have also occurred on Mars in the past?

• Plate tectonics

• Erosion

• Glaciation

• All of the above

What is the main reason that scientists study satellite images and data from Mars?

• To determine if Mars could have supported life in the past

• To create a detailed map of the Martian landscape

• To find evidence of current volcanic activity on Mars

• Both a and b

According to the lesson, what is one way that scientists can determine if Mars was once more habitable?

• Analyzing the chemical composition of the Martian atmosphere

• Searching for evidence of past liquid water on the Martian surface

• Measuring the average temperature on Mars

• All of the above

Which of these is the best definition of a "geologic process"?

• An event or series of events that causes changes in the geosphere

• A feature that forms on the surface of a planet, like a mountain or sand dune

• A type of landform created by flowing water or lava

• A method used by scientists to study the geology of other planets

Which of the following is NOT a piece of evidence that scientists can use to determine if Mars was once more habitable?

• Analyzing satellite images of the Martian surface

• Studying the chemical composition of Martian soil samples

• Measuring the current average temperature on Mars

• Observing the presence of tectonic plate movement

How does the lesson define the term "landform"?

• A feature that forms on the surface of a planet, such as a mountain or sand dune

• An event or series of events that causes changes in the geosphere

• A type of rock or mineral found on the surface of a planet

• A method used by scientists to study the geology of other planets

Which of these geologic processes would most likely form a wide, straight channel on a planet's surface?

• Flowing water

• Flowing lava

• Wind erosion

• Volcanic eruptions

Why do the lesson and activity focus on comparing landforms on Mars to those on Earth?

• To show that Mars and Earth have the same types of geological features

• To determine if there is any evidence that Mars could have once been more habitable

What key concept does the lesson emphasize about comparing landforms on different planets?

• Landforms that look similar on different planets were likely formed by the same geologic process

• Landforms that look different on different planets could not have been formed by the same process

• Landforms can only provide evidence about the past geography of the planet where they are located

• Landforms on other planets cannot be directly compared to those on Earth
