Front

What are rocky planets made up of?

Back

Rocky planets like Earth and Mars can be thought of as systems made up of interacting spheres.

Front

What can landforms provide evidence about?

Back

Landforms can provide evidence about the past because they remain after the geologic processes that formed them stopped happening.

Front

Which geologic process is NOT a claim for the formation of channels on Mars?

Back

An earthquake created the channel on Mars.

Front

True or False: Similar landforms on different rocky planets suggest they may have been formed by the same geologic process.

Back

True.

Front

What two elements are necessary for a planet to be habitable?

Back

Water and a source of energy.

Front

Define 'geologic process'.

Back

Geologic processes are natural events that shape the Earth's surface, such as erosion, sedimentation, and volcanic activity.

Front

What is the significance of models in geology?

Back

Models represent natural processes being investigated and help scientists test their ideas about geologic phenomena.

Front

What is the role of flowing water in Martian geology?

Back

Flowing water is believed to have created channels on Mars, indicating past water activity.

Front

What evidence do scientists look for to understand Mars' past?

Back

Scientists look for landforms and geological features that provide clues about past processes on Mars.

Front

What is a 'habitable zone'?

Back

A habitable zone is the region around a star where conditions may be right for liquid water to exist on a planet's surface.
