an object, diagram, or computer program that helps us understand something by making it simpler or easier to see
What is a model?
Geosphere, atmosphere, hydrosphere and biosphere are all interacting parts of systems for these planets
What is Mars, Earth and other rocky planets?
Mountains
What is the geosphere?
Strange landforms scattered around Venus
What are novae?
any planet with a solid surface, such as Earth or Mars
What is a rocky planet?
When landforms on different rocky planets look similar, it is evidence of this.
What is geologic process?
Ice caps
What is the water sphere?
Melted rock rises up from underground, pushing the surface upward and creating novae.
What did the Venus computer model show?
having the conditions necessary to support life
Computer programs are examples of what scientists use to test their ideas about the natural world that are difficult to observe.
What is a model?
Bacteria
What is biosphere?
462 degrees Celsius or 861 degrees Farenheit.
a feature that forms on the surface of a planet, such as a mountain, channel, or sand dune
What is a landform?
These provide evidence about the past because they remain after the geologic processes that formed stopped happening.
What are landforms?
Carbon Dioxide
What is the atmosphere?
The top layer of rock is thinner than Earth's top layer of rock
What is Venus?
an event or series of events that causes changes in the geosphere, such as flowing water or flowing lava
What is geologic process?
Something that represents the natural processes being investigated but they are not exactly the same.
What are models?
The channel on Mars
