the solid part of a rocky planet
geosphere
Key concept 1
Earth, Mars, and other rocky planets can be thought of as systems. These systems are made up of interacting spheres that can include the geosphere, atmosphere, hydrosphere, and biosphere.
Gerya
a proposed answer to a question about the natural world
claim
I am between these two planets
Earth and Jupiter
having the conditions necessary to support life
habitable
Key concept 3
Scientists can use models to test their ideas and get evidence about processes in the natural world that are difficult to observe
Dome shaped landforms on Venus
Novae
information about the natural world that is used to support or go against (refute) a claim
evidence
I am the ________ planet from the sun
4th
a feature that forms on the surface of a planet, such as a mountain, channel, or sand dune
landform
Key Concept 4
Landforms can provide evidence about the past because they remain after the geologic processes that formed them stop happening
This helped Gerya confirm his ideas about the dome shaped landforms
computer model
the process of making clear how your evidence supports your claim
reasoning
Scientists are pretty sure ________ formed the channel on my planet
water
all the liquid water and solid water (ice) on a planet
hydrosphere
Key Concept 5
Models represent the natural processes being investigated in important ways, but they are not exactly the same
Two types of models were constructed to study landforms on Mars. What were they
Water Model and the Lava Model
The most important part of a scientific argument
the reasoning
type of rock found on mars
conglomerate
: a long, narrow groove that forms where water, lava, or other liquid flows
channel
Scientists use models to...
gather evidence
a claim supported by evidence
scientific argument
This instrument was able to discover alot of details about the type of rocks and landforms on Mars
