What is a claim?
A statement that explains the answer to a question.
What is a landform?
A feature that forms on the surface of a planet, such as a mountain, channel, or sand dune
what can scientists use to help them test ideas and gather information about processes in the natural world?
A model
what is the geosphere?
The solid part of a rocky planet
Why haven't humans traveled beyond the Moon since we landed on it in the late 1960's?
Because of the size and distances between objects in outer space.
name a type of evidence to use in a scientific argument.
A Graph
An Article
A Model
An Observation
A Sample
A long narrow groove that forms where liquids flow
What are the 4 systems that make up a rocky planet?
Hydrosphere, Geosphere, Atmosphere and Biosphere
What is the Hydrosphere
all the liquid water and solid water (ice) on a planet
What are the two things a planet needs to be considered habitable?
What is a Scientific Argument
a claim supported by evidence, connected with reasoning
What is the name of the type of rock you can find a the delta of a channel formed by water?
Sedimentary Rocks
Conglomerate
Complete the sentence:
If Landforms on different rocky planets look the same, then...
those landforms were made by similar gologic processes
Name an example of systems that interact to form a channel
The Hydrosphere, Atmosphere, and Geosphere.
How can we gather more evidence about whether water or lava formed the channel on Mars?
by using models
by reading articles
by collecting samples
What is reasoning in the context of a scientific argument?
Reasoning explains how and why you chose a piece of evidence to support your claim.
How would you describe the shapes of a channel made by flowing water?
Curvey
Branching
Deep
Winding
Why are landforms important when trying to answer the question "was this planet habitable in the past?"
because they remain after the process that formed them has stopped.
An event or series of events that cause changes in the geosphere
How can we search for evidence that other planets were once habitable?
by creating a scientific argument to answer the question "what made the channel on mars?"
How could you use pictures of a channel on earth as evidence to support the claim "the channel on mars was made by flowing water?"
by comparing the shapes of both channels and finding similar shapes or features between them
What is the name of the process that breaks down rocks into smaller parts?
Weathering or Erosion
