Question

our scientific question
what geologic process could have formed the channel on mars?
we have been thinking about two claims that are possible explanations for how the channel on mars was formed. we have considered evidence from images, as well as from the flowing water model and the flowing lava model. as you answer the questions below, refer to the image of the channel on mars on page 17.

1. select the claim you think is best supported by the evidence you have seen so far. (check one)

□ claim 1: flowing water formed the channel on mars.
□ claim 2: flowing lava formed the channel on mars.

1. why do you think the claim you selected is best supported by the evidence?

Explanation:

There is no evidence provided in the question - text to make a definite choice. However, in general, flowing water can create channels with features like smooth - bottomed and meandering shapes, while flowing lava can create channels with different textures and shapes related to its high - temperature and viscous nature. If there are features like sediment deposits or rounded pebbles in the image (not shown here), it may support the water claim. If there are features like rough, volcanic - rock lined channels or lava flow patterns, it may support the lava claim.

Answer:

1. Without seeing the evidence, cannot select a claim.
2. Without a selected claim, cannot provide a reason for support.
