How can we gather more evidence about weather lava or water formed the channel on Mars?

How can we gather more evidence about whether lava or water formed the channel on Mars? They observe how flowing water creates channels using a stream table model, and they test ideas using the stream table model. They observe a video of a melted wax model representing how flowing lava can form a channel. Chapter 3.

Did lava or water form the channel on Mars?

“So, right here, in something that we know was formed only by flowing lava, we found most of the features that were considered to be diagnostic of water-carved channels on Mars.” The new results make “a strong case that fluid lava can produce channels that look very much like water-generated features,” says Zimbelman.

What is the evidence for water on Mars?

On the surface of Mars, the low pressure that results from the planet’s lack of a substantial atmosphere makes liquid water impossible. But scientists have long thought that there could be water trapped under Mars’s surface, perhaps a remnant of when the planet once had seas and lakes billions of years ago.

What evidence do we have that there was running liquid water on Mars in the past what evidence is there for water coming out of the ground even today?

Space missions provide us the evidence of running water on Mars in past and it is still coming out of the ground today. Space missions run by US Mariner 9, Mars Odyssey and rovers provide us the evidence of presence of water in past and coming out of the ground at present.

Is it possible that there is still liquid water on Mars today?

Pure liquid water cannot exist in a stable form on the surface of Mars with its present low atmospheric pressure and low temperature, except at the lowest elevations for a few hours.

What is the warmest it gets on Mars?

Differing in situ values have been reported for the average temperature on Mars, with a common value being −63 °C (210 K; −81 °F). Surface temperatures may reach a high of about 20 °C (293 K; 68 °F) at noon, at the equator, and a low of about −153 °C (120 K; −243 °F) at the poles.

How do I find my Mars?

Wherever you are in the world, look south for the Moon, and the little orange-red dot you see near it will be Mars.

What time can we see Mars?

Positioned against the stars of Pisces, Mars is high in the south-southeast at nightfall and will not set until 1:30 a.m. In the weeks and months to come, as Mars pulls farther away from Earth its brightness diminishes. By mid-May it has dropped to the rank of second-magnitude and it is setting before midnight.
