What liquid formed channels on the surface of mars long ago and what property of liquids made this possible?
The liquid that formed channels on the surface of Mars long ago is primarily water. The property of liquids that made this possible is their ability to flow and erode the landscape, which is influenced by factors such as gravity and the planet's topography. Additionally, under the right conditions, liquid water can exist in a variety of states, allowing it to shape the Martian surface through processes like erosion and sediment transport.
What are outflow channels on mars?
Outflow channels on Mars are large, wide channels that appear to have been carved by the flow of water in the distant past. They are thought to have formed as a result of catastrophic flooding events, where large volumes of water were released rapidly onto the Martian surface, creating these distinct features. The presence of outflow channels suggests that liquid water played a significant role in shaping the Martian landscape.
Was there ever been a flood on Mars?
There is evidence that Mars experienced ancient floods in its past, as seen in features such as dry river channels, valleys, and sediment deposits. Some of these suggest that large amounts of water flowed on the planet's surface billions of years ago. However, liquid water is not currently stable on the surface of Mars due to its thin atmosphere and low atmospheric pressure.
The sulfate mineral found on the surface of Mars that supports the presence of liquid water is called?
Jarosite is the sulfate mineral found on the surface of Mars that indicates the past presence of liquid water.
Why do scientist believe the surface of mars may have contained liquid water in the past?
Giant flood channels and tree-like networks of tributaries have been found on Mars. Furthermore, specific minerals such as hematite and goethite have been found, both of which sometimes form in the presence of water. Jarosite has also been found by the Opportunity lander in 2004 - this only forms in acidic water, confirming that water must have been around in the past.
Why were scientists surpised to observe recently formed liquid water channels on mars?
Mars is too cold for liquid water to flow on the planet surface
What planet has evidence of erosion by water?
Mars has evidence of erosion by water, including river valleys, channels, and minerals formed in the presence of water. Mars once had liquid water flowing on its surface, shaping the landscape over time.
What were Mars' channels caused by?
Mars' channels, also known as Martian channels or valley networks, were likely formed by catastrophic flooding events and possibly also by the release of groundwater. These channels show evidence of erosion and deposition that suggest the presence of liquid water in Mars' past. The exact mechanisms for their formation are still a topic of ongoing research and study.
How much of Mars has water?
Mars has no liquid surface water.
What is the sea surface area of Mars?
Although areas of Mars have the name "mare" (sea), there is no liquid water on the surface of Mars.
Which inner planet once had water on it?
The Rover mission confirmed that Mars once had liquid water on its surface.
Does the surface of mars have long channels from water flow?
They believe that it is from water flow.
What planet surface shows signs of water erosion?
Mars shows signs of water erosion on its surface, including features like valleys, river channels, and delta deposits. These indicate that liquid water flowed on the planet's surface in the past.
What planet is too cold for liquid water to exist on the surface.?
Mars is a planet that is too cold for liquid water to exist on its surface. Almost the entire surface of Mars is covered in ice.
Which feature on Mars point to the possibility of liquid water on the planet?
Gullies and streamlike channels
What are three discoveries made by spacecraft that have been sent to study mars?
Evidence of ancient water channels, lakes, and glaciers on Mars, suggesting the presence of liquid water in the planet's past. Identification of methane in the Martian atmosphere, hinting at potential microbial life or geological activity. Detection of diverse minerals and geological formations, providing insights into Mars' geological history and potential habitability.
