Two Martian features that suggest water once existed on its surface are valley networks and outflow channels. Valley networks resemble river systems on Earth, indicating that liquid water may have flowed across the surface, carving these formations. Additionally, outflow channels, which are large, wide depressions, suggest that massive amounts of water were released rapidly, likely from melting ice or subsurface reservoirs, further supporting the presence of water in Mars' past.

What features on mars point to possibility of water?
Features such as dried-up river channels, outflow channels, and sedimentary rocks suggest the past presence of water on Mars. Additionally, the discovery of hydrated minerals and ice deposits further support the idea that water once flowed on the Martian surface.
What is the purpose of the exploration of Mars?
To study and explore the Martian surface, atmosphere, and general conditions.
Does Callisto have any volcanoes?
No, Callisto does not have any active volcanoes. Its surface features primarily consist of impact craters, as well as some subtle volcanic features such as calderas and domes that suggest past volcanic activity.
What are 3 noticeable features that are found on the surface of mercury?
Three noticeable features found on the surface of Mercury are vast impact craters caused by collisions with asteroids and comets, long scarps or cliffs that suggest the planet has shrunk over time, and smooth plains formed by volcanic activity.
What features on mars point to the possibility of liquid water on other planets?
Mars exhibits several features that suggest the past presence of liquid water, including ancient river valleys, lake beds, and mineral deposits such as clays and sulfates that typically form in aqueous environments. Additionally, recurring slope lineae (RSL) observed on Martian slopes may indicate seasonal flows of briny liquid water. The detection of water ice at the poles and beneath the surface further supports the idea that liquid water could have existed in the past and may still exist in some form today. These findings enhance the potential for liquid water on other planets, suggesting similar geological processes might occur elsewhere.
What planet has dry river beds?
Mars is known to have dry river beds, which are evidence of past water flow on the planet. These ancient river channels suggest that liquid water may have once existed on the Martian surface.

What did The Martian canals turned out to be?
The "Martian canals" originally thought to be evidence of a complex network of waterways were later found to be an optical illusion. These features observed by early astronomers were likely due to limitations in their equipment and interpretation of what they were seeing on the Martian surface.
What causes the changing dark and light features visible on the Martian surface from Earth?
the correct answer is highly cratered and eroded areas that are frequently covered and uncovered by dust
How strong is the Martian gravity?
At the surface, 38% of its value at the Earth's surface.
What dust covers the martian surface?
Iron oxide
What features on mars point to the possibility of liquid water on the planet?
Features such as dried-up river channels, lake beds, and mineral deposits that require water to form suggest the possibility of liquid water on Mars in the past. Recent discoveries of recurring slope lineae (dark streaks on Martian slopes) also indicate that liquid water may exist on the planet's surface today.
What aspects of the martian environment might limit or affect the scientists' ability to do this kind of work outside on the martian surface?
Mars does not have a breathable atmosphere, which makes it difficult to work on the surface.
How do Martian meteors leave Mars?
Martian meteorites were ejected from the surface of Mars during massive asteroid and comet impacts.
Why was curiosity made with six wheels?
More stability on the rocky Martian surface
What was the mission of spirit and opportunity rovers?
Oppertunity's missions are to discover new martian rocks, map mars' surface, and to help scientists learn about martian weather.
Why is the meteorite ALH84001 so important to in terms of searching life on other planets?
Allan Hills 84001 or ALH84001 is a meteorite that was found in the south pole. It is thought to have originally come from Mars. Around 4 billion years ago, the rock was thought to have been ejected from the Martian surface by a large impact. The rock was then thought to have remained in space, until it came into contact with Earth around 13,000 years ago. It is special as it is the only known martian rock to have been ejected from the martian surface during a time when there was thought to be liquid water on the planets surface, essential for life. On examination of the rock, scientists saw `worm like` micro fossils, thinking that they were the remains of early martian life. These features have now been generally dismissed as early martian life forms, but the meteorite remains a very important find.
