Yes! When looking at the surface of Mars there is evidence of landforms we recognise on earth like volcanos, one of the volcanos on Mars is called Olympus Mons. It is known that martian volcanoes have erupted within the past approximate 180 million years, which is considered quite recent.

Yes, there is also evidence of erosion and the most amazing and huge landslides on Mars. Some of them caused by the action of erosion and gravity (there is a gravity force on Mars even if it smaller than the one on Earth) and some of them caused by meteorite impact. Landslide on Mars are also studied to understand large ones on Earth, to compare environment with or without the presence of water.

For me, as a geologist interested in sedimentary rocks, Mars is fascinating, as there is now geological evidence of all sorts of environments that we find on Earth: rivers, wind-blown sand dunes, lakes, and seas. The Mars Curiosity rover has been exploring Gale Crater and finding all manner of amazing geological features, including a 3.5 billion year-old salty lake, which you can read all about on the NASA website here: https://mars.nasa.gov/news/8522/nasas-curiosity-rover-finds-an-ancient-oasis-on-mars/?site=msl
