The lunar rover was a vehicle that was used for Apollo 15, 16. and 17. They were used to transport the astronauts across the lunar surface. They remain on the moon today.
(Answered as "What travels across the surface of the Earth when an eclipse occurs?") The shadow of the Moon travels across the Earth during a Solar Eclipse. (During a Lunar Eclipse, the shadow of the Earth travels across the Moon.)
they move across the sun's surface :)
Mars Valles Marineris is the largest canyon found in our Solar System. Located in the Southwestern Hemisphere of Mars, the canyon stretches 2,500 mi (4,000 km) across the Martian surface and covers approximately one fifth of the planet's circumference. This canyon is also 400 mi (650 km) wide at places and have depths of over 3.8 mi (6.1 km) deep.
The moon measures 2,160 miles across. It was figured out by the first astronauts to set out on the moon on the Apollo 11, Buzz Aldrin and Neil Armstrong.
LEM - Lunar Excursion Module - A small 'car' that was used to move across the surface to collect samples.

The Apollo 15 were the first to use the moon rover on the moon astronaut David scott and James Irwin were the two to travel.
Energy
Of course they can. Astronauts have been doing it for years.
The road expansion across the Martian landscape will require between thirty and fifty engineers, due to the massive size and scope of the project and the difficulty of navigating through the Martian landscape.
Push a box across a surface with a downward angle because gravity is helping.
"surface tension"
One of the reasons worms are long are because of their general biological makeup. They have a very simple design lacking in lungs. They acquire their needed oxygen by diffusion through their skin. In order for a worm to acquire more oxygen a greater surface area is needed. This increased surface area can be accomplished by the worm being long and thin, but not by the worm being short and fat. it's an equation of surface area to volume. In being long and thin the oxygen can easily and rapidly diffuse across the worms membranes.
Water flowing downhill across the surface of the Earth is called runoff.
Large bodies of ice that move across the Earth's surface are glaciers.
Advection fog results when moist air moved across a cold surface. When moving across a cold surface, the air is cooled to its dew point.
