Europa, one of Jupiter's moons, is a natural satellite where it is believed that ice flows. This is due to its icy surface, which shows evidence of crustal plates moving and shifting over time, suggesting the presence of subsurface oceans kept warm by tidal forces.

The moon is not a planet. You've all probably heard about the International Astronomical Union (IAU) decision to define a planet -- probably because it clarified that there is a big belt of icy objects out beyond the orbit of Neptune, and we now know that Pluto is one of thousands of them. The IAU definition also excludes moons from being planets. But did you know our moon functions like a planet? It has a lot to teach us about how planets form and evolve. Another hallmark of planets is that they have active geology. The big, dark splotches you see on the moon's surface are lava flows. Yes, there were active volcanoes on the moon. There aren't any volcanic cones, because the lava was very fluid and flowed out through cracks and into low-lying areas. The Apollo samples contain small beads of volcanic glass that tell us there were giant fire-fountains on the moon too. Though volcanic activity on the moon ended about 3 billion years ago, the Apollo missions picked up thousands of earthquakes on the moon, or moonquakes. Moonquakes tell us that the moon is not geologically dead. It's still acting like a planet today. Let me sum this up for the people who don't know most of these words in here. The moon isn't a planet. But acts like a planet today. Earth's moon (Luna) is not a planet, it is a moon. It does not have an independent orbit (it orbits a planet, not a star).

The Amur River, known as the tenth longest river on the planet, flows between Inner Manchuria and Russian Far East.
Grand Canyon.
No natural river flows in a straight line.
A lightning rod is grounded, meaning it connects to the ground, and the ground is the last place the charge flows to. It is absorbed into the planet Earth.
You probably mean the river bed.
Idaho has several, but the Snake is probably the best known.
