Answer:
C: Plates float on the liquid mantle located below the crust.
Explanation:
Plates at our planet’s surface move because of the intense heat in the Earth’s core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again.
Scientists once thought that Earth’s plates just surfed on top of the mantle’s giant convection cells, but now scientists believe that plates help themselves move instead of just surfing along. Just like convection cells, plates have warmer, thinner parts that are more likely to rise, and colder, denser parts that are more likely to sink.

Answer:
Ganymede is the biggest and the most massive moon of the planet Jupiter. It has a metallic core. It moves in an orbital path around the planet Jupiter and orbits every 6-7 days. Half of the moon is comprised of silicate rocky materials and half of it is made up of water ice. Out of all the moons, Ganymede has the highest rock composition.
Europa is one of the moons of Jupiter. It is even smaller than the earth's natural satellite (moon). The core of this moon is made up of iron and nickel, along with some silicate materials but they are extremely in a lesser amount in comparison to the earth's core. Europa's surface is comprised of ice and water is present in a significant amount below the surface.
