Answer: The answer is A. Jovian moons are made mostly of ice that can melt and deform at lower temperatures than the rock and metal that make up the Moon and Mercury

Explanation: Jovian moons are moons of Jupiter. There are about 79 known moons in Jupiter. They are mostly made up of ice.

The main component of geological activity (change in surface features and landscapes of a planet) is heat. The ice that makes up Jovian moon can easily melt or deform compared to rock and metal that made up both Moon and Mercury. This as a result explains why there is more geological activities in Jovian moons compared to Moon and Mercury.

Which of the following was NOT an observation that supported the original continental drift hypothesis as posed by its originato
Over [174]

Answer:

Option (C)

Explanation:

The continental drift hypothesis refers to the large scale, slow motion of continents over the surface of the large ocean basins and it was discovered by Mr. Alfred Wegener. He contributed some evidence regarding this continental drift hypothesis, such as the matching of the continental margins, finding similar fossils in distant continents, finding similar rock types as well as structures present in them. The movement of glaciers and their changing patterns were also observed to prove this theory.

But, of all the given options, one observation does not support the hypothesis, i.e. the lithosphere showing ductile nature in comparison to the brittle rock behavior in the layer of the asthenosphere.

In the brittle zone, the rocks fractures due to the force acting on it, whereas, in the ductile zone, the rocks tend to flow during the time of deformation.

Thus, the correct answer is option (C).

The frigid temperatures have allowed a lake to become ready for people to ice fish on it. What process has the lake undergone? ​
Burka [1]

Answer:

When the entire lake reaches 40 F, the surface water cools further, dropping below 40 F. Because this water is now less dense than the surrounding water, it will stay on the top and continue to cool. Once the surface water falls to 32 F, it freezes. The freezing then spreads downward into the lake and the ice thickens
