In the early twentieth century, Alfred Wegener proposed the continental drift hypothesis. He thought the continents had once been joined together and had drifted apart. Look at the images of Africa and South America. They look like they fit together like a puzzle piece. What other patterns do you notice in the shape of the continents to suggest that they once all fit together

The correct answer is - The Sun, because it's the largest body in the solar system.

The Sun is the center of the our solar system. It is the only star in it, and it is the only objects that radiates light and heat from it, while all the other objects are cold objects that are dependent on it for their temperatures.

Also, the Sun is by far the biggest object in the solar system, thus it has the biggest mass, and that gives it its very big gravitational pull, which is much bigger than the second biggest of the planet Jupiter.

The correct answer are: C. heat, and E. pressure.

All metamorphic rocks need this two factors so that they can be formed from either igneous or sedimentary rocks. The metamorphic rocks form deep into the ground where the pressure is higher and the temperature is higher as well, the deeper they form the bigger the pressure and temperature they experience. According to how big of a temperature and how big of a pressure the rocks have been exposed it determines into what type of metamorphic rocks they will turn into, and according to that what kind of a texture and appearance will they have. The amount of time of exposure to heat and pressure is also key to the type and quality of the metamorphic rocks.
