Alfred Wegner proposed the theory of Continental drift which suggested the continents move and started out in different positions from what they are currently. In the 1960s, scientists discovered the spreading apart of the seafloor. This in turn led to the theory of Plate tectonics. This theory says that the earth's outer crust, the lithosphere is made of plates which float on a "plasticlike" undersurface called the asthenosphere. Where these plates come together at their boundaries, changes take place in the crust and its feature.

Explanation:

Alfred Wegner proposed the theory of Continental drift which suggested the continents all continents were once connected in a large single mass that broke apart around 200 million years ago before slowly moving apart to where they are currently.

In the 1960s, Harry Hess, a geologist and Navy submarine commander during World War II, discovered the spreading apart of the seafloor. This in turn led to the theory of Plate tectonics. This theory says that the earth's outer crust, the lithosphere is made of plates which float on a "plasticlike" undersurface called the asthenosphere. Where these plates come together at their boundaries, changes take place in the crust and its feature.

the sunflower because each experiment got the same results

hope this !

the farther away the object is from the central star (the sun) it's gravitainal pull on the object is weaker when it is farther
