Wegener was intrigued when the same Mesosaurus fossils, an ancient freshwater reptile, showed up on different continents.
What hypothesis did he propose to explain this?
A: The continents were at one time joined together.
B: The Mesosaurus swam between the two continents.
C: The fossils were moved by humans.
D: The fossils must be of different species.
Wegner simply defined it by saying that the continents were all together at one point in time. He defined this by explaining his Continental Drift theory. Hence option A is appropriate.
Alfred Lothar Wegner as is known as one of the foremost and most important people of his time. He was a Geologist as well as a climatologist.
Wegner during his time as a Geologist had given a path-breaking discovery that later the world cherished and became a ground for a lot of future generations. After, looking at the work of the solid spheres over time, and also by finding the Mesosauraus Fossil he could only come to the idea of Continental Drift Theory.
The Continental Drift Theory is such that, Wegner believed that during the Ancient Greek Civilizations, Earth was one big continent., Later on, the Pangea of the whole continent broke, and thus fragments of the continents started to float around and got separated. Hence, option A is correct.

Answer:
A: the continents were at one time, joined together (and then somehow drifted apart)
Explanation:
metamorphic rock are the rock which are formed when igneous rock and sedimentary rock change from one form to another form due to more heat and pressure. long time exposure of heat and pressure on the sedimentary rock and igneous rock changes them from one form to another form and metamorphic rocks get form
The current theory for star formation is that stars form within dwarf ionizedclouds.
The question is fill in the blanks and the answers are written below.
Stars form where there are dense cores within clumps of gas and dust in these clouds.
The formation of a protostar involves the rapid collapse of infalling gas...
As a protostar shrinks, its rate of spin decreases.
This allows subsequent infalling gas to accumulate at the equator... accumulate at the protostar's poles due to its spinning motion.
When it has nearly reached its final mass, it is called a Wolf-Rayet star.

Answer:
The current theory for star formation is that stars form within giant molecular clouds. Stars form where there are dense cores within clumps of gas and dust in these clouds. The formation of a protostar involves the rapid collapse of infalling gas onto a dense core due to gravity. As a protostar shrinks, its rate of spin decreases. This allows subsequent infalling gas to accumulate at the equator of the protostar; this material tends not to accummulate at the protostar's poles due to its spinning motion. As the protostar continues to evolve, it emits infrared radiation. When it has nearly reached its final mass, it is called a Wolf-Rayet star. These objects produce strong stellar winds.

Answer:
35°
Explanation:
j and 35° are vertically opposite angles so their measures are equal and 35° each.
Answer:
It is very difficult to separate these things from each other because they always go hand in hand, not one by one.
Explanation:
When it comes to ethnic disputes, socio-economic competition, struggles for political dominance, and religious animosity, it is impossible to separate them. The reason for that is that they are intermingled and function together. At least two of these are functioning together, though very often it is all four simultaneously.
The ethnic disputes very often tend to occur because of socio-economic compeition between the different groups, mostly when the situation is not good. The religion, especially if the groups have different religions, always comes up on the front to support the ethnic group that follows it, and the political leaders use the opportunity to fuel things up in order to get full control of a particular region, or even outside of the ethnic boundaries.
