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.
Answers
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.
What is a Continental Drift Theory?
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.

Since the air balloon is just south of the Equator and it moves towards west, that means the trade winds are moving it in that direction. The trade winds are winds that are active around the Equator and there direction of movement is east-west, thus they are wind that blows to the west.

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.

One hundred Japanese yen is able to buy 7.93 Mexican pesos.
The exchange rate between the Chinese yuan and the U.S. dollar is 1.0853.
One U.S. dollar is able to buy 1.0853 Canadian dollars.
Answers
The answer is best gotten using dimensional analysis depending on the choices.
(a) 100 Japanese Yen (12.8575 Mexican Peso/101.96 Japan Yen) = 12.61 Mexican Peso (FALSE)
(b) 1 Chinese Yuan ( 1 U.S. dollar / 6.2471 Chinese Yuan) = 0.16 U.S dollar (FALSE)
(c) 1 U.S dollar (1.0853 Canadian dollar/ 1 U.S. dollar ) = 1.0853 Canadian dollar (TRUE)
The answer therefore is C. As this is the only option that is valid with the the premises.

Answers
Answer:
1- SLEET
2- HAIL
3- RAIN
4- FREEZING RAIN
5- SNOW
Explanation:
(1) Sleet- Sleet refers to the type of rain that forms very small ice crystals as it falls from the cold air. This cold air provides a much cooler temperature favoring in the formation of these crystals.
(2) Hail- When the ice pellets are allowed to scatter within the dense cloud, then the ice pellets combine with the water droplets present at a higher altitude. It then grows larger in size, and after this continuous motion of ice pellets, they fall back on the surface.
(3) Rain- It is the most commonly occurring precipitation and these raindrops are formed when the ice crystals in the clouds are melt.
(4) Freezing Rain- These are raindrops that usually gets freeze as they fall over the surface in a comparatively colder weather. After precipitation, the surface gets covered by these ice coatings.
(5) Snow- The ice crystals when it grows and gets accumulated in the clouds, they form snowflakes that are of variable shapes and sizes.
Hence the correct answers are being matched.

As we know that sum of three angles of triangle is 180º.
we have
The angles a and c are equal so,
