Answer:
B. it is based on the idea that all the present continents were one supercontinent
Explanation:
This is the answer because Pangaea is the name of the supercontinent whose existence is theorized. This theory supports plate tectonics because if it wasn't for plate tectonics, all the continents would still be a single large landmass.
I'd have to say gas because it usually doesn't change at all
Answer:
Option (C)
Explanation:
San Andreas is a prominent example of a transform fault, in which the plates namely the Pacific Plate and the North American plate slide past each other. The movement of the associated plates in this fault is in the right lateral, strike-slip. With the continuous and rapid movement of both the plates in its respective direction, the west side of the fault would get detached from the fault zone and lead to the formation of an island. The movement of the plates along this fault is responsible for the occurrence of shallow focus tremendous earthquakes.
Thus, the correct answer is option (C).
The development of the population policies in the 20th century were due too multiple factors, the most important of which were:
- Fertility rates were starting to lower down, especially in the ''western world'' in the second half of the 20th century.
- Increased demand for labor force.
- The World Wars, especially the second one caused huge migration movements.
- Millions of people from less developed countries were trying to migrate to more developed countries in search of a better life.
Hmm, first of all, the angular size of the moon is around
. When we measure sizes of objects in the sky, we cannot determine how far each of them lies and we cannot acoount for that; so for example, the sun and the moon have roughly the same size on the sky, despite the sun being much bigger in reality. This "sky-size" is measure with how big an angle the spherical object takes up in the sky (and specifically how big an angle a diameter of that object takes up). A whole circle around the night sky takes up 360 degrees, so 720 moons could fit in this circle (approximately). We see that a degree is a big unit of measurement, so we have smaller ones. Degrees have a subdivision, arcminutes. One arcminute is 1/60 of a degree. Thus 1 degree has 60 arcminutes in it. Hence, half a degree contains 30 arcminutes. Thus, the moon has roughly an angular size of 30 arcminutes.
