Answer:
Lunar phases are given below.
Explanation:
- The Moon Is a natural satellite of earth and has the same rotational motion of earth thus we tend to see the same face every day and each year as the moon has 7-8 phases and each phase is a product of the interaction of the moon with the sun's solar light.
- The first phase is of a new moon i.e the disk is completely invisible to the earth, starts at noon from 6 am to 6 pm. Then comes the waxing crescent period of the moon in which the moon is a 90-degree angle is 0.1% of the sick is visible as a crescent form starting from 9 am to 9 pm.
- The first quarter comes up at midnight and when the moon disk is at 50% visible to the earth and this starts at 6 pm at noon. The waxing gibbous moon occurs at the 3 am to 3 pm and the disk is 50 to 99% lit by the sun.
- Followed by the full moon and which has 100% of the disk visible to earth and usually starts from 6 pm to 6 am. And ret follows when the moon declines its axis from the slope of earth.
Answer:
Option (C)
Explanation:
The continental drift theory was introduced by Alfred Wegener. He said that the continents moved over the vast ocean surface from one place to another.
He contributed many pieces of evidences in support f this theory, which includes the founding of similar fossil assemblages, similar rocks types in the distant continents, matching of the continental boundaries, but he was not able to explain the main mechanism behind the continental motion.
Due to this, this theory was not accepted by the other scientists and he was criticized by them.
Later, this theory was modified into the Plate tectonic theory which was successful in explaining the mechanism behind the continental motion i.e the formation of convection current in mantle that drives the plates movement.
Thus, the correct answer is option (C).
