Answer:
<u>Earth's rotation and gravitational attraction of the sun and the moon to some extent are responsible for the motion of tides in the oceans. As the oceans are so vast there exist a cyclic flow water.</u>
Explanation:
- As the earth has its gravity and so does the other phenomenon like stars and moon have there thought this is not felt directly as the tidal bulges that are seen around the earth occur at two times in a day and two times at evening time due to the course of earth rotation having a cyclic time of 12 hours.
- The gravitational pull of the moon is not that strong but since it is close to the earth's surface the tidal bulges are felt on a full moon day and a new moon day as the oceanic currents rise by the gravitational attraction of the moon at night.
- In the day this is noticeable, as the sun has a large attractive force on the planet derives the winds and pressure belts around the globe, When these celestial objects all fall in the same line both ends on earth experience two small and large tidal bulges on east and west sides.
I don’t know I’m just answering this so I can ask more questions.
The answer is hill hope it's helps
Which one should I do?? All of them??
Answer:
An index fossil should be found in many parts of the world.
Explanation:
A is not correct because if fossils are found in one area than they will not be able to give a general picture of the world in a particular period.
B is not correct because if fossils are found in only two locations they will be able to give information for only those two places, not the rest of the world.
C is not correct because this is simply not possible, not just for the number of fossils required, but also because the majority of the rock types don't provide conditions for fossilization.
D is correct because by being found in numerous places across the world, the index fossils can give a general picture of the biodiversity, but also the climate, and living conditions in a particular time frame.
