The correct answer is (2)
The moon's rotational period was wasn't always equal to its orbit (revolution) around the planet. Just like gravity of the moon affects ocean tides on the earth, gravity from earth affects the moon. But because the moon lacks an ocean, earth pulls on its crust, creating a tidal bulge at the line that points toward earth.
Gravity from earth pulls on the closest tidal bulge, trying to keep it aligned. This creates tidal friction that slows the moon's rotation. Over time, the rotation was slowed enough that the moon's orbit and orbit and rotation matched, and the same face became tidally locked forever pointed toward earth.
Answer:
Mantle convection currents, ridge push and slab pull are three of the forces that have been proposed as the main drivers of plate movement (based on What drives the plates? Pete Loader). There are a number of competing theories that attempt to explain what drives the movement of tectonic plates.
Explanation:
Answer:
45° West longitude - somewhere in South America (may be Brazil).
To calculate the time difference between the school and the family in Bhutan, we need to take into account the first time zone located in Greenwich, London, United Kingdom.
Between the time zone corresponding to the first meridian and the location of the school = 3 hours
Between the first meridian and the location of the family in Bhutan = 6 hours
So, the difference in hours between the school where I study and the family in Bhutan = 9 hours.
