The concepts used to solve this exercise are given through the calculation of distances (from the Moon to the earth and vice versa) as well as the gravitational potential energy.
By definition the gravitational potential energy is given by,

Where,
m = Mass of Moon
G = Gravitational Universal Constant
M = Mass of Ocean
r = Radius
First we calculate the mass through the ratio given by density.



PART A) Gravitational potential energy of the Moon–Pacific Ocean system when the Pacific is facing away from the Moon
Now we define the radius at the most distant point

Then the potential energy at this point would be,



PART B) when Earth has rotated so that the Pacific Ocean faces toward the Moon.
At the nearest point we perform the same as the previous process, we calculate the radius

The we calculate the Potential gravitational energy,



Sometimes it just picks for you
To find average speed, we divide the distance of travel (in this case, 400 metres) by the time she took, 32 seconds. Therefore: 12.5 seconds is her average speed.
Answer:
Plate tectonics are responsible for the following events by:-
Explanation:
Plate tectonics are parts of the crust which is moved by the mantle of the Earth.
The Crust is divided into parts called "Tectonic Plates"!
When tectonic plates move they cause some sorts of anomalies, and some of those anomalies are the ones in the question.
When there are two tectonic plates move towards each other, they form mountains, or when wo tectonic plates move away from each other, they cause the sea floor to expand!
Sometimes, they can cause dangerous accidents because of the vibration of the tectonic plates. These vibrations can cause volcanic eruption and tsunamis and Earth quakes.
When these volcanic eruptions occur, they can form underwater volcanoes, and make new islands, which can lead to continent formation!
I hope this answer helps, and I also hope this answer is what you are looking for!
Answer:
Geology is the study of the Earth that involves the process at Earth, materials of which it is made, and its history.
<u>Geologists combine both laboratory and field data to illustrate the results of their research. Some observations that can the geologist make by working outdoors instead of in a lab are as follows:</u>
- Understanding and exploring the earth's surface closely using geophysical tools.
- Collecting samples by own and make some interpretations at the same time.
- Observation of the landscapes
- Close observation of outcrops
