Hint: We can use the information that the tides' generation takes place due to the moon's gravitational force. The moon tends to attract the water that is present on the surface of the earth. Due to attraction, the water rises from the earth's surface and causes tides on the planet. So, the earth's poison with respect to the moon and its effects on the earth due to the moon gives us some idea about how many times a day tide occurs on the earth's surface.
Complete step by step answer:
Tides are the variations of the earth's water level on its coastlines. As the generation of tides occurs, the sea's water level near the beach rises, and when the tides go out, the sea's water level goes down. Generally, tides occur in all water surfaces, but they are most noticeable in the sea and large lakes.
When the earth is closest to the moon, and the earth faces full moon and new moon condition, the gravitational effect of the moon is very high on the earth, so in these conditions, earth's water experiences an attractive force at the point where the earth is closest to the moon, but at the earth's farthest point from the moon, water experiences outward force. Due to these two forces, the generation of two high tides takes place on the earth.Therefore, two times a day, the high tides occur on the earth, and option (B) is correct.
Note:The two types of tides occur in the water: low tides and high tides; the low tides occur when the moon's gravitational pull on the earth is less. The moon's gravitational pull is less because earth is inclined at some angle with the moon, but if the earth faces the full moon, then the moon's gravitational force on earth increases up to a large amount. So, due to the large gravitational force, the generation of high tides occurs on the earth.
