The lunar phase that occurs when the Moon is directly between the Sun and the Earth, causing the Moon to appear completely dark from our perspective on Earth, is called the New Moon.

What force causes Tides?
Tides are primarily caused by the gravitational forces exerted by the Moon and the Sun on the Earth's oceans. The Moon's gravitational pull creates a "bulge" of water on the side of the Earth that faces the Moon, resulting in a high tide. Conversely, there is another high tide on the opposite side of the Earth due to the centrifugal force arising from the Earth-Moon system's rotation. The Sun also exerts a gravitational force that affects tides, though its impact is less than that of the Moon. The combined effects of the Moon's and Sun's gravitational pulls create the tidal cycles we observe on Earth.
What type of tide produces the highest high tides and the lowest low tides when the Sun, Moon, and Earth are aligned in a straight line ?
The type of tide that produces the highest high tides and the lowest low tides when the Sun, Moon, and Earth are aligned in a straight line is called spring tides. This alignment occurs during the full moon and new moon phases, when the gravitational forces of the Moon and the Sun combine to create more pronounced tidal effects.
What causes the day and night cycle on Earth?
The day and night cycle on Earth is caused by the Earth's rotation on its axis. As the Earth rotates, different parts of its surface move into and out of the sunlight.
- When a particular side of the Earth faces the Sun, it experiences daylight, while the side facing away from the Sun experiences night.
- This rotation takes approximately 24 hours to complete one full cycle, which is why we have a 24-hour day. The rotation of the Earth is counterclockwise when viewed from above the North Pole, leading to the Sun appearing to rise in the east and set in the west.
In summary, the continuous rotation of the Earth is the primary reason for the cyclical pattern of day and night.
What is the main reason we experience different seasons on Earth?
The main reason we experience different seasons on Earth is the tilt of the Earth's axis relative to its orbit around the Sun. The Earth's axis is tilted at an angle of approximately 23.5 degrees.
As the Earth orbits the Sun throughout the year, this axial tilt causes different parts of the Earth to receive varying amounts of sunlight at different times of the year.
- During the summer solstice, the Northern Hemisphere is tilted toward the Sun, receiving more direct sunlight and experiencing warmer temperatures.
- Conversely, during the winter solstice, the Northern Hemisphere is tilted away from the Sun, receiving less direct sunlight, resulting in cooler temperatures.
The Southern Hemisphere experiences the opposite effect: when it's summer in the Northern Hemisphere, it's winter in the Southern Hemisphere, and vice versa. This axial tilt and the resulting variation in sunlight exposure are what produce the changing seasons throughout the year.
