When the gravity of the sun and moon pull on Earth's surface at right angles, a neap tide occurs. This phenomenon happens during the first and third quarters of the moon when the gravitational forces of the sun and moon partially cancel each other out. As a result, the difference between high and low tides is less pronounced than during spring tides, which occur when the sun and moon are aligned.
When the gravity of the sun and moon pull Earth's surface in opposite directions, it results in a neap tide. During neap tides, the difference between high and low tides is minimized, occurring during the first and third quarters of the moon. This happens because the gravitational forces partially cancel each other out, leading to lower tidal ranges.
The gravity in the Space Shuttle is essentially the same as gravity on Earth's surface, which is about 9.81 m/s². However, while in orbit, the Space Shuttle and its occupants experience microgravity, creating a sensation of weightlessness. This occurs because the shuttle is in free fall, continuously falling towards Earth but also moving forward at a high speed, resulting in a state of perpetual free fall around the planet. Thus, while gravitational pull remains the same, the effects felt inside the shuttle differ due to its orbital motion.
Neap tides are caused when the gravitational pull of the sun and moon are at right angles from each other, resulting in the least difference between high and low tide levels. This occurs during the first and third quarters of the moon.
When the gravity of the sun and moon pull Earth's surface in the same direction, it results in a spring tide. This phenomenon occurs during the full moon and new moon phases when the sun, moon, and Earth align. Spring tides produce higher high tides and lower low tides due to the combined gravitational forces.

When objects free fall near Earth's surface, they experience constant acceleration due to gravity. This means that the objects increase their velocity by the same amount each second while falling. The acceleration due to gravity near Earth's surface is approximately 9.8 m/s^2.
The troposphere is the layer of the atmosphere where weather occurs and is closest to Earth's surface. It extends from the surface up to an average altitude of 10-15 kilometers, although its thickness can vary depending on latitude and season.
The slipping or sliding surface of parts of the Earth's surface is known as a fault line. This is where movement occurs along the surface of the Earth, resulting in earthquakes.
