During a quarter moon, the Sun, Earth, and Moon are positioned at a right angle to each other. This alignment occurs when the Moon is either in its first quarter or last quarter phase, with the Earth located between the Sun and the Moon in the case of the first quarter, and the Moon positioned between the Earth and the Sun during the last quarter. As a result, half of the Moon's surface facing Earth is illuminated, creating the distinct half-moon appearance.
They are at 'right-angles', with the Earth at the corner of the right angle.
During neap tides, the moon is positioned at a 90-degree angle relative to the sun, with the Earth in between. This alignment results in the gravitational forces of the sun and moon partially canceling each other out, leading to lower tidal ranges compared to during spring tides.
During a first quarter moon, the Earth is positioned between the Sun and the Moon. The Moon is at a 90-degree angle relative to the Earth and the Sun, meaning that half of the Moon's surface is illuminated by sunlight, which appears as a half-moon from Earth. This phase occurs roughly a week after the new moon and is part of the lunar cycle.
During the first and third quarter phases of the moon, known as the neap tides, the gravitational pull of the sun and moon work against each other, producing the least variation in tides on Earth. This results in lower high tides and higher low tides during these phases.
During a quarter phase of the Moon, either the first or third quarter, the Earth, Moon, and Sun are positioned at approximately right angles to each other. In the first quarter phase, the Moon is located between the Earth and the Sun, while in the third quarter phase, the Earth is between the Moon and the Sun. This positioning causes half of the Moon's surface to be illuminated and visible from Earth, creating the characteristic half-moon appearance.

First Quarter occurs when the moon is at right angles with respect to the Earth and sun. During this phase, the moon has completed one quarter of it's orbit around the Earth and an observer on Earth will see half of the moon illuminated.
They are at 'right-angles', with the Earth at the corner of the right angle.
The amount of the lighted side of the moon you can see is the same during the first quarter and the last quarter phases. In both phases, half of the moon's illuminated side is visible from Earth.
A quarter moon, also known as a first or last quarter moon, appears as a half-circle or semicircle when viewed from Earth. During the first quarter, the right half is illuminated, while in the last quarter, the left half is lit. This shape results from the relative positions of the Earth, Moon, and Sun.
The phase of the Earth's satellite, the Moon, changes as it orbits the Earth. The primary phases are new moon, first quarter, full moon, and last quarter. These phases are determined by the position of the Moon relative to the Earth and the Sun.
During neap tides, the moon is positioned at a 90-degree angle relative to the sun, with the Earth in between. This alignment results in the gravitational forces of the sun and moon partially canceling each other out, leading to lower tidal ranges compared to during spring tides.
When the moon has completed half of its revolution around the Earth, it is referred to as the "First Quarter" or "Last Quarter," depending on its position in relation to the Earth and the Sun. In the First Quarter phase, the right half of the moon is illuminated, while in the Last Quarter, the left half is lit up. These phases occur approximately one week apart in the lunar cycle.
New moon, first quarter, full moon and third quarter
A first quarter moon is 90 degrees from the earth and the sun. Therefore, it rises around noon. Last quarter moons are also at 90 degrees, but the 'other' 90 degrees, 180 degrees from the first quarter position. So last quarter moons rise around midnight. The moon always rises in the east.
