A change in Earth's total insulation can be caused by variations in the Sun's output, changes in Earth's orbit, or alterations in the composition of Earth's atmosphere such as increased greenhouse gas concentrations.
The weight of the Earth remains constant because the total mass of the Earth does not change. However, variations in the distribution of mass on Earth's surface, such as through movements of ice or tectonic activity, can cause localized changes in weight.
During a total lunar eclipse, when the Moon is in Earth's umbral shadow, one will witness the Moon appearing red or orange in color. This phenomenon is often referred to as a "blood moon" due to the reddish hue caused by the scattering of sunlight through Earth's atmosphere.
A solar eclipse occurs when the Moon passes between the Earth and the Sun, blocking the Sun's light from reaching the Earth. This alignment causes the Moon to cast a shadow on the Earth, resulting in either a partial or total solar eclipse.
The total amount of water on Earth remains relatively constant over time due to the water cycle, which involves processes like evaporation, condensation, and precipitation. While water may change form or location (e.g., from liquid to vapor), the overall quantity of water on Earth remains stable.

Changes in Earth's total insolation can be caused by variations in the distance between Earth and the Sun due to the Earth's elliptical orbit (Milankovitch cycles), changes in the Earth's axial tilt, and variations in the transparency of the atmosphere due to factors like greenhouse gas concentrations and volcanic activity.

A change in Earth's total insulation can be caused by variations in the Sun's output, changes in Earth's orbit, or alterations in the composition of Earth's atmosphere such as increased greenhouse gas concentrations.
Changes in the Earth's orbit, variations in solar output, changes in atmospheric composition (such as greenhouse gas concentrations), and presence of natural phenomena like volcanic eruptions can all affect the Earth's total insolation.
Insolation, or the amount of solar radiation received, decreases as latitude increases. This is because at higher latitudes, the angle at which sunlight reaches the Earth's surface becomes more oblique, leading to greater scattering and absorption of sunlight in the atmosphere. Additionally, the length of daylight hours also varies with latitude, impacting the total insolation received at different latitudes.
The total amount of water on Earth remains relatively constant over time, so the total volume of water in the hydrosphere does not change.
The total amount of water on Earth remains relatively constant because water undergoes the hydrological cycle, where it is continually recycled through processes like evaporation, condensation, and precipitation. While water may change states or locations, the total amount of water on Earth overall remains the same.
fairly constant
The total volume of Earth's crust is estimated to be around 1% of the Earth's total volume. This corresponds to roughly 0.47% of Earth's total mass.
