A catalyst undergoes no chemical change during a chemical reaction.
Approximately 67.8% of earth's surface is covered by salt water while only 3% is covered by fresh water. In total, the earth's surface is covered by 70.8% of water.
Earth's accessible surface freshwater is primarily located in lakes, rivers, and reservoirs, with approximately 87% found in lakes. Groundwater accounts for a significant portion as well, but only about 0.3% of the Earth's total freshwater is surface freshwater. Overall, surface freshwater constitutes about 0.3% of the total freshwater resources available on Earth. This limited availability highlights the importance of conserving and managing these vital water sources.
Approximately 68.7% of Earth's freshwater is stored in polar ice caps, glaciers, and permanent snow. This accounts for about 1.7% of the total water on the planet, as the majority of Earth's water (about 97.5%) is saltwater found in oceans. The remaining freshwater is primarily found in lakes, rivers, and underground aquifers.

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.
No, the polar regions do not receive the most insolation; they actually receive the least. Insolation, or incoming solar radiation, is highest at the equator due to the direct angle of sunlight. In contrast, the polar regions receive sunlight at a much oblique angle, spreading the energy over a larger area and resulting in less effective heating. Additionally, during winter months, polar regions can experience prolonged periods of darkness, further reducing their total insolation.
the change can be brought about by mostly the industrial sector due to the injudicious use of mineral resources. the fumes or gaseous matter diffuse into the upper atmosphere to degrade its stability. the ozone layer has oxygen in molecular O3 form. due to weakening of this layer by the above mentioned agents, the UV rays of the sun break it down to molecular O2 & [O], which is pure atomic nascent oxygen. this depletes the ozone layer's efficiency & makes it permeable to these rays............

The total amount of Earths total water supply that is usable fresh water is less then two percent. The rest is salt water or pond water.
That is a total eclipse of the sun.
