Explanation:

An inch of rainfall refers to the amount of water that would cover the ground to a depth of 1 inch, provided none of it evaporates, percolates, or drains off. It is a measure of the volume of water that falls on a particular area during a rainfall event.

Details:

- Definition: An inch of rainfall is the depth of water that would accumulate on the ground if all the precipitation fell and remained in place without any loss due to evaporation, percolation, or runoff.
- Measurement: Rainfall is measured in inches or millimeters, indicating how much water falls on a specific area.
- Hydrological Cycle: Rainfall is a crucial part of the hydrological cycle, where water evaporates from oceans, lakes, and other water bodies, forms clouds, and falls back to the earth's surface as precipitation.
- Rain Gauge: Rainfall is measured using a rain gauge, which is a cylindrical container placed in an open area to collect and measure the amount of precipitation.
- Volume of Water: An inch of rainfall does not provide information about the total volume of water. It only indicates the depth or height of the water that would cover the ground.
- Evaporation, Percolation, and Runoff: In reality, rainfall does not remain in place. Some of the water evaporates back into the atmosphere, some percolates into the soil, and some flows off the ground as runoff into rivers, streams, or other water bodies.
- Importance: Understanding the amount of rainfall is crucial for various applications such as agriculture, water resource management, flood prediction, and climate studies.
- Rainfall Variability: Rainfall patterns can vary significantly across different regions and seasons. It can be influenced by factors such as geographical location, climate, topography, and atmospheric conditions.
- Conversion: Inches of rainfall can be converted to other units such as millimeters by using conversion factors. For example, one inch is approximately equal to 25.4 millimeters.

In conclusion, an inch of rainfall refers to the depth of water that would cover the ground if none of it evaporates, percolates, or drains off. It is a measure of the amount of water that falls during a rainfall event and is important for various applications related to water resources and climate.

Milankovitch proposed in the early twentieth century that the ice ages were caused by variations in the Earth’s orbit around the Sun. For some time, this theory was considered untestable, largely because there was no sufficiently precise chronology of the ice ages with which the orbital variations could be matched. To establish such a chronology, it is necessary to determine the relative amounts of land ice that existed at various times in the Earth’s past. A recent discovery makes such a determination possible: relative land-ice volume for a given period can be deduced from the ratio of two oxygen isotopes, 16 and 18, found in ocean sediments. Almost all the oxygen in water is oxygen 16, but a few molecules out of every thousand incorporate the heavier isotope 18.When an ice age begins, the continental ice sheets grow, steadily reducing the amount of water evaporated from the ocean that will eventually return to it. Because heavier isotopes tend to be left behind when water evaporates from the ocean surfaces, the remaining ocean water becomes progressively enriched in oxygen 18. The degree of enrichment can be determined by analyzing ocean sediments of the period, because these sediments are composed of calcium carbonate shells of marine organisms, shells that were constructed with oxygen atoms drawn from the surrounding ocean. The higher the ratio of oxygen 18 to oxygen 16 in a sedimentary specimen, the more land ice there was when the sediment was laid down.It can be inferred from the passage that precipitation formed from evaporated ocean water has
