Answer:
Regions with a higher amount of rainfall are those of equatorial regions and those of the low rainfall are polar areas.
Explanation:
- The regions in the tropics and the subtropics receive a significant amount of rainfall while the place at the places receives only 10 inches f rainfall and regions are dry annually with rain occurring only in summer.
- The tropical areas are those that surround the earth equator and are found 23 degrees north and south. As the sun is usually in direct contact and this region comprise of 40% of the surface area and 35% of the earth's landmass. And remains warm to hot and moist year-round.
- These regions are characterized by wet season and thus have most of the cyclonic activity through the year and this impacts the global distribution of water as the movement of the warm and cold water stakes form these regions, along with the variation in salinity.
In general, the highest relative humidity is observed NEAR SUNRISE and the lowest relative humidity is observed during MID-AFTERNOON.
Relative humidity is inversely proportional to temperature. The colder the climate, the higher the relative humidity. The hotter the temperatures outside, the lower the relative humidity.
Relative humidity increases as the air temperature falls at night and peaks at dawn.
Temperature peaks during mid-afternoon, thus relative humidity is at its lowest.
<span>1. Groundwater is the water source in the 3rd world countries. Access to drilling and pumping technologies can increase the standard of living for many villages in sub-Saharan africa.
2. Previous industrial activities have impacted groundwater sources to the point that some areas are not suitable for potable water use without extensive remediation efforts
3. Groundwater is an important source of drinking water and irrigation water in areas that are also home to natural gas production. </span>
