The world’s ocean is crucial to heating the planet. While land areas and the atmosphere absorb some sunlight, the majority of the sun’s radiation is absorbed by the ocean. Particularly in the tropical waters around the equator, the ocean acts a as massive, heat-retaining solar panel. Earth’s atmosphere also plays a part in this process, helping to retain heat that would otherwise quickly radiate into space after sunset.
The ocean doesn't just store solar radiation; it also helps to distribute heat around the globe. When water molecules are heated, they exchange freely with the air in a process called evaporation. Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds, often vast distances. In fact, almost all rain that falls on land starts off in the ocean. The tropics are particularly rainy because heat absorption, and thus ocean evaporation, is highest in this area.
Outside of Earth’s equatorial areas, weather patterns are driven largely by ocean currents. Currents are movements of ocean water in a continuous flow, created largely by surface winds but also partly by temperature and salinity gradients, Earth’s rotation, and tides (the gravitational effects of the sun and moon). Major current systems typically flow clockwise in the northern hemisphere and counterclockwise in the southern hemisphere, in circular patterns that often trace the coastlines.
<span>Ocean currents act much like a conveyer belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth’s surface. Without currents, regional temperatures would be more extreme—super hot at the equator and frigid toward the poles—and much less of Earth’s land would be habitable.</span>
Canals are often time-consuming and expensive to build, this was a large challenge faced in building them. Also, geographical challenges and topographical challenges can often make canal building difficult.
Answer:
My bill of legistlation would contain: direction on utilization of vitality and on 'vitality generation' (which means more accentuation on green wellsprings of vitality, renewable vitality and so forth). What's more, emanation confinement for makers discharging possibly harmful items into the environment. Lastly the keep going two: direction on the utilization of chemicals underway procedures and day by day life and a great deal of support to hereditarily upgraded items which permit the expansion of harvests while restricting the requirement for pesticides for yield insurance.
Explanation:
Special triangles tell us that: 45-45-90 angles mean side ratios of 1-1-sqrt2, 30-60-90 angles have side ratios of 1-sqrt3-2.
Beginning from the upper-left corner and working clockwise:
The first side is a 45-45-90 triangle with legs of 24 in, so the hypotenuse is 24sqrt2.
The upper-right triangle is a 30-60-90, and the side opposite 30 degrees has length 24, so the hypotenuse is twice that, which is 48.
The right side is just x = 24.
The remaining three sides are identical to the first three (one from a 45-45-90 hypotenuse, another a 30-60-90 hypotenuse, and the last equal to x).
So the total perimeter is 24sqrt2 + 48 + 24 + 24sqrt2 + 48 + 24 = 144 + 48sqrt2 inches. This is choice D.
