Consider the following statements regarding one of the major geochemical cycles, the water cycle: 1. Precipitation that falls near the equator is most likely to fall as rain into the ocean. 2. Water vapor is a greenhouse gas that helps to regulate the temperature of the earth's atmosphere. 3. Globally, precipitation far exceeds evaporation. Which of the above statements is/are correct?

Consider the following statements regarding one of the major geochemical cycles, the water cycle: 1. Precipitation that falls near the equator is most likely to fall as rain into the ocean. 2. Water vapor is a greenhouse gas that helps to regulate the temperature of the earth's atmosphere. 3. Globally, precipitation far exceeds evaporation. Which of the above statements is/are correct? Correct Answer 1 and 2 only

  • Oceans cover around 70% of Earth’s surface, so most precipitation falls right back into the ocean and the cycle of evaporation and precipitation begins again.
  • The presence of water vapor in the atmosphere is one of the things that makes Earth livable.
  • Like carbon dioxide, water vapor traps heat in the atmosphere and helps keep surface air temperatures on Earth in a habitable range.
  • Temperatures on planets without water vapor in the atmosphere, like Mars, stay as low as -100° C.
  • Evaporation and precipitation are balanced over Earth's surface. In other words, if evaporation increases, precipitation also increases.

The cycle of evaporation and rain in nature can be assumed to be a kind of Carnot cycle. If ocean water instead of evaporation are boiled by the heat of Sun at a constant temperature of 100 deg C and the condensation of steam into water droplets within the clouds occur at constant temperature of -20 deg C. Find the thermal efficiency of Carnot cycle of nature?
Consider the following statements with reference to evaporation : 1. Rate of evaporation decrease with an increase in surface area. 2. Rate of evaporation increases with an Increase in temperature. 3. Rate of evaporation decreases with an increase in humidity. 4. Rate of evaporation increases with an increase in wind speed. Which of the above statement are correct?
Rearrange the given 5 sentences A, B, C, D and E in proper sequence to form a meaningful paragraph and mark the correct sequence from the given options as your answer. It is caused due to the greenhouse effect of increased level of green house gases such as carbon dioxide, CFCs, etc. There are various types of pollutants also which involved in increasing the atmospheric temperature of the earth. Water vapor is also a significant greenhouse gas which is not directly produced by humankind but involve in global warming hugely. Global warming is a gradual increase in the temperature of the earth surface and atmosphere all around the world. Increasing use of fossil fuels by the people and deforestation is increasing carbon dioxide emissions which trap heat and cause greenhouse effect.

The Amazon basin has been continuously inhabited for at least 10, 000 years, possibly more. Its earliest inhabitants were stone-age peoples, living in hundreds of far-flung tribes, some tiny, others numbering in the tens of thousands. It was from the west that Europeans explorers first arrived. In 1541 a Spanish expedition from Quito, led by Gonzalo Pizarro, ran short of supplies while exploring east of the Andes in what is today Peru. Pizarros cousin Francisco de Orellana offered to take 60 men along with the boats from the expedition and forage for supplies. De Orellana floated down the Rio Napo to its confluence with the Amazon, near Iquitos (Peru), and then to the mouth of the Amazon. Along the way his expedition suffered numerous attacks by Indians; some of the Indian warriors, they reported, were female, like the Amazons of Greek mythology, and thus the worlds greatest river got its name. No one made a serious effort to claim this sweaty territory, however, until the Portuguese built a fort near the mouth of the river at Belém in 1616, and sent Pedro Teixeira up the river to Quito and back between 1637 and 1639. During the 17th and 18th centuries, Portuguese bandeirantes (groups of roaming adventurers) penetrated ever further into the rain forest in pursuit of gold and Indian slaves, exploring as far as present-day Rondônia, and the Guaporé and Madeira river valleys. Amazonian Indians had long used the sap from rubber trees to make waterproof bags and other items. European explorers recognized the potential value of natural latex, but were unable to market it because it tended to grow soft in the heat, or brittle in the cold, and thus had limited appeal outside the rain forest. However, in 1842 American Charles Goodyear developed vulcanization (made natural rubber durable) and in 1890 Irelands John Dunlop patented pneumatic rubber tires. Soon there was an unquenchable demand for rubber in the recently industrialized USA and Europe, and the price of rubber on international markets soared. As profits skyrocketed, so did exploitation of the seringueiros, or rubber tappers, who were lured into the Amazon, mostly from the drought-stricken northeast, by the promise of prosperity only to be locked into a cruel system of virtual slavery dominated by seringalistas (owners of rubber-bearing forests). Rigged scales, hired guns, widespread illiteracy among the rubber tappers, and monopoly of sales and purchases all combined to perpetuate the workers debt and misery. In addition, seringueiros had to contend with jungle fevers, Indian attacks and all manner of deprivation.
In which year did the fort was built by Portuguese near the river Belem?
Consider the following statements regarding winds 1. The air at ITCZ rises and moves towards poles in the upper atmosphere and sinks near 30 degrees in both hemispheres and then again moves toward the equator at the surface, this cycle is known as Walker Cycle. 2. At polar latitudes the cold dense air subsides near the poles and blows towards middle latitudes as the polar easterlies. This cell is called the polar cell. Which of the statements given above is/are correct?
