Choose the correct option lowest layer of the atmosphere is

We live at the bottom of an invisible ocean called the atmosphere, a layer of gases surrounding our planet. Nitrogen and oxygen account for 99 percent of the gases in dry air, with argon, carbon dioxide, helium, neon, and other gases making up minute port ions. Water vapor and dust are also part of Earth’s atmosphere. Other planets and moons have very different atmospheres, and some have no atmospheres at all. The atmosphere is so spread out that we barely not ice it, yet its weight is equal to a layer of water more than 10 meters (34 feet) deep covering the entire planet. The bottom 30 kilometers (19 miles) of the atmosphere contains about 98 percent of its mass. The atmosphere— air—is much thinner at high altitudes. There is no atmosphere in space. Scientists say many of the gases in our atmosphere were ejected into the air by early volcanoes. At that time, there would have been little or no free oxygen surrounding Earth. Free oxygen consists of oxygen molecules not attached to another element, like carbon (to form carbon dioxide) or hydrogen (to form water). Free oxygen may have been added to the atmosphere by primitive organisms, probably bacteria, during photosynthesis. Photosynthesis is the process a plant or other autotroph uses to make food and oxygen from carbon dioxide and water. Later, more complex forms of plant life added more oxygen to the atmosphere. The oxygen in today’s atmosphere probably took millions of years to accumulate. The atmosphere acts as a giga...

The troposphere is the lowest This diagram shows some of the features of the troposphere. UCAR/Randy Russell The bottom of the troposphere is at Earth's surface. The troposphere extends upward to about 10 km (6.2 miles or about 33,000 feet) above sea level. The height of the top of the troposphere varies with latitude (it is lowest over the poles and highest at the equator) and by season (it is lower in winter and higher in summer). It can be as high as 20 km (12 miles or 65,000 feet) near the equator, and as low as 7 km (4 miles or 23,000 feet) over the poles in winter. Air is warmest at the bottom of the troposphere near ground level. Air gets colder as one rises through the troposphere. That's why the peaks of tall mountains can be snow-covered even in the summertime. Air pressure and the density of the air also decrease with altitude upward to the tropopause, which is the boundary between the troposphere and the stratosphere. Because of these decrease in air pressure with height, the cabins of high-flying jet aircraft, which fly at the top of the troposphere, or often just above the tropopause in the more stable

The troposphere is the lowest layer of the Earth's atmosphere . It starts at Earth's surface and goes up to a height of 7 to 20 km above sea level. Most types of clouds are found in this region , and almost all weather occurs within this layer. I t holds nearly all of the water vapor in the Earth's atmosphere, regulates temperature and produces weather. Hence option C is correct.
