How glaciers hold water

 

Glaciers and ice sheets hold about 69 percent of the world's freshwater.

Glaciers are a big item when we talk about the world's water supply. Almost 10 percent of the world's land mass is currently covered with glaciers, mostly in places like Greenland and Antarctica. You can think of a glacier as a frozen river, and like rivers, they "flow" downhill, erode the landscape, and move water along in the Earth's water cycle.

Oxygen in ocean

Image
  How much oxygen comes from the ocean? Scientists estimate that 50-80% of the oxygen production on Earth comes from the ocean. The majority of this production is from oceanic  plankton  — drifting plants, algae, and some bacteria that can photosynthesize. One particular species, Prochlorococcus, is the smallest photosynthetic organism on Earth. But  this little bacteria produces up to 20% of the oxygen in our entire biosphere . That’s a higher percentage than all of the tropical rainforests on land combined. It’s important to remember that although the ocean produces at least 50% of the oxygen on Earth, roughly the same amount is consumed by marine life. Like animals on land, marine animals use oxygen to breathe, and both plants and animals use oxygen for cellular respiration. Oxygen is also consumed when   dead plants and animals decay   in the ocean. Calculating the exact percentage of oxygen produced in the ocean is difficult because the amounts are con...

  Glaciers are a big item when we talk about the world's water supply. Almost 10 percent of the world's land mass is currently covered with glaciers, mostly in places like Greenland and Antarctica. You can think of a glacier as a frozen river, and like rivers, they "flow" downhill, erode the landscape, and move water along in the Earth's water cycle. During the maximum point of the last ice age, glaciers covered about 32 percent of the total land area. Starting around the early 14th century, and lasting to the mid-19th century, the world experienced a “Little Ice Age,” when temperatures were consistently cool enough for glaciers to advance in many areas of the world. In the United States, glaciers cover over 90,000 square kilometers (35,000 square miles). Most of those glaciers are located in Alaska, which holds 87,000 square kilometers (34,000 square miles) of glacial ice.  If all land ice melted, sea level would rise approximately 70 meters (230 feet) worldwide....

Maximum"Oxygen" producer in Earth.

Image
Our atmosphere is made up of roughly 78 per cent nitrogen and 21 per cent oxygen, with various other gases present in small amounts. The vast majority of living organisms on Earth need oxygen to survive, converting it into carbon dioxide as they breathe. Thankfully, plants continually replenish our planet’s oxygen levels through photosynthesis. During this process, carbon dioxide and water are converted into energy, releasing oxygen as a by-product. Covering 5.5 million square kilometres (2.1 million square miles), the Amazon rainforest cycles a significant proportion of the Earth’s oxygen, absorbing large quantities of carbon dioxide at the same time.

Carbon Cycle

Image
  What is the carbon cycle? Carbon is the foundation of all life on Earth, required to form complex molecules like proteins and DNA. This element is also found in our atmosphere in the form of carbon dioxide (CO2). Carbon helps to regulate the Earth’s temperature, makes all life possible, is a key ingredient in the food that sustains us, and provides a major source of the energy to fuel our global economy. The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Since our planet and its atmosphere form a closed environment, the amount of carbon in this system does not change. Where the carbon is located — in the atmosphere or on Earth — is constantly in flux. On Earth, most carbon is stored in rocks and sediments, while the rest is located in the ocean, atmosphere, and in living organisms. These are the reservoirs, or sinks, through which carbon cycles. Carbon is released back into the atmosp...

Covaxin

Image
Que. What is ‘Covaxin’ and how was it developed?   The vaccine candidate was developed by BBIL in collaboration with the National Institute of Virology (NIV). NIV isolated a strain of the novel   coronavirus   from an asymptomatic Covid-19 patient and transferred it to BBIL early in May. The firm then used it to work on developing an “inactivated” vaccine — a vaccine that uses the dead virus — at its high-containment facility in Hyderabad. “Once the vaccine is injected into a human, it has no potential to infect or replicate, since it is a killed virus. It just serves to the immune system as a dead virus and mounts an antibody response towards the virus,” said the company, adding that inactivated vaccines usually have a proven safety record.

Air pollution

 How air pollution effects our environment? Air pollution refers to the release of pollutants into the air that are detrimental to human health and the planet as a whole. “Most air pollution comes from energy use and production,” . “Burning fossil fuels releases gases and chemicals into the air.” And in an especially destructive feedback loop, air pollution not only contributes to climate change but is also exacerbated by it. “Air pollution in the form of carbon dioxide and methane raises the earth’s temperature,” . “Another type of air pollution is then worsened by that increased heat: Smog forms when the weather is warmer and there’s more ultraviolet radiation.” Climate change also increases the production of allergenic air pollutants including mold (thanks to damp conditions caused by extreme weather and increased flooding) and pollen (due to a longer pollen season and more pollen production).

The best place in the world to see rainbows is in Hawaii.

Image
  If you're an avid rainbow gazer and want to get your fill of the beautiful phenomenon, look no further than the state of Hawaii. A study published by the  American Meteorological Society  in 2021 noted that the area's "mountains produce sharp gradients in clouds and rainfall, which are key to abundant rainbow sightings." Air pollution, pollen, and a large amount of cresting waves also help to put Hawaii at the top of the list when it comes to rainbow quantity and quality.

Aerogel

Image
  What is Aerogel? ‘Aerogel’ is a broad term used to talk about an extraordinary group of materials that have been used since the 1960s in space travel, but are now finding uses across a whole range of industries. ‘Aerogel’ is not a specific mineral or material with a set chemical formula-rather, the term is used to encompass all materials with a specific geometrical structure. This structure is an extremely porous, solid foam, with high connectivity between branched structures of a few nanometres across. Though aerogel is technically a foam, it can take many different shapes and forms. The majority of aerogel is composed of silica, but carbon, iron oxide, organic polymers, semiconductor nanostructures, gold and copper can also form aerogel. However, within the aerogel structure, very little is solid material, with up to 99.8% of the structure consisting of nothing but air. This unique composition gives aerogel an almost ghostly appearance; hence it is often referred t...
