In our solar system, all planets are revolved in the anticlockwise direction.  But Venus is the only planet that revolved in the clockwise direction.

How glaciers hold water

Image
  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.

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.

About Forces

Image
  There is a force that attracts all things which are living and non-living in the Universe, which is Gravitational force. The force that helps the body to float in a liquid is the Buyont force. The force which helps us to stop anything which helps us to write on  board, walk on a road,  which is Frictional force.

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.

Recent droughts in Europe were the worst in 2,100 years.

Image
  Europe has been experiencing serious dry spells and extreme heat since 2015, which has caused major droughts. Research done led by the University of Cambridge (and published on the  National Oceanic and Atmospheric Administration  website) looked at isotopes in the rings of old European Oak trees in Central Europe which formed over thousands of years to try to pin down the cause. They discovered that  the dry spells  are a "result of human-caused climate change and associated shifts in the jet stream," according to EurekAlert!

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...

The fastest gust of wind ever recorded on Earth was 253 miles per hour.

Image
  Hang on to your hats because this isn't your average wind storm. In 1996, a tropical cyclone named Olivia hit off the coast of Barrow Island, Australia with such a force that it broke an incredible record. According to  The Weather Channel , "Olivia's eyewall produced five extreme three-second wind gusts, the peak of which was a 253 mph gust," which blew past  the previous wind record  of 231 mph set in Mount Washington, New Hampshire back in 1934.
