 Oxygen is a colourless, doorless and tasteless gas. It changes from a gas to a liquid at the temperature of -182.96 degree Celsius the liquid formed as a slightly bluish colour. Liquid oxygen can then be solidified or frozen at a temperature of -2 18.4 degree Celsius.

 The gas has the following physical properties Easy to compress  Expand to fill containers  Occupy more space than solids or liquids 

 The physical properties of a liquid are :  Almost in compressible Fixed volume  No fixed shape  Flow from a region of higher concentration to a region of lower concentration

 The physical properties of a solid are as followed  • definite shape and volume •higher density •attractive forces are strong •diffusion into another solid is extremely slow  •high melting points

 A current is a movement of water in one direction. Some ocean currents are small and temporary while others are permanent and circulate water all around the world. There are two main types of permanent circular circulating current wind-driven currents and thermohaline circulation.  Currents come up wind driven currents come about when wind reaches out the ocean surface although it reaches to 100 to 200 metres but the flow of wind driven current Can reach to 1000 m. Wind driven currents move in large circular patterns called as gyres. Thermohaline circulation reference to huge movement of water that flows down from surface to the ocean depths and then again gradually moving forward at the same time. This comes out because of differences in body temperature and salinity with heavy, cold salty water constantly falling to the bottom of the ocean and pushing warmer, less salty water to the top. Thermohaline circulation is known as 'great Ocean conveyor belt' because it moves water...

chemical w eathering occurs when rock dissolves in water or week acids. water runs through tiny holes in lime stones and dissolves some of it. as the water runs through the holes in the rock and into the caverns, it starts the process of erosion. the water evaporates into caverns and deposits particles of rock that eventually build up to form stalactites and stalagm ites.

  it is caused by constant mechanical weathering. fast flowing water carries sediment and can move pieces of rock , which bump and break pieces off one another. Gritty sediment acts like sandpaper as it washes over the rocks. it wears away the surface, making it smooth - just like when you file your nails.

 Mechanical  weathering happens when rock is broken into smaller pieces. one way it can is when water gets into holes in the rock and then freezes, it expands: this cracks the rock. 

 Weathering occurs in three different ways: .     mechanical weathering .     chemical weathering  .     organic weathering

  weathering is when rock is broken down into smaller pieces due to atmospheric conditions.  When sediment and fragments of rock are moved from one place to another by wind or water, the process is called erosion .

The arid zone is characterized by excessive heat and inadequate, variable precipitation; however, contrasts in climate occur. In general, these climatic contrasts result from differences in temperature, the season in which rain falls, and in the degree of aridity.  

The polar zone encompasses the areas around the North and South Poles. Starting from the North Pole, this zone stretches to the Arctic Circle in the Northern Hemisphere, and reaches even further south in North America and Asia. In the Southern Hemisphere, starting from the South Pole, this zone stretches as far north as the Antarctic Circle, encompassing the whole of the continent of Antarctica.

 T he word  Tropical  specifically  means  places near the equator. The word is also sometimes used in a general sense for a  tropical  climate, a climate that is warm to hot and moist year-round. This includes  tropical  rainforests with lush vegetation. ...  Tropical  plants and animals are native to the  tropics  or the Torrid zone.  The  tropical  zone includes the Amazon Basin of Brazil, West Africa's Congo Basin and the rainforests of Malaysia and Indonesia. Large areas of South America, Africa and Asia, located between the  Tropics  of Cancer and Capricorn, have a  tropical climate .

 Climate variability includes all the variations in the climate that last longer than individual weather events, whereas the term climate change only refers to those variations that persist for a longer period of time, typically decades or mor

  Geography  is the study of places and the relationships between people and their environments. Geographers explore both the physical properties of Earth's surface and the human societies spread across it.

  Science  is the pursuit and application of knowledge and understanding of the natural and social world following a systematic methodology based on evidence.  Scientific  methodology includes the following: Objective observation: Measurement and data (possibly although not necessarily using mathematics as a tool)

It is an accurate periodic table for ease of access 💨

  An  element  is a pure substance that is made from a single type of atom.  Elements  are the building blocks for all the rest of the matter in the world. Examples of  elements  include iron, oxygen, hydrogen, gold, and helium. Atomic Number. An important number in an  element  is the atomic number.

  Democritus   was a   Greek philosopher   who was the first person to use the term atom (atomos: meaning indivisible). He thought that if you take a piece of matter and divide it and continue to divide it you will eventually come to a point where you could not divide it any more. An  atom  is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized  atoms .  Atoms  are extremely small, typically around 100 Pico meters across.  All matter consists of indivisible particles called  atoms .  Atoms  of the same element are similar in shape and mass, but differ from the  atoms  of other elements.  Atoms  cannot be created or  destroyed . 

    chemical compound  is a chemical  composed of many identical molecules  (or molecules   entities ) composed of atoms for  more than one element  held together by chemical bonds . A molecule  A  molecule consisting of atoms of only one element   is therefore not a compound.  A  chemical formula  specifies the number of atoms of each element in a compound molecule, using the standard abbreviations for the chemical elements and numerical  subscripts .

  A mixture is a substance made by combining two or more different materials in such a way that no chemical reaction occurs. A mixture can usually be separated back into its original components. Some examples of mixtures are a tossed salad, salt water and a mixed bag of M&M's candy.

  A blog specially designed for students to help them solve their daily life study issues in studying, as being moderator studilings is going to solve your issue.  yes you read it very right. Studilings is going to upload every topic subject  wise to so that you could get better understanding  of every topic you study. you would find a new article every time. there'd be a quiz or more so that you can test your skills just right here to safe your time.
