  What is Atmosphere? Atmosphere is the layer of gas that surrounds a planet. It is made up of different layers such as Troposphere, Stratosphere, Mesosphere, Thermosphere and Exosphere. It also consists of gases like nitrogen, oxygen, carbon-dioxide, argon, etc. The composition of the gases present in the atmosphere is Nitrogen which is 78%, Oxygen is 21%, Argon is 0.93%, Carbon-dioxide is 0.04%, and other gases are present in very small amounts. The Atmosphere protects us form harmful UV radiations emitted by the Sun. Atmosphere scatters sunlight entering the Earth's Surface, helping in regulation of various processes such as water-cycle, regulation of temperature and other natural processes. Atmosphere protects living beings from harmful green-house gases by maintaining the optimal temperature of Earth's Surface.          Composition of the Atmosphere: There are several gases present in atmosphere such as: a) Nitrogen:  It is the most abundant ...

  A] What are Plates in geographical term? Plates are hard and rigid segments of lithosphere including the rigid upper part of mantle and oceanic-continental crust that floats on the underlying asthenosphere. The lithospheric plates move over the plastic asthenosphere under the influence of thermal convective currents. Thermal convection currents are nothing but radio energy which is created by radio-active decaying of rocks inside the core. The movement of crustal plates cause pressure and tensions upon the rock, leading to deformation of land surface. Further, these plate movements cause seismicity, volcanicity, occurrence of various landforms, formation of mountains, etc.  B] What is Plate Tectonics Theory? Plate tectonics theory is majorly based on two scientific concepts- Continental Drift and Sea-floor Spreading. Plate tectonics theory is a comprehensive scientific theory describing large-scale motion of tectonic plates of Earth's lithosphere over the Asthenosphere. The ...

  A] Concept of Rock Cycle: The rock cycle describes the processes through which three main rock types (igneous, metamorphic and sedimentary) transform from one type into another. The formation, movement and transformation of rocks results from Earth's internal heat property, pressure from tectonic processes and effects water, wind, gravity and biological activities. Through the texture of a rock it indicates the conditions under which it was formed and also tell us about the history of Earth. Different types of rocks form in Earth's various environments at or below the Earth's Surface. The uplift of land caused by Tectonic processes, exposes the rock leading to weathering and erosion. The extraction of rocks and fossil fuels, which in turn can destabilize soils, will ultimately increase erosion and decrease water quality by increasing sediments and pollutants in rivers and streams.

What are Cyclones? In meteorological terms, a cyclone is a large air mass that rotates around strong center of low atmospheric pressure. In other words, the atmospheric disturbances which involve a closed circulation around a low pressure center, anticlockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere are called as Cyclones. The early or weak phases of a cyclone are called as Tropical Depressions. Cyclones that occur in the Atlantic and North-East Pacific regions are called as hurricanes. Whereas, a cyclone occurring in the North -West Pacific region is called as Typhoons.  How are Cyclones formed? Warm and moist air over the ocean rises upwards due to less density, leaving less air near the ocean surface. As a result, it starts to create a low pressure zone. Due to the surrounding high -pressure areas, air flows into this low-pressure zone and eventually warms up, forming a cycle. With the constant heat rising above warm air and evaporation process, the e...

  World Environment Day:   World Environment Day is a global event celebrated every year on June 5th. It is an initiative led by the United Nations (UN).  It is a special day observed worldwide to focus on environmental issues.  It helps raise awareness and promote action for the protection of the environment.  It serves as a platform for communities to come together and address environmental challenges. World Environment Day aims to encourage communities to take action towards protecting the environment. It helps advocate for policy changes and promote environmental policies at local, national, and international levels. The day aims to engage young people and communities in environmental activities. World Environment Day promotes international cooperation among countries to address global environmental issues. It encourages countries to work together and share knowledge. Importance of World Environment Day: People all over the world can use World Environment Da...
