विश्व पर्यावरण दिवस   विश्व पर्यावरण दिवस के अवसर पर हमें प्राकृतिक संसाधनों के प्रति संवेदनशीलता और उनके संरक्षण के प्रति प्रतिबद्धता को मजबूत करने का समय है। इस दिवस को याद करते हुए, हमें पर्यावरण संरक्षण के लिए कदम उठाने और स्थायी समृद्धि के दिशानिर्देश निर्धारित करने का संकल्प लेना चाहिए। विश्व पर्यावरण दिवस को हर साल 5 जून को मनाया जाता है। इसकी शुरुआत 1972 में संयुक्त राष्ट्र की पर्यावरण सम्मेलन में हुई थी, जिसमें पर्यावरण संरक्षण को बढ़ावा देने के लिए एक संविधान बनाया गया था। इतिहास पर्यावरण दिवस का इतिहास 1972 में संयुक्त राष्ट्र की पर्यावरण और विकास समिति (UNEP) द्वारा स्थापित किया गया था। यह दिन प्रत्येक वर्ष 5 जून को मनाया जाता है और पर्यावरण संरक्षण की महत्वपूर्णता को जागरूक करने के लिए विश्वभर में उत्साह से मनाया जाता है। यह दिन पर्यावरण संरक्षण के लिए जागरूकता बढ़ाने, कार्यों को संबोधित करने और जागरूकता बढ़ाने का एक अच्छा मौका प्रदान करता है। आयोजन पर्यावरण दिवस के आयोजन में विभिन्न संगठन, सरकारी विभाग और समुदायों द्वारा विशेष कार्यक्रम आयोजित किए जाते हैं। इनमें प्रद...

What does tropical zone mean?(उष्णकटिबंधीय क्षेत्र का मतलब क्या होता है?)

Tropical 

 



Tropical" is a Hindi word meaning "made for summer". It is commonly used for garments or materials that provide protection and comfort against winter conditions in summer.

word tool(शब्द साधन)

The word tropic comes via Latin from the Ancient Greek trope, meaning to turn or show direction.
astronomical definition(खगोलीय परिभाषा )
"Astronomical definition" means the definition of a term, terminology, or subject matter in the field of astronomy. This word is used in the fields of science and space research.
The tropics are defined as the area between the Tropic of Cancer at 23°26′10.1″ (or 23.43614°) north in the Northern Hemisphere and the Tropic of Capricorn at 23°26′10.1″ (or 23.43614°) in the Southern Hemisphere. S; [8] These latitudes correspond to the axial tilt of the Earth.
Seasons and climate(ऋतुएं और जलवायु)
Seasons and climate are two major and related topics. Seasons reflect global change, while climate approximates a situational discretion. Climate time includes precipitation, temperature, and other aspects of the atmosphere, while seasons reflect cycles of global change such as spring, summer, fall, and snow.
Many tropical regions have both dry and wet seasons. The wet season, rainy season or green season is the time of year, lasting one or more months, when most of the average annual rainfall occurs in an area. Wet weather regions extend across parts of the tropics and subtropics, including some temperate regions. Under the Köppen climate classification, for tropical climates, a wet-season month is defined as one or more months where the average precipitation is 60 mm (2.4 in) or more. Some areas with a pronounced rainy season experience interruptions in rainfall during mid-season, when the intertropical convergence zone or monsoon trough moves poleward from its location in the middle of the warm season; Typical vegetation in these areas ranges from moist seasonal tropical forests to savannas.
However, tropical areas may not have a tropical climate. Under the Köppen climate classification, much of the region in the geographical tropics is not classified as "tropical", but rather as "arid" (arid or semi-arid), including the Sahara Desert, the Atacama Desert, and the Australian Outback. In addition, there is alpine tundra and snow-covered peaks, including Mauna Kea, Mount Kilimanjaro, Puncak Jaya, and the Andes, south to the northernmost parts of Chile and Peru.
Climate change(जलवायु परिवर्तन)
Climate change is the process in which the Earth's climate system changes its form from stability. This change occurs under the influence of various factors, such as the climate system, the planet's polar fluidity, and interplanetary and equatorial currents. As a result, climate change brings about changes in temperature, rainfall patterns, and other weather processes, which are affected in different regions. It may also cause rise in sea levels, melting of glaciers, and changes in the diversity of life.
The tropical region warmed by 0.7–0.8 °C – slightly less than the global average – but a strong El Niño made 1998 the warmest year in much of the region, with no significant temperature increase since. Climate models predict a rise of 1–2 °C by 2050 and 1–4 °C by 2100.
ecosystems(पारिस्थितिकी प्रणालियों)
Ecosystems are the systems and processes that help keep the natural environment in balance and ensure its protection. These systems act as networks between land, air, water, and life. They include a wide variety of systems, including atmospheric systems, climate systems, vegetation systems, and water management. Through these systems we can maintain the natural balance and enable environmental conservation.
In biogeography, the tropics are divided into the paleotropics (Africa, Asia, and Australia) and the neotropics (the Caribbean, Central America, and South America). Together, they are sometimes called pantropic. The system of biogeographic regions is somewhat different; The Neotropical region includes both the Neotropics and temperate South America, and the Paleotropics correspond to the Afrotropical, Indomalayan, Oceanian, and tropical Australian regions.
flora(फ्लोरा)
The word "flora" means the group of all the animals or plants that are naturally present in a particular area or more areas. This term is specifically related to vegetation, such as all the species or plants found in an area.
diseases(बीमारियाँ)
A variety of diseases can be found in tropical regions, caused by a variety of factors. These may include climate change, water scarcity, water sensitivity, seasonal changes, and natural disasters. In tropical areas, the risk of skin diseases, drainage diseases, and weakened immune systems increases due to burns or low pressure. Additionally, diseases such as dengue, malaria, diarrhea, and chikungunya may also be prevalent in tropical regions.
