Thunder cloud develops due to high temperature and high humidity.
About the Clouds

• Clouds are an essential part of Earth’s atmosphere, consisting of tiny water droplets, ice crystals, or a mix of both, suspended in the air.
• They form when warm, moist air rises, cools, and condenses around microscopic particles like dust or pollen.
• Depending on their formation process and altitude, clouds are classified into types such as cirrus (wispy, high-altitude), cumulus (fluffy, white, low-altitude), stratus (layered, low-altitude), and nimbus (rain-producing).
• Clouds play a critical role in the water cycle, facilitating precipitation and regulating Earth’s temperature.
• They reflect solar radiation, contributing to cooling, and trap heat, affecting the greenhouse effect. Clouds are also indicators of weather conditions; for instance, towering cumulonimbus clouds signal thunderstorms, while cirrus clouds often indicate fair weather.
• Understanding clouds helps meteorologists predict weather patterns and study climate systems, showcasing their importance in maintaining Earth’s ecological and atmospheric balance.

There can be more than one great circle which can be drawn on a sphere.

The largest circle that can be drawn on the sphere surface is the great circle. The shortest distance between any two points on the sphere surface is the Great Circle distance. Historically, the Great circle is also called as an Orthodrome or Romanian Circle.

The diameter of any sphere coincides with the diameter of the great circle. The great circle is used in the navigation of ship or aircraft. The idea that is the Earth is somewhat spherical helps in navigating as we come to know for the shortest distance in the sphere

Taiga forests are characteristics of Temperate region.
The boreal forest (or "taiga") is the world's largest land biome, covering 30% of global forest area and 10% of Earth's land surface.

• The boreal ecozone principally spans eight countries in the Northern Hemisphere (Canada, China, Finland, Japan, Norway, Russia, Sweden, and the US).
• Boreal forests are dominated by coniferous trees like pine, spruce, and fir, along with some broadleaf species such as poplar and birch. They thrive in high-latitude environments.
• Contains more surface freshwater than any other biome, significantly impacting northern oceans and global climate.
• Boreal regions provide over 33% of lumber and 25% of paper exports, playing a key role in climate regulation and acting as a major carbon reservoir, rivaling tropical forests.

Minamata disease was first discovered in Minamata city in Kumamoto prefecture, Japan, in 1956. It was caused by the release of methylmercury in the industrial wastewater from the Chisso Corporation's chemical factory.

Minamata disease is a neurological condition brought on by Severe mercury poisoning. in the technical sense of the word, Minamata disease is not truly a disease; rather, it is a neurological synd rome brought on by environmental and industrial poIIution.

This indicates that the central nervous system is impacted by pollutant poisoning. Methylmercury is the specific pollutant that causes this condition. Ataxia, numbness in the hands and feet, generalized muscle weakness, loss of peripheral vision, and damage to hearing and speech are some of the signs and symptoms.

In severe cases, coma, death, paralysis, and insanity all occur within a few weeks of the commencement of symptoms. Cerebral palsy may result from a congenital type of illness that can also harm fetuses in the womb.

Shifting Cultivation is known as Ladang in Indonesia, Caingin in Philippines, Milpa in central America & Mexico, Ray in Vietnam, Taungya In Myanmar, Tamrai in Thailand, Chena in Sri Lanka, Conuco in Venezuela, Roca in Brazil, Masole in central Africa.

Permafrost Pingo (A pingo, also called a hydrolaccolith, is a mound of earth-covered ice found in the Arctic and subarctic that can reach up to 70 metres (230 ft) in height and up to 600 m (2,000 ft) in diameter. Diastrophism - Horst: A horst is a raised block of the Earth's crust that has lifted, or has remained stationary, while the land on either side has subsided.

Running water - Flood Plain (A floodplain or flood plain is an area of land adjacent to a stream or river that stretches from the banks of its channel to the base of the enclosing valley walls and experiences flooding during periods of high discharge.)

Sea waves Stack (A stack or sea stack is a geological landform consisting of a steep and often vertical column or columns of rock in the sea near a coast, formed by wave erosion.

K2 is the 2nd highest peak in the world and is located in Jammu & Kashmir.

Nanda Devi is the second highest mountain in India, and the highest located entirely within the country. It is the 23rd-highest peak in the world. It is in Uttarakhand.

Tara pahar is in Himachal Pradesh.

Kangchenjunga, also spelled Kanchenjunga, is the third highest mountain in the world, and lies partly in Nepal and partly in Sikkim, India.

Deserts, fertile plains and moderately forested mountains are the characteristics features of North-Western India.

• North-Western India: This region covers states like Rajasthan, Punjab, Haryana, Himachal Pradesh, Uttarakhand, and parts of Jammu & Kashmir. Let's look at its features:
  
  ∗ Deserts: A significant part of Rajasthan is covered by the Thar Desert, also known as the Great Indian Desert.
  
  ∗ Fertile Plains: Punjab and Haryana are part of the vast Indo-Gangetic plain, known for extremely fertile land due to the river systems (Indus and its tributaries, Ghaggar).
  
  ∗ Moderately Forested Mountains: Himachal Pradesh, Uttarakhand, and parts of Jammu & Kashmir fall in the Himalayan foothills and lower ranges. These areas have mountains covered with forests, often described as moderately forested compared to the dense tropical rainforests found elsewhere.

All the wetlands mentioned here are designated as Ramsar sites of international importance as per International wetland convention (Ramsar convention, Iran 1971).

Ramsar Site is a wetland recognized under the Ramsar Convention (1971) for its international importance in conserving biodiversity and sustaining ecological balance. These wetlands provide critical habitats for migratory birds, endangered species, and unique flora and fauna.

They help in groundwater recharge, flood control, and climate regulation, while supporting local livelihoods like fishing and agriculture. India currently has 98 Ramsar Sites spread across 28 states and union territories, highlighting the country’s rich wetland diversity.
