The Earth is spherical in shape; it is an established fact, backed by several pieces of evidence. The equatorial circumference of the Earth is 24,897 miles, while its polar circumference is less than 83 miles than that of the equatorial circumference. This shows the Earth is not a perfect sphere. The Earth is flattened at […]

Planetary Bodies Moon The Moon is the only natural satellite of Earth and the fifth-largest moon in the solar system. It is believed to have formed after a Mars-sized body collided with Earth. It orbits Earth at a distance of approximately 239,000 miles (385,000 km). The Moon has a rocky, solid surface marked with craters

• The Sun can be considered the heart of our solar system. It is the largest object in the solar system, making up 99.8% of its mass.• The Sun’s surface temperature is about 6000°C, increasing to approximately 20 million °C in its interior.• Its surface is composed of fiery gases that leap in whirls of
In our solar system, Earth is the third planet from the Sun and the only one known to harbor life. Radiometric dating, a method used to determine the age of rocks or carbon, suggests that Earth was formed approximately 4.5 billion years ago. Earth’s gravity interacts continuously with celestial bodies, particularly the Sun and the

Endogenetic Force Endogenetic Force refers to the force generated from the Earth’s interior. It is responsible for the formation of various landforms through internal movements, and hence, it is also known as ‘constructive movement.’ These forces create landforms on the Earth’s surface, which are then transformed into flat plains by external forces, earning them the

Structure of the Himalayas The Himalayas are a unique mountain range in the form of a folded mountain chain. Due to the structural complexity in different regions and areas, no single perspective can be formed about its framework and structure. However, the general characteristics of its various tectonic units can be described. Indus-Tsangpo Suture Zone
What is the definition of a planet? Planets are solid celestial bodies that revolve around a star, such as the Sun, in elliptical orbits. Composed of rock and metal, they do not emit their own light but shine by reflecting sunlight. Unlike stars, planets are closer to Earth and do not twinkle at night. They
