Rocks are naturally occurring solid materials composed of minerals. They are classified into three main types based on their formation process: 1. Igneous Rocks (Primary Rocks) Types of Igneous Rocks ✅ Intrusive (Plutonic) Igneous Rocks – Formed inside the Earth’s crust from slow cooling magma (e.g., Granite, Diorite).✅ Extrusive (Volcanic) Igneous Rocks – Formed on […]

The Earth and the Moon
The Earth is the third planet from the Sun, featuring a diameter of 12,742 km, a protective atmosphere, and a unique magnetic field. It has one natural satellite, the Moon, which orbits Earth every 27.3 days. Their relationship affects tides and eclipses, showcasing significant natural phenomena on Earth.
Motions of the Earth and Their Effects
The Earth experiences two main motions: rotation, which takes 24 hours, causing day and night, and revolution, which occurs in 365.25 days, leading to seasons. These motions also influence time zones and the Earth’s shape. Key concepts include perihelion, aphelion, solstices, and equinoxes, crucial for understanding Earth’s climate and calendar.

The solar system, formed 4.6 billion years ago, consists of the Sun, eight planets, moons, asteroids, comets, and other celestial bodies. It features inner rocky planets and outer gas giants. The Sun fuels energy through nuclear fusion. Notable elements include Pluto’s reclassification as a dwarf planet and various unique planetary characteristics.
Lithosphere
The lithosphere is Earth’s outermost solid layer, comprising the crust and upper mantle, characterized by rigid tectonic plates. It supports life, agriculture, and mineral resources, while influencing geological processes like earthquakes and volcanism. Understanding its composition and movements is vital for studies in Geography and environmental science.
