Earth is a giant mass of water and mud in space that formed a perfect environment for life, with the universe beginning in a tiny bubble called the cosmic egg about 15 billion years ago. The Big Bang occurred 13.8 billion years ago, leading to the creation of the universe, and Earth formed about 4.5 billion years ago from a gravitational force pulling a gas cloud.
Insights
- Earth is a giant mass of water and mud in space, providing a perfect environment for life, with its formation about 4.5 billion years ago from a gas cloud due to gravitational forces.
- Planets are round due to gravity pulling equally from all sides, with Earth being an oblate spheroid due to its rotation, and its structure consisting of the crust, mantle, outer core, and inner core, essential for understanding its composition and behavior.

"Earth's Formation, Structure, and Landforms Explained"
- Earth is a giant mass of water and mud in space, forming a perfect environment for life.
- The universe began inside a tiny bubble called the cosmic egg about 15 billion years ago.
- The Big Bang occurred about 13.8 billion years ago, leading to the creation of the universe.
- Earth formed about 4.5 billion years ago from a gravitational force pulling a gas cloud.
- The early Earth had a hot surface with seas of lava and a poisonous atmosphere.
- Water rose to the surface, forming oceans, and meteors brought more water in the form of ice.
- Volcanoes on the ocean bed blew magma, creating volcanic islands that formed Pangaea.
- Plate tectonics caused Pangaea to break apart, forming the continents we see today.
- Earth Day is observed on April 22nd annually to promote ecology and raise awareness of pollution.
- Humans have made a slight change in Earth's rotation period by accumulating vast reservoirs of water.
- Planets are round due to gravity pulling equally from all sides, creating a spherical shape.
- Earth is an oblate spheroid due to its rotation causing a bulge near the equator.
- The Earth's axis is tilted, leading to different seasons in the northern and southern hemispheres.
- The Earth's rotation creates day and night, while its revolution around the sun forms a year.
- The Earth takes 365.24 days to complete one revolution around the sun.
- The angle of the Earth's axis with the orbital plane is 66 degrees.
- Jupiter is the fastest spinning planet in our solar system.
- Humans have made a moderate change in Earth's rotation period by accumulating vast reservoirs of water.
- The Earth's structure consists of the crust, mantle, outer core, and inner core.
- The Earth's crust is about 25 miles thick and floats on the mantle.
- The mantle is about 1,800 miles thick and is made of solid and sturdy rock materials.
- The outer core is made of super hot liquid molten substance called lava.
- The inner core is a solid ball made of iron and nickel, extending 900 miles towards the center.
- The crust occupies less than one percent of Earth's volume.
- The outer core is as hot as the surface of the sun.
- The Earth's structure is essential for understanding its composition and behavior.
- Landforms are natural geographical features of the Earth classified into mountains, hills, valleys, plateaus, and plains.
- External processes like erosion and deposition shape the Earth's surface.
- Internal processes like plate tectonics and volcano eruptions occur inside the Earth's surface.
- Mountains are higher and steeper landforms formed by tectonic plate movements.
- Fold, block, and volcanic mountains are the three main types of mountains.
- Plains are flat, low relief areas suitable for human habitation and agriculture.
- Planes are formed from the sedimentation of eroded soil.
- Understanding landforms helps in appreciating the Earth's diverse geography and natural beauty.

Earth's Plateaus, Deserts, and Major Domains
- Plateaus are flat elevated landforms that rise sharply above the surrounding area on at least one side, occurring on every continent and taking up a third of the earth's land. They are divided into dissected plateaus, formed by the upward movement in the earth's crust due to tectonic plate collision, and volcanic plateaus, created by small volcanic eruptions building up over time.
- Deserts are dry areas with little vegetation due to low rainfall, with arid air and high daytime temperatures. Desertification, caused by human activities like overgrazing, deforestation, over cultivation, and poor irrigation practices, leads to the transformation of fertile land into deserts.
- The Tibetan Plateau, spanning Tibet, China, and India, is the largest plateau globally, covering 2.5 million square kilometers. Landforms can also exist underwater, such as mountain ranges and basins, with the Mariana Trench in the South Pacific Ocean being the deepest landform on earth.
- The four major domains of the earth are the lithosphere, hydrosphere, atmosphere, and biosphere, essential for life on earth. The lithosphere comprises the solid portion of the earth, divided into continental and oceanic crusts. The hydrosphere covers 71% of the earth's surface, with only 2.5% of water being consumable by humans.
- The atmosphere, composed of different layers like the troposphere, stratosphere, mesosphere, thermosphere, and exosphere, plays crucial roles in maintaining life on earth. The biosphere encompasses all areas where living organisms exist, divided into the plant and animal kingdoms, with the earth being approximately 3.7 billion years old.
