There are two different type of sources of information about the Interior. The first one is indirect information, which means that they show data in a way that gives us an idea about the Interior, but they don’t give direct measurements. These sources are useful in determining what might be inside our planet. The other […]

The origin of life on Earth is a controversial topic in the natural sciences. The current widely-accepted scientific theory about the origins of life on Earth is known as the nebular hypothesis, or simply out of equilibrium chemistry. Perhaps the most fundamental and at the same time the least understood biological problem is the origin

It is not very likely that the total amount of water at Earth’s surface has changed significantly over geologic time. Based on the ages of meteorites, Earth is thought to be 4.6 billion years old. The oldest rocks known are 3.9 billion to 4.0 billion years old, and these rocks, though altered by post-depositional processes,

The Lithosphere is the outermost layer of the Earth. The lithosphere is divided into two parts namely the crust and the uppermost part of the mantle. Our planet has an outer solid, rocky layer which has all its plates moving on top of it continuously. They are called tectonic plates. They are located under the

The earth has a layered structure. From the outermost end of the atmosphere to the centre of the earth, the material that exists is not uniform. This is because it has a layered structure. The materials found in these layers are not uniform in their composition and density. From the surface to deeper depths, the

The Moon is Earth’s only natural satellite and the fifth largest moon in the solar system. The Moon’s presence helps stabilize our planet’s wobble and moderate our climate. The Moon’s distance from Earth is about 240,000 miles (385,000km). The Moon has a very thin atmosphere called an exosphere. The Moon’s surface is cratered and pitted

Many of us have wondered what is our solar system structure, and why is it the way it is. There are eight planets orbiting our sun in a relatively stable and regular position. The planetary orbits have been set so as to produce a balance called the force equilibrium which helps to avoid collisions with

Early Theories The Nebular Hypothesis, originally proposed by Immanuel Kant was the first scientific hypothesis for the origin of the Solar System. The ‘nebula’ referred to is the vast cloudy interstellar medium that consists of gas and dust, in which new stars are born. This hypothesis considered that the planets were formed out of a

Geography is divided into two main branches: human geography and physical geography. There are additional branches in geography such as regional geography, cartography, and integrated geography. Integrated geography combines physical and human geography by taking into account all natural systems, especially the interactions between them. Physical geography focuses on the inclusive processes that shape landform

Geography is concerned with the Description and explanation of the areal differentiation of the earth’s surface. Now, whether you think that sentence was creative, entertaining or even poetic, it’s certainly accurate. Geography is an all-encompassing discipline that focuses on the characteristics of both natural and human phenomena that are related to space. Landforms provide the
