What is a Valley Landform: Formation and Types of Valleys


What is a Valley Landform? Valleys are the most predominant landforms on the face of the earth. They are found on virtually every continent on planet earth, along sea bottoms, and other planets. Valleys assume a wide array of forms, from broad plains to steep-sided canyons. The kind of valley created depends on numerous factors, … Read more

What is a Desert Landform: Features and Main Landforms in a Desert


What is a Desert Landform? There is a wide range of landforms on the planet. While some landforms like mountains and forests are beautiful, others such as swamps and deserts are not that pleasant. However, we as humans are lucky to have an infinite number of landforms to view. Desert, in particular, is one kind … Read more

What is a Fossil: Formation, Types and Facts


What is a Fossil? We watch documentaries and read a plethora of materials on the history of animal and plant species every single day. But how did humans discover the origins of these animals and plant species?  It was with the help of fossils. Paleontologists have been able to harness vital information from fossils to … Read more

What is a Glacier: Types, Formation and Location


What is a Glacier? Most of today’s landscapes were carved out by the extensive glaciers of the most recent ice age. The perfectly modified landscapes robustly reflect the handiwork of ice. This carving ability explains why they are known as nature’s bulldozers. Europe harbors most of the world’s glaciers. The largest glacier is eastern Antarctica’s … Read more

What is a Mineral and How do Minerals Form and it’s Properties


What is a Mineral? Many have looked at a rock and wondered how it came to be. Well, the history of rocks begun about 4.5 billion years ago, when dust and gas combined to form the very rocks that make up our beautiful planet. Rocks are the stuff of stars since they were created from … Read more

Wind Erosion: Examples and Ways to Prevent it


What is Wind Erosion? Wind erosion is a natural process where the soil is moved, carried, and transported by the force of the wind from one place to another. In order to be transported, the threshold velocity of the wind is needed. However, this depends on the size, weight, and wetness of the soil particles. … Read more

Theory and Evidence of Seafloor Spreading


The Theory of Seafloor Spreading Seafloor spreading is a geologic process where there is a gradual addition of new oceanic crust in the ocean floor through a volcanic activity while moving the older rocks away from the mid-oceanic ridge. The mid-ocean ridge is where the seafloor spreading occurs, in which tectonic plates—large slabs of Earth’s lithosphere—split … Read more

What are Geological Faults? Causes and Types of Geological Faults


What are Geological Faults? In geology, a fault is a discontinuity that is formed by fracture in the surface rocks of the Earth (up to 200 km deep) when tectonic forces exceed the resistance of the rocks. In other words, a fault is a crack in the Earth’s crust. The rupture zone has a generally well defined … Read more

What are Geological Folds? Causes and Types of Geological Folds


What Are Folds? Fold occurs when rock deforms in such a way that it bends instead of breaking. The rocks, like any other material, deform to the action of external efforts. We do not grasp this deformation, but we know when a rock is deformed. Folds come from pressure on the rocks that occur over … Read more

Types and Causes of Mass Wasting/Mass Movement of Rocks


What is Mass Wasting/Mass Movement of Rocks? Mass wasting can be defined as a geomorphic process. A geomorphic process is a natural course of weathering, erosion and deposition that causes alteration of the surface materials and landforms of the earth. Mass wasting is also known as slope movement or mass movement. It can be described as … Read more

The Rock Cycle: Igneous, Sedimentary, and Metamorphic Rocks


What is Rock? Rocks ordinarily lie everywhere on the ground of the earth. They constitute most of the landforms, as we often notice. For instance, rocks make up the mountains and most of the non-water portions of the earth’s surface. A rock is hence defined as a solid naturally occurring mass or lumps of consolidated … Read more

What is the Pacific Ring of Fire and What are Major Causes of it


What is Pacific Ring of Fire? The Pacific Ring of Fire is the terminology given to a u-shaped area that is almost forming a ring or a circle in the Pacific Ocean expanding all the way from South America and North America to Eastern Asia, New Zealand and Australia. The stretch is approximately 40,000 kilometers … Read more

What are Landforms and Major Types of Landforms on the Earth


What are Landforms? Landforms are the natural features and shapes existent on the face of the earth. Landforms possess many different physical characteristics and are spread out throughout the planet. Together, landforms constitute a specific terrain and their physical arrangement in the landscape forms what is termed as topography. The physical features of landforms include … Read more

What are the Different Layers of The Earth?


Overview of The Earth The earth is technically the 3rd planet from the sun between Venus and Mars and has an equatorial diameter of 12,755 kilometers (7926 miles) and a polar diameter of 149.6 million kilometers (92.9 million miles). The earth is in a constant state of motion as it revolves round the sun, which … Read more
