The theory of plate tectonics grew from Alfred Wegener's theory of continental drift and incorporates modern data such as the magnetic record of the seafloor. The theory of plate tectonics helps to explain natural phenomena such as volcanic island arcs, large mountain belts, and seamount chains.
To determine the relative ages of rock units and create a timeline for geologic events in an area, geologists follow five key principles of relative dating.
This hub is solely written bearing in mind helping school kids with their assignments. I have written down briefly with illustrations where possible, what mountains are, how they are formed, the types of mountains and how you identify the different types of mountains. I hope you enjoy reading this, and it helps you with your requirements.
Ring of Fire is a common expression applied to a geographical area bordering the Pacific Ocean. Within this "Ring of Fire" earthquakes and volcanoes are more common than any other place on the planet.
This article looks at ten sandy beaches of extraordinary colour, what they are composed of and how they are formed, with illustrations of all ten
Where are the world's supervolcanoes? The Western United States, Italy, New Zealand, and Asia all contain volcanoes capable of catastrophic eruptions.
If you want to identify a mineral, you need to examine its properties. This is a guide to how scientists identify minerals by their physical properties.
The Taal Volcano of the Philippines is unusual in that it is a recently-developed volcano situated inside a much older supervolcano that is no longer active. This set-up is not unique in the natural world, for similar arrangements can be found at Crater Lake in the US and Lake Taupo in New Zealand.
A nineteenth century British woman with little education made some of the most important geological discoveries of her time.
Land subsidence caused by groundwater withdrawal poses a significant threat to governments, businesses, and the general public.
Mud is a versatile and interesting material. It's useful for both humans and animals. It can also be dangerous, especially in the form of mud volcanoes and mudflows.
What are the most dreadful earthquakes of India. Below is the list of biggest earthquakes of India with images.
This is a brief description of the structure of planet earth, written specifically to help educate curious children.
This article looks at the processes by which rocks melt and the different ways they cool and solidify to form igneous rocks.
These phrases are known by most us: Flushing it down the toilet, a diamond in the rough, a pearl in the wild. They all refer to finding value where none is expected. As it turns out, human waste contains precious metals and gems washed down the drain unconsciously during our hurried lives.
To any student of geology and natural disasters, there is no way around it, the "Ring of Fire" is the most seismic active place on the planet. About 70% of the world's volcanoes and earthquakes take place here. Nonetheless, many dangerous volcanoes can be found elsewhere around the planet.
