Geology

This guide will teach you how to estimate the classification of a soil and how to describe its characteristics, based on the Unified Soil Classification System. It is intended for use in construction materials testing but can be useful for anyone who works with soil.

Scientific use of the term "super" is rather rare, as it tends to be a superlative more often found in our common vernacular than in the annals of science. Nonetheless, geologists have assigned a set value of parameters to define the monstrous geologic events, better known as supervolcanoes.

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.

A landslide tsunami, also called a megatsunami, can be created when large amounts of earthen material slides into a body of water, creating a tsunami type wave. These waves can be much taller than a normal tsunami that usually occurs when an underwater earthquake shakes up the sea floor.

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

Carbon Capture and Storage is a important tool that tackles climate change, provides energy security, creates jobs and economic prosperity. The types of CCS are described and the technology, capture, transportation and storage are all described. This stops greenhouse gases from polluting our skies.

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.

Unique and rare Septarian brown stones among other types are found along a narrow stretch of Lake Michigan shorelines. Find out the one other place in the world they can be found.

On August 27th 1883, after a long period of relative quiet, the Krakatoa volcano located between Java and Sumatra, roared to live. During the eruption, the island mountain blew itself apart, killing over 30,000 people in the process. Today, Krakatoa is back, but in a much smaller way.

Land subsidence caused by groundwater withdrawal poses a significant threat to governments, businesses, and the general public.

Volcanoes occur where magma (molten rock) from deep inside the earth forces its way to the surface. The magma may erupt as red-hot lava, or may explode into clouds of ash and volcanic bombs. Volcanic activity also produces strange landscapes of gushing geysers, steamy lakes, and bubbling mud pools.

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.

At any point on the earth's surface, if you dig down far enough, you will come to rock. Rocks are the building blocks of the earth's crust. There are many different types of rock, and they are all composed of one or more minerals. This article explores 10 fascinating facts about rocks and minerals.

Where are the world's supervolcanoes? The Western United States, Italy, New Zealand, and Asia all contain volcanoes capable of catastrophic eruptions.

The continents are the seven huge land masses that make up most of the earth's land surface. They are always on the move, shifted around by forces deep inside the earth. The concept of moving continents is known as "continental drift". The study of these movements is called "plate tectonics".

Fascinating facts and photos featuring the most common and some more unusual stones found along Lake Michigan's shorelines. Including various types of basalt, septarian brown stones, limestone, granite, gabbro, diorite, gneiss, schist, sandstone, silt stone, mud stone, geodes, chalcedony and agate.
