Types of Rocks, Geologists classify rocks into three main groups: igneous rock, sedimentary rock, and metamorphic rock. Read More info with Rock Photos
Faults are primarily caused by tectonic forces such ascompression,tension, andshear. There are several types of faults, categorized based on the type of movement and the direction of stress acting on the rocks.These geological faults are responsible for earthquakes, mountain building, and other geol...
We should never forget that each person who views our landscapes photos will have their own interpretation of that scene. For instance, a beautiful sunset photo of a wave breaking over the rocks (a seascape) might have a much stronger emotional impact on someone who has never seen the ocean...
Seascape photography involves capturing different elements of the ocean, such as waves, rocks, cliffs, and the sky, in the same frame. It requires both technical skills and artistic vision to capture the essence of the sea and its surroundings. ...
commonly known as rust. Iron oxide impurities are responsible for the deep hues that set mahogany obsidian apart from other types of obsidian. These impurities can be introduced to the molten lava during the eruption process, as the magma interacts with mineral-rich rocks and sediments within the...
