Is there man made granite?
GeologyMany of today’s countertops contain synthetic materials, but granite countertop slabs are truly a natural stone. Only “cultured granite” products consist of man-made material. Every slab of genuine granite is different and has its own one-of-a-kind pattern. Is there fake granite? Fake granite is just what it sounds like – countertops that are made to
What is a left lateral strike slip fault?
GeologyIf you were to stand on the fault and look along its length, this is a type of strike-slip fault where the left block moves toward you and the right block moves away. How can you tell the difference between right lateral and left lateral strike-slip faults? If the block opposite an observer looking across
What is the cycle of erosion and deposition?
GeologyErosion is the process by which natural forces move weathered rock and soil from one place to another. Gravity, running water, glaciers, waves, and wind all cause erosion. The material moved by erosion is sediment. Deposition occurs when the agents (wind or water) of erosion lay down sediment. What is the cycle of erosion and

Why does the Moho occur?
GeologyThe Moho is the boundary between the crust and the mantle in the earth. This is a depth where seismic waves change velocity and there is also a change in chemical composition. What causes the Moho? The Moho discontinuity occurs at an average of about 8 km below the ocean basins and 30 kilometres below
How coal is formed from dead vegetation What is this process called?
GeologyWhat is this process called? Dead remains of plants got buried under the earth millions of years ago. Due to intense heat and pressure inside the earth, they got converted into coal. The process of conversion of dead remains of plants into coal is called carbonization. What is the process called where coal is formed

How are island chains formed?
GeologyAn island chain is formed when Earth’s plates move over a hot spot. Magma is pushed through the plate and creates an underwater volcanic mountain. The mountain grows and forms an island. How can an island chain be formed by tectonic plates? The Hawaiian Islands were formed by such a hot spot occurring in the

What are Pyrometric cones used for?
GeologyPyrometric cones are used worldwide to monitor ceramic firings in industrial kilns, pottery kilns, and small hobby kilns where the consistent temperature is important to the quality of the final product being fired. Pyrometric cones measure heat-work, the effect of time, and temperature. What is the purpose of a pyrometric cone in a gas kiln
