A volcano is typically found where two or more tectonic plates are either converging or diverging. The result is a rupture in the surface of the planet which then allows hot ashes, gas, and volcanic lava to rise up from the magma chamber located underneath the Earth’s surface to the atmosphere. Some of the common …
A volcano is any opening in the Earth’s surface that allows molten rock and volcanic gases to escape from far below the Earth’s surface. Although many volcanoes are mountainous in shape, a volcano can exist in nearly any form, including volcanic vents on the ocean floor, ice volcanoes, which have been found on a variety …
The rock cycle is an essential geological model that depicts the unique changes that rock undergoes during a set time period. The three major rock types are sedimentary, metamorphic and igneous. Rocks are formed and obliterated in cycles. The rock cycle depicts the formation, destruction and restoration of rocks. These changes take place due to …
A rotameter is a device that measures the flow rate of a liquid or gas in a tube. Karl Kueppers invented the rotameter in 1908, which has been widely used since then for a variety of applications. Rotameters are included in a class of devices known as “variable area meters” that depend on the substance …
Radiometric dating is a process of identifying the age of a material based on known half-lives of decaying radioactive materials found in both organic and inorganic objects. Radiometric dating is often used to determine the age of rocks, bones, and ancient artifacts. In fact, radiometric dating can be used to determine the age of the …
Sand is a sedimentary material; loose grains of worn out and disintegrated rocks. Sand is of fine granules with grains ranging between 0.06 and 2.0 mm in diameter. Sand is a naturally occurring fragmented material comprised of tiny particles of decomposed rocks, shells, or corals. So how does sand come about? As mentioned before, nature …
