Where are the most earthquakes?
Geologythe Pacific Oceanaround the edges of the Pacific Ocean, an area known as the ‘Ring of Fire’; this where the Pacific plate is being subducted beneath the surrounding plates. The Ring of Fire is the most seismically and volcanically active zone in the world. In which 3 areas are earthquakes most common? The world’s 5
How do earthquakes work?
GeologyThe tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth’s crust and cause the shaking that we feel. What are the 3 main causes of
How sedimentary rocks are formed animation?
GeologyWhat is sediment deposition? Deposition is the laying down of sediment carried by wind, flowing water, the sea or ice. Sediment can be transported as pebbles, sand and mud, or as salts dissolved in water. What is an example of deposition of sediment? Depositional landforms are the visible evidence of processes that have deposited sediments
What are the major spheres of the atmosphere?
Geology and GeographyThese layers are the troposphere, the stratosphere, the mesosphere and the thermosphere. A further region, beginning about 500 km above the Earth’s surface, is called the exosphere. What are the 5 major spheres? The five systems of Earth (geosphere, biosphere, cryosphere, hydrosphere, and atmosphere) interact to produce the environments we are familiar with. What is
What are some interesting facts about cinder cone volcanoes?
GeologyCinder cones are the simplest and most common type of volcano. Cinder cones form over time from particles from fire fountains. Cinder cones are never huge and have a slope of around 33 degrees. They can be new volcanoes, or they can form over the vents of pre-existing volcanoes. What makes a cinder cone unique?
How do you identify greywacke?
GeologyGreywacke or graywacke (German grauwacke, signifying a grey, earthy rock) is a variety of sandstone generally characterized by its hardness, dark color, and poorly sorted angular grains of quartz, feldspar, and small rock fragments or lithic fragments set in a compact, clay-fine matrix. How do you classify sandstone? There are many different systems of classifying
Can volcanic ash be used as fertilizer?
Geology“The volcanic ash provides the surrounding soil with essential nutrients. It contains minerals that are beneficial to plants. The fine ash breaks down quickly to mix with the soil. It proves to be a good fertilizer for the crops. Is volcanic ash good for plants? The ash holds air and the air spaces it creates
What does the asthenosphere consist of?
GeologyThe Asthenosphere is made up of semi-plastic rock. Since the Lithosphere has a lower density, it floats on top of the Asthenosphere similar to the way in which an iceberg or a block of wood floats on water. The lower mantle below the Asthenosphere is more rigid and less plastic. What does the asthenosphere contain?
Do earthquakes occur in one particular climate?
GeologyWe also know that most earthquakes occur far beneath Earth’s surface, well beyond the influence of surface temperatures and conditions. Finally, we know the statistical distribution of earthquakes is approximately equal across all types of weather conditions. Is earthquake affected by climate? Melting glaciers and thermal expansion of oceans from climate change may also contribute
