How can you tell which way a glacier is moving?
GeologyAt the bottom of the glacier, ice can slide over bedrock or shear subglacial sediments. Fun Fact: Ice flow direction is determined by the glacier surface: a glacier will always flow in the direction the ice is sloping. How can you tell which direction a glacier is moving? Glacier scientists often use striations to determine
Is a Drumlin erosion or deposition?
GeologyPut simply, drumlins may have formed by a successive build of sediment to create the hill (ie deposition or accretion) or pre-existing sediments may have been depleted in places leaving residual hills (ie erosion), or possibly a process that blurs these distinctions. Are drumlins erosional? ‘ Their proximity to sediment-cored (‘drift’) drumlins implied a common
Where are subduction zones found?
Geologythe Pacific Oceanall around the edge of the Pacific Ocean, offshore of Washington, Canada, Alaska, Russia, Japan and Indonesia. Called the “Ring of Fire,” these subduction zones are responsible for the world’s biggest earthquakes, the most terrible tsunamis and some of the worst volcanic eruptions. Which type of plate boundary is where subduction zones occur?
Is Dolomite good for kitchen countertops?
GeologyFAQ. Is dolomite a good material for kitchen countertops? Dolomite is harder than marble, but softer than granite, so they can scratch if safety measures are not put in place. But is the right precautions are taken, like sealing and using cutting boards, dolomite is an excellent choice for kitchen countertops. Are dolomite countertops safe?
How did ammonites live?
Geology and GeographyAmmonites lived all around the world. Like their modern-day cephalopod relations, they were exclusively ocean-dwelling. They tended to live in more shallow seas and may have had a maximum depth of about 400 metres. When did Ammonite live on Earth? Ammonites lived during the periods of Earth history known as the Jurassic and Cretaceous. Together,
How is a vent formed?
GeologyHydrothermal vents are the result of seawater percolating down through fissures in the ocean crust in the vicinity of spreading centers or subduction zones (places on Earth where two tectonic plates move away or towards one another). The cold seawater is heated by hot magma and reemerges to form the vents. How are deep sea
What are examples of mineral resources?
GeologyMineral resources can be divided into two major categories – Metallic and Nonmetallic. Metallic resources are things like Gold, Silver, Tin, Copper, Lead, Zinc, Iron, Nickel, Chromium, and Aluminum. Nonmetallic resources are things like sand, gravel, gypsum, halite, Uranium, dimension stone. What are the 3 types of mineral resources? Minerals in general have been categorized
How is copper found in nature?
GeologyNatural abundance Copper metal does occur naturally, but by far the greatest source is in minerals such as chalcopyrite and bornite. Copper is obtained from these ores and minerals by smelting, leaching and electrolysis. The major copper-producing countries are Chile, Peru and China. Where is copper most commonly found in nature? The largest copper mine
What happens when a sediment or sedimentary rock is gradually buried deeper inside Earth?
GeologyWhat happens when a sediment or sedimentary rock is gradually buried deeper inside Earth? Sediment is lithified, but rock is unchanged until metamorphism takes places at very high pressures and temperatures. Sediment is compacted, and sedimentary rock is physically weathered by fracturing. What happens when a sedimentary rock gets buried deep inside the Earth? Sedimentary
