What is the definition of reverse fault in science?
GeologyDefinition of reverse fault : a geological fault in which the hanging wall appears to have been pushed up along the footwall. What is a reverse fault kid definition? A reverse fault (if steeply dipping) or thrust fault (if shallowly dipping) is a fault where the fault plane dips toward the upthrown block. It is
Is Serpentine jewelry safe?
GeologyHowever, the green serpentine gemstones most often used in jewelry making are part of the serpentine subgroup of stones known as antigorite, as this form of serpentine is safe for drilling and shaping unlike other forms such as chrysotile, which is used in asbestos. Is serpentine toxic? Serpentine is not a toxic rock. It sometimes
Is Super white quartzite or dolomite?
GeologyDolomite MarbleDolomite Marble. What is the difference between quartzite and dolomite? Unlike granite or quartzite, dolomite is a sedimentary rock, which forms naturally when limestone comes in contact with magnesium-rich groundwater and undergoes a chemical change. It comes in shades of white or gray, and usually contains streaks that allow it to resemble marble better
Is soil a product of weathering?
GeologySoils develop because of the weathering of materials on Earth’s surface, including the mechanical breakup of rocks, and the chemical weathering of minerals. Soil development is facilitated by the downward percolation of water. Is soil a weathering? Weathering describes the means by which soil, rocks and minerals are changed by physical and chemical processes into
How are plutonic igneous rocks formed?
Geology questionsPlutonic rocks are formed when magma cools and solidifies underground. Volcanic rocks are formed from lava that flows on the surface of the Earth and other planets and then cools and solidifies. The texture of an igneous rock depends on the size of the crystals in the rock. How are plutonic rocks formed? intrusive rock,
Which mass wasting process has the slowest rate of movement?
GeologySoil creep is a slow and long term mass movement. What is the slowest type of mass movement process? Creep is the slowest of all the mass movements and moves the most soil out of all the mass movements. What type of mass movement is the slowest fastest? Mass movements differ from one another based
What are the three ways that form ores?
GeologyThere are three major types of ore genesis: internal processes, hydrothermal processes, and surficial processes. Ore can accumulate through geologic activity, such as when volcanoes bring ore from deep in the planet to the surface. This is called an internal process. How are ores formed? Deposits of minerals form when a medium that contains and
Where are deep ocean trenches found?
GeologyTrenches are found on the floor of the sea; however, their common name is deep ocean trenches because they are more often found in the deepest areas of the ocean. Trenches are formed in subduction zones where tectonic plates collide. There are many known trenches that scientists continue to study. Where are deep ocean trenches
What evidence exists for active volcanoes on Venus?
GeologyEvidence of a warm interior and geologic activity dots the surface of the planet in the form of ring-like structures known as coronae, which form when plumes of hot material deep inside the planet rise through the mantle layer and crust. This is similar to the way mantle plumes formed the volcanic Hawaiian Islands. Is
Why do rocks break down?
GeologyThe water in the cracks freezes as the temperature drops below freezing. As the water freezes, it expands. This expansion exerts tremendous pressure on the surrounding rock and acts like a wedge, making cracks wider. After repeated freezing and thawing of water, the rock breaks apart. What causes rocks to break down? Water, ice, acids,
