Is Basalt a good building material?
GeologyLately, basalt fibre has attracted attention as a possible construction material due to its properties such as high modulus of elasticity, high elastic strength, corrosion resistance, high-temperature resistance, extended operating temperature range and ease of handling. Can you build with basalt? Today, basalt is commonly used as crushed aggregate in construction projects. Crushed basalt is

What type of weathering causes the formation of soil?
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. What weathering causes soil formation? The physical and chemical weathering processes that change parent material into soil include: Temperature changes — freezing

How are Stratovolcanoes made?
GeologyAn eruption of highly viscous (very sticky) magma tends to produce steep-sided volcanoes with slopes that are about 30–35°. That’s because the viscous volcanic material doesn’t flow that far from where it is erupted, so it builds up in layers forming a cone-shaped volcano known as a stratovolcano. How are most stratovolcanoes formed? A stratovolcano

What are the Sierra Nevada mountains made of?
Geologygranitic rocksMesozoic granitic rocks and Paleozoic and Mesozoic metamor phosed sedimentary and volcanic roclra. How were the Sierra mountains formed? Sierra Nevada Molten rock erupted at the surface as lava, but most solidified deep within the earth, forming the gray granitic rocks familiar to any Sierra traveler. Less than five million years ago, the range

What is the point of a geodesic dome?
GeologyGeodesic domes help saving energy The high volume-to-surface ratio allows domes to occupy 30% less surface area than traditional buildings. If you do the maths, you’ll realize it takes at least 30% less energy to heat or cool them. What is the purpose of a geodesic dome? The geodesic design is a perfect marriage of

Where can spodumene be found?
GeologySpodumene deposits are found in locations all around the world. The most notable deposits are found in Afghanistan, Brazil, Madagascar, Pakistan and the United States (California, North Carolina and South Dakota). Where is spodumene mined in the world? Australia Spodumene is a lithium aluminosilicate mineral, LiAl(SiO3)2, that occurs in granitic pegmatites. Large quantities of spodumene

What are the different types of serpentine?
GeologySerpentine generally occurs in three polymorphs: chrysotile, a fibrous variety used as asbestos; antigorite, a variety occurring in either corrugated plates or fibres; and lizardite, a very fine-grained, platy variety. How do you identify serpentinite? Serpentine rock is apple-green to black and is often mottled with light and dark colored areas. Its surfaces often have
