What is the point on the surface nearest the earthquake?
Geology and GeographyThe hypocenter is the point within the earth where an earthquake rupture starts. The epicenter is the point directly above it at the surface of the Earth. What is the point on the surface where the earthquake is the strongest? Surface damage In most earthquakes, the epicenter is the point where the greatest damage takes
Why is it difficult for an organism living in the rainforest to become a fossil?
GeologyIt is difficult for an organism living in a rain forest to become fossilized. The large amount of rain throughout the year causes rapid decay of dead organisms. Also, many scavengers and decomposers work quickly to break down the tissues and structures of rain forest life. 6. What are three reasons why many organisms never
When did Mt Lassen last erupt?
GeologyWill Mount Lassen erupt again? Q: Will Lassen Peak erupt again and if so, when? A: No one can say for sure or when. However, Lassen Peak is considered active because it last erupted about 100 years ago (read more). Geologically recent volcanic activity in an area is the best guide to forecasting future eruptions.
Can diamond be found in rocks?
GeologyThe diamond is the hardest natural substance known. It is found in a type of igneous rock known as kimberlite. The diamond itself is essentially a chain of carbon atoms that have crystallized. The stone’s unique hardness is a result of the densely concentrated nature of the carbon chains. What rocks can contain diamonds? kimberlite,
What method provides the most accurate estimate of a fossils age?
GeologyThe age of fossils is determined by figuring out the age of the rock in which the fossil is found. The most accurate method is radiometric dating…. What do homologous structures vestigial structures and fossils provide evidence of *? Multiple types of evidence support the theory of evolution: Homologous structures provide evidence for common ancestry,
What is the most dangerous volcanic hazard?
GeologyTephra, lahars and tsunami become the dominant fatal causes for incidents and fatalities after about 15 km (Fig. 4). Tephra fall is commonly the most widespread volcanic hazard (Jenkins et al. What hazards make volcanoes so dangerous? Several hazards may affect the area around the volcano, such as lava flows, pyroclastic flows, lahars, jökulhlaups and
What are the properties of minerals?
GeologyMost minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity. What are the 5 properties for minerals? Minerals can be identified by their color, luster, streak, cleavage, hardness, and even by their chemical composition. What are the 10 mineral properties? These include: color,
When was Harry Hess born?
GeologyWhen did Harry Hess come up with his theory? 1962 In 1962, he proposed a groundbreaking hypothesis that proved vitally important in the development of plate tectonic theory. It addressed several geologic puzzles: If the oceans have existed for at least 4 billion years, why has so little sediment accumulated on the ocean floor? Where
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 mineral is transparent?
Geologycalcitecalcite is transparent, while the gypsum is translucent and the gold is opaque. Judging how a mineral transmits light is a good step in identifying your specimen. What is an example of a transparent mineral? Typical examples of transparent or clear gems are: Rock crystal quartz. Fine quality diamond. Corundum. Which minerals are transparent to
