Is Brown Fantasy quartzite or marble?

Fantasy Brown is definitely not a granite. It is not a hard quartzite either. Fantasy Brown is marble, but there is more to it; Fantasy Brown is harder than regular marble because it went through the dolomitization process. Is brown quartzite a fantasy? Technically, it is a combination of marble and quartzite. According to the

In what landscape region is Mt Marcy found?

Mount Marcy, peak in the Adirondack Mountains and the highest point in New York, U.S., reaching an elevation of 5,344 feet (1,629 metres) above sea level. It lies in west-central Essex county in the northeastern part of the state, about 12 miles (19 km) south-southeast of Lake Placid village. What is the landscape region of

Why does fumigation plume occur?

The atmospheric stability and a smoke plume shape – Fumigation. The smoke plumes are blocked by inversion, pollution reaches the earth’s surface. This situation occurs when the ground-level atmosphere is unstable and there is a stable atmosphere just above the chimney outlet, associated e.g. with temperature inversion. What causes fumigation in plume Behaviour? Fumigation and

How did the Lechuguilla caves form?

Lechuguilla is a hypogenic cave formed by acids originating in the subsurface. It was formed by the oxidization of hydrogen sulfide (H[2]S) released from connate water at the water table. This H[2]S was absorbed into oxygenated water on bedrock surfaces where it oxidized to sulfur and sulfuric acid. When was Lechuguilla Cave formed? between four

Is andesitic lava viscous?

Andesitic lava is an example of a high viscosity lava whereas balastic lava has a low viscosity, so is more runny. High silica content in the andesitic lava contributes to causing this high viscosity and low silica content in the basaltic lava means it is of a lower viscosity. Is andesitic magma viscous? Andesitic magmas,

Which is worse a deep or shallow earthquake?

Shallow quakes generally tend to be more damaging than deeper quakes. Seismic waves from deep quakes have to travel farther to the surface, losing energy along the way. Is a deeper earthquakes more powerful? The strength of shaking from an earthquake diminishes with increasing distance from the earthquake’s source, so the strength of shaking at

What type of stress causes earthquakes?

Shear stress usually happens when two plates rub against each other as they move in opposite directions. The friction of a shear stress at the edges of the plate can cause earthquakes. What causes the stress to create earthquakes? Earthquakes are the result of sudden movement along faults within the Earth. The movement releases stored-up

What was the significance of Mary Leakey discovery of the Laetoli footprints?

In 1978, Leakey’s 1976 discovery of hominin tracks—”The Laetoli Footprints”—provided convincing evidence of bipedalism in Pliocene hominins and gained significant recognition by both scientists and laymen. What is the significance of the footprints found at Laetoli? The Laetoli footprints provide a clear snapshot of an early hominin bipedal gait that probably involved a limb posture

What are the different layers of the earth answer?

Generally speaking, Earth has 4 layers: The outer crust that we live on. The plastic-like mantle. The liquid outer core. The solid inner core. What are different layers of the earth? ​​The earth is made up of three different layers: the crust, the mantle and the core. What are the layers of the earth answer?

What are three volcanic features?

Landform-scale, volcanic geomorphologic features include lava flows and related features (diverse types of scarps, levees, and lava flow surface features); lahars, calderas, the diverse types of cones and related rims, necks, domes, tubes, trenches, fissures and scarps. What are the 3 volcanic features? There are three places that volcanism commonly occurs. These are at hot
