How does the buoyant force affect a submerged object?
If the weight of the object is higher than the buoyant force the object SINKS. And the opposite happens if the weight is lower than the buoyant force. If it is equal, the object neither sink nor float, it is neutrally buoyant.
What is the hotness and coldness of air called?
every minute clouds are going higher and higher into the atmosphere , (which is extremely cold ). every minute clouds are going higher and higher into the atmosphere , (which is extremely cold ).
A law that defines right from wrong which is higher than human law is called?
Natural law
How is volcano formation different from erosion and weathering?
When a volcano forms, it forces magma (lava) out of the earth's crust. This causes the landmass (such as Hawaii) to grow because there is now more land that has been pushed out of the earth. Erosion is when something (a mountain or beach) wears away due to the weather.
State in which electrons have jumped to a higher energy level?
state in which electrons have absorbed energy and "jumped" to a higher energy level
Why is it that pahoehoe and AA lava are more frequent in shield volcanoes than in composite volcanoes?
Shield volcanoes have low viscosity basaltic lava, which typically creates pahoehoe and AA lava flows due to their ability to flow easily. Composite volcanoes have higher viscosity lava, such as andesitic or dacitic, which tend to form thicker and blockier lava flows rather than pahoehoe and AA flows.
Why do shield volcanoes happen in ocean more than on land?
Shield volcanoes produce flows of mafic lava, also called basaltic lava, which has a lower viscosity and low silica content. Oceanic crust has the same composition and so it is fairly easy for shield volcanoes to form here. Continental crust has a higher silica content. As a result, many continent based volcanoes produce much more viscous lavas which produce stratovolcanoes rather than shield volcanoes.
What type of magma did the mauna kea volcano have?
The Hawaiian Islands were formed by coalesing shield volcanoes. These volcanoes are exclusively composed of Basalt lava. The lava does not readily trap gas and flows very easily giving Mauna Loa, and Kiluaea there pronounced rounded shapes we see today.
What are the two types of magma and what makes them different?
I'm not sure... but the two different types of lava are: Viscous - sticky and slow moving, resulting in tall volcanoes Non Viscous - runny and fast moving, resulting in short and very spread out volcanoes (shield volcanoes)
Which would you expect to cause the greatest amount of contact metamorphism an intrusion of basaltic magma or an intrusion of rhyolitic magma?
An intrusion of basaltic magma would likely cause greater contact metamorphism compared to an intrusion of rhyolitic magma. Basaltic magma has higher temperatures and higher fluidity, allowing it to heat surrounding rocks more effectively and induce more intense metamorphic changes.
How is basaltic lava different from granitic lava?
Basaltic lava is far less viscous, has less silica, erupts at a higher temperature and is denser than granitic lava (properly called rhyolitic lava when it is on the surface). Basaltic lava is composed primarily of pyroxenes and calcium rich plagioclase with small amounts of olivine. Rhyolitic lava primarily contains alkali feldspars and quartz.
Where are volcanoes hidden?
Volcanoes aren't exactly hidden, but over the years, the sea level gets higher & higher, & some volcanoes go underwater, were we cannot see them at all.
Why are granitic magmas thicker than basaltic magmas?
Granitic magmas are thicker than basaltic magmas because they have higher silica content, which increases viscosity. The higher silica content leads to stronger bonding between the silica tetrahedra, making it more difficult for the magma to flow. Basaltic magmas, on the other hand, have lower silica content and are less viscous, allowing them to flow more easily.
Which type of lava-basaltic lava or rhyolitic lava flows faster and why?
Basaltic flows much faster than rhyolite. Rhyolite is higher viscosity. Find a video of a basaltic lava flow like Hawaii, it flows like water when it's hot. Rhyolite eruptions usually act more like toothpaste if they're slow, or an explosion if fast.
What is the relationship in the silicon content and the viscosity of magma?
There is an inverse relationship between magma viscosity and silicon content. Lavas erupting from basaltic volcanoes (like Hawaii) have a much lower viscosity and are much hotter than those erupted by volcanoes whose magmas are rich in silicon. There may be up to 8 orders of magnitude viscosity difference between basaltic magmas (SiO2 contents or about 45 %) and rhyolitic magmas (SiO2 > 70 %).
What is the main difference between submerged poaching and simmering?
Simmering is done at higher temperatures than a submerged poach, and can use less tender food items and larger portions.
Are Basaltic lavas are generally hotter and more viscous than andesite lavas?
No, basaltic lavas are typically hotter and less viscous than andesite lavas. Basaltic lavas have lower silica content, which results in their lower viscosity and ability to flow more easily. Andesite lavas, on the other hand, have higher silica content and are more viscous.
