How is the movement in the asthenosphere responsible for volcanoes and earthquakes?

Answers

Answer 1

Answer:

When plates move away from each other, the space between them gets filled with material, which rises to the surface, cools and forms mid-oceanic ridges. The Pacific Ocean is growing wider by about 18 cm per year as the plates diverge and the mid-oceanic ridge is built up. Where plates come into contact, energy is released. Plates sliding past each other cause friction and heat. Subducting plates melt into the mantle, and diverging plates create new crust material. Subducting plates, where one tectonic plate is being driven under another, are associated with volcanoes and earthquakes.  

When Alfred Wegener first proposed the idea of continental drift (the precursor idea to plate tectonic theory), it didn’t quite explain the full story. While he correctly showed that Africa and South America fitted together, his model wasn’t able to explain the violent forces that occur around the Earth’s crust. It wasn’t until the 1960s that a full explanation began to develop – the theory of plate tectonics.

17) What is the difference between a keystone and an indicator species and why are they impo
for scientists to know about?
Need help ASP!

Answers

Answer:

See explanation

Explanation:

A keystone species is a species important to the environment such that when eradicated, much of its surrounding ecosystem will take a long time to recover from the drastic changes.  For example, sea otters are a keystone species of the kelp forests in the east part of the Pacific Ocean.  When they were almost hunted to extinction for the fur trade, the ecosystem suffered kelp loss as a result of overpopulation of sea urchins, which eat kelp.

An indicator species is a species that helps scientists measure the overall health of its ecosystem.  For example, scientists have used wood stork populations in the Everglades to measure the health of it, determining whether the habitat is suitable for many other species of wading birds.

Answers

Answer:

B

Explanation:

The natural role of the restriction enzymes is to protect the cell from invading phages. The restriction enzyme is an enzyme that functions by cutting DNAs from some pre-identified sites on the DNA. They are primarily found in bacteria where they protect the cell from invasion by foreign DNA from phages.

What did the construction of the Suez Canal accomplish?
A. It provided a water route from the Mediterranean to Europe,
B. It gave the Mediterranean Sea an eastern outlet.
C. It linked the Mediterranean Sea with the Atlantic Ocean.
O
D. It opened the Mediterranean Sea to Africa.

Answers

Answer:

The Suez Canal is a man-made waterway connecting the Mediterranean Sea to the Indian Ocean via the Red Sea. It enables a more direct route for shipping between Europe and Asia, effectively allowing for passage from the North Atlantic to the Indian Ocean without having to circumnavigate the African continent.

The Mediterranean Sea an eastern outlet was the construction of the Suez Canal accomplish. The correct option is B.

What was the main reason for building the Suez Canal?

This was done to promote trade and communication between the East and the West as ships sailed from the Mediterranean, through the Nile until Zagazig, and then to the Red Sea via the Bitter Lakes, which were connected to it at the time.

It gave the Mediterranean Sea an eastern outlet. The canal connects the Mediterranean Sea to the Red Sea, which in turn provides access to the Indian Ocean and beyond.

This allowed ships to avoid the long and treacherous journey around the southern tip of Africa, which was the only route to travel between Europe and Asia prior to the canal's construction. The Suez Canal has greatly reduced the time and cost of shipping goods between these regions and has had a significant impact on world trade and the global economy.

Thus, the ideal selection is option B.

Why are most volcanoes found at plate boundaries ?

( subject science )

Answers

Answer:

Most volcanoes are found at plate boundaries because when the plates move, or pull apart, magma rises to the exterior and hardens.

More of the magma starts to spring up and becomes the lava that people see in volcanoes.

When the plates start to shift and slide, the volcano will erupt, causing earthquakes.

Which adaptations allow thermophiles, a type of bacteria, to live within the hot springs of Yellowstone National Park? (Select all that apply.)

Answers

Answer:

the ability to live in a highly acidic environment

the ability to withstand very hot temperatures

Explanation:

The main feature of Yellowstone National Park is the presence of extremely hot and acidic water. Therefore, for a bacteria to live in this environment it has to adapt quickly, exhibiting the ability to be resistant to acids and high temperatures. This allows a great resistance in the bacteria and also stimulates that they present greater solubility, higher diffusion rate and lower reaction rates.

Explain the importance of the Suez and Panama Canals.

Answers

Answer:

The Suez and Panama Canals are very important because they reduce the distance for traveling and transportation by far, and they also reduced the expenses for the same.

Explanation:

The Suez and Panama Canals are two of the most important canals in the world. Their importance can be seen mostly in economic and geopolitical aspects. The Suez Canal is connecting the Mediterranean Sea and the Red Sea, while the Panama Canal is connecting the Pacific Ocean and the Caribbean Sea.

The Suez Canal enables much faster and easier transportation of goods between Europe and Northern Africa on one side, and Asia, Eastern Africa, and Australia on the other side. Instead of circling the African continent, transportation goes through this canal which is faster and safer.

The Panama Canal is connecting the waters of the two biggest oceans in the world. Its importance for transportation of goods can be seen on both the east and west coasts of both North and South America. Through it, the opposite sides of the continents have easier and faster access toward Europe and Africa on one side, and Australia (Oceania) and Asia on the other side. The transportation is much faster and much safer as if it wasn't for this canal the South American continent would have needed to be circled, and the southern part is not safe at all because of its proximity to Antarctica.

what method is best to use in igneous rock? why?​

Answers

Answer:

Igneous rocks are one of three main types of rocks (along with sedimentary and metamorphic), and they include both intrusive and extrusive rocks.

The igneous rocks are the rocks that are formed by the solidified process of the magma rocks. It is the result of the intrusive or the extrusive magma or the fire. It is wholly related to the fire or the lava.

The igneous rocks are classified into:

Chemical/mineral composition

         felsic

         intermediate

         mafic

        ultramafic

        texture or grain size

intrusive rocks

extrusive rocks

Volcanic rocks

These are the rocks that are especially of the quality of the felsic or the intermediate. These all depend on the texture and the quality of the rocks.
