Which type of boundary forms where two continental plates collide?

1 answer:

6 0

Because the rock making up continental plates is generally lighter and less dense than oceanic rock, it is too light to get pulled under the earth and turned into magma. Instead, a collision between two continental plates crunches and folds the rock at the boundary, lifting it up and leading to the formation of mountains and mountain ranges.

<span>At some convergent boundaries, an oceanic plate collides with a continental plate. Oceanic crust tends to be denser and thinner than continental crust, so the denser oceanic crust gets bent and pulled under, or subducted, beneath the lighter and thicker continental crust. This forms what is called a subduction zone.

What was unusual about the 1986 volcano-related disaster near Lake Nyos in Cameroon? A. A volcanic eruption involved a lateral b

Grace [21]

The correct answer is - C. Volcanic derived carbon dioxide gas bubbled from the lake and suffocated people and animals nearby.

In the summer of 1986, more specifically on the August 21st, a big tragedy happened in Cameroon. The Lake Nyos, located in the northwestern part of the country experienced a limnic eruption. This eruption triggered the release of very large amounts of carbon dioxide from the lake. The exact amount of carbon dioxide that was released is debatable, and the general consensus is that it was between 100,000 and 300,000 tons of the gas, though there are suggestions that it was up to 1.6 million tons.

The gas spread around very quickly, and being heavier than the air it stuck very low. In a radius of around 25 km from the lake, lot of people and animals were suffocated. The estimates are that 1746 people died and around 3,500 livestock died, not even counting the damage that has been done to the wild animals.

Where does the Strong Nuclear Force come into play? (d) What is Cosmology?

nataly862011 [7]

Answer:

The strong nuclear force holds most ordinary matter together because it confines quarks into hadron particles such as the proton and neutron. Cosmology is a branch of astronomy that involves the origin and evolution of the universe, from the Big Bang to today and on into the future.

Explanation:

The strong nuclear force is responsible that protons in the nucleus of the atoms do not repeal each other.

QUESTION 14 Chapter 3.2.2. and Figure 3.23. In an erupting column of ash, what is the convective ascent region? a. The region in

Mamont248 [21]

Answer:

Question 14. Option b

Question 15. Option a

Question 16. option c

Explanation:

Question 14.:

Regardless of the heaviness of the Ash particles inside it blended with the hot volcanic gases, this is the light comparative with the cold encompassing air.

It rises convectively over the thrust area and is known as the convective ascent region of the emission section.

Question 15.:

Since the gravity isn't so solid on Mars and Mercury Lava streams can be thicker as a result of which they don't cool so quick when contrasted with the earth. Little cone volcanoes on Mars would tend to be in general more extensive and shorter.

Question 16.:

Cryovolcano is otherwise called the ice spring of gushing lava. What's more, cryovolcanism is a method where the ejection of magma from ice happens as opposed to rock in molten form. Cryo Magma or the cryo magma or ice volcanic liquefy are normally fluids or vapor.
