Answer:

on the surface rapidly

Explanation:

Obsidian glassy texture indicates that the rock formed on the surface rapidly.

Like every other magma, the condition of the environment determines how the magma cools and solidifies.

  • When magma cools rapidly, nucleation centers will be difficult to come- by ..
  • At nucleation centers, minerals aggregates and grows to form different grain sizes.
  • When rapid cooling occurs, not enough time is given for the aggregation around the nucleus.
  • This leaves a rock mass that is finely grained.

Why are ammonite fossils found in the Himalayas?
sertanlavr [38]

Answer;

This is because most likely some time a ago there use to be Ammonites living there and as they died there, they got fossilized.

Explanation;

-Fossils of a marine animal called Ammonite are found in large numbers in the Kali Gandaki river in Nepal. Ammonites were sea animals having shells - either straight or coiled. When the Tethys sea disappeared, they were caught in the shale layers of clay and transformed into fossils. This is one of the proofs that the Himalayas were indeed once under water.

irakobra [83]

Answer: Lack of energy

Explanation:

Oxygen is needed in a process known as Respiration where it is used to produce energy from glucose. This energy is what the cell uses to continue whatever functions that it carries out which are needed for the body to survive. If the cells don't get oxygen, they can't make energy and if they can't make energy, they die.

Some cells are more important than others and so will need a constant supply of oxygen. The brain for instance requires 20% of the oxygen used in the body. If the body suffers from a lack of oxygen for whatever reason, brain cells begin to die within about 4 minutes.

The brain is extremely important as it directs the body. If the cells there begin to die, the body deteriorates and the body stops engaging in certain processes due to a lack of direction from the brain. This coupled with the other cells dying around the body will lead to even more deterioration till the body dies.
