D. It will expand and become a red giant.
SUBMIT

Answers

Answer:

D. it will expand and become a red giant.

Explanation:

In the main phase of any star's life, hydrogen is being fused into helium inside the core. This phase takes up 90% of the star's life span, and this is the phase the sun is at now. The next phase is where it turns into a red giant. Once the hydrogen has completely turned into helium, the inert helium ash collapses on itself. Which in turn causes the core to get denser and heat up, which also expands its size. It appears red because outer surface is a lower temperature, that makes it appear red (hence the name "Red Giant")

Answer:

it will expand and become a red giant

How do you explain this arrangement of fossils? What might have happened?

Answers

Answer:Answer:

The question lacks a photo to fully answer correctly

If the fossil has its neck bent backwards towards its back, that is the common way to which dinosaurs died.

If the fossil is scattered a bit from its other linking fossil pieces, than it is most likely that the dinosaur was a meal to a predator.

Fossils that are in array but are divided clearly at a section suggests that land moved. Possibly earthquake or Pangea took place.

Answer:

El Nino is caused by the interaction between the surface of the ocean and the  atmosphere on top. It is the internal changes of volume of the ocean atmosphere system that tells when the start and end of the El Nino event will be. The physical process is hard and includes unstable air-sea interactions. The system is between warm and neutral conditions with a circle that lasts 3-4 years. Forces from volcano eruptions have nothing to do with El Nino.

Match the words with their definitions.

Answers

Answer:

fault- molten rock

sill - horizontal intrusion

uplift- natural , upward movement of rock layers

d(y)ke- vertical intrusion

Explanation:

Uplift and sill are movements of layers differing in their direction of movement, where sill is in horizontal direction and uplift is in vertical direction. Fault refers to the cracks in the earth's crust.

The geological terms can be matched with their definitions as follows:

1. diyke - molten rock

It is formed when magma or molten rock is injected into fractures or cracks in the surrounding rock and solidifies.

2. sill - horizontal intrusion

A sill is an intrusive rock formation but is characterized by its parallel orientation to the existing rock layers.

3. uplift - natural, upward movement of rock layers

Uplift refers to the vertical movement of Earth's crust, causing the elevation of a particular region. It can occur due to tectonic forces, such as the collision of continental plates or the upwelling of molten material from the mantle.

4. fault - a crack across rock layers caused by moving plates

A fault is a fracture or break in the Earth's crust along which movement has occurred. Faults can be caused by tectonic forces, such as the collision or separation of lithospheric plates.
