What is typically responsible for forming volcanic island chains in the oceans? Question 10 options: A) Composite volcanoes B) Fissures C) Hot spot volcanism D) Shield volcanoes

Answers

Answer:

C

Explanation:

A hot spot develops above the plume. Magma generated by the hot spot rises through the rigid plates of the lithosphere and produces active volcanoes at the Earth's surface. And as oceanic volcanoes move away from the hot spot, they cool and subside. As a result they produce older islands, atolls, and seamounts.

Answer:

Hey!

Your answer is C) Hot spot volcanism

Explanation:

Sudden, violent eruptions from Composite Volcanoes is the main reason why we see Island Chains in such odd places in our oceans!

Which type of projection is best for sorting nations by language?

Answers

Answer:

Cylindrical map projections

Explanation:

Cylindrical map projections are used for portraying the Earth. Cylindrical map projections are rectangles, but are called cylindrical because they can be rolled up and their edges mapped in a tube, or cylinder. They have straight coordinate lines with horizontal parallels crossing meridians at right angles. All meridians are equally spaced and the scale is consistent along each parallel. The only factor that distinguishes different cylindrical map projections from one another is the scale used when spacing the parallel lines on the map.

Cylindrical map projections are great for comparing latitudes to each other and are useful for teaching and visualizing the world as a whole, by determining continents, languages, etc but really aren’t the most accurate way of visualizing how the world really looks in its entirety.

Explanation:

For example, the location of the US Capitol is located about 38 miles southwest of Baltimore. Relative location can be expressed in terms of distance, travel time, or cost.

What can scientists learn from magnetic striping patterns? Select the three correct answers.(2 points)

Answers

Hello. This question is incomplete. The full question is:

What can scientists learn from magnetic striping patterns? Select the three correct answers.

1. the cause of magnetic pole reversals

2. the year the next magnetic reversal will take place

3. the location of ancient faults caused by seismic activity

4. the exact location of the next earthquake along the California coast

5. the direction plates are moving relative to each other

6. the speed of one plate as it subducts below another plate

Answer:

The direction plates are moving relative to each other

The speed of one plate as it subducts below another plate

The location of ancient faults caused by seismic activity

Explanation:

Magnetic striping patterns are very valuable systems for understanding the factors that promote polar variability of the ocean floor. This is because these systems are formed exactly by changes in this polarity, presenting lines (similar to a zebra), which allow scientists to interpret them and have valuable information about the movement of the direction plates towards each other, the speed that a plate reaches the subduz below another plate and the location and old faults that were caused by the existence of seismic activities.
