The earth's magnetic poles have swapped places a number times. What are these shifts called? What type of scientist typically studies them? How are they detected? I​

Answers

Answer 1

Answer:

the scientist is called GALLET

Explanation:

Yves Gallet balanced on a steep rocky slope in northeast Siberia, a turquoise river leisurely wending across the undulating landscape that sprawled below. But Gallet, of France’s Institut de Physique du Globe de Paris, had his face turned toward the rocks with one goal in mind: deciphering the history of Earth’s magnetic field.

Answer 2

These shifts are called magnetic pole reversals and they are important because the Earth's magnetic field protects us from UV radiation.

What is the Earth's magnetic field?

The Earth's magnetic field is a geomagnetic field comprised of electrically charged particles that surround the Earth's planet.

The Earth's magnetic field contains a positive pole and negative pole that reversed along geological time.

In conclusion, these shifts are called magnetic pole reversals and they are important because the Earth's magnetic field protects us from UV radiation.

Marcus read that systems provide feedback, or the return of information. Feedback can either cause a change in the system or keep it stable. Melting glaciers are an example of positive feedback. Why is this considered positive feedback

Answers

Answer:

melting glaciers would let the surrounding air and land get warmer which would cause the glacier to melt faster.

Explanation:

A positive feedback causes a system to remain stable or causes a change in the system. It is the return of the information to all.

In the context, melting of the glacier is considered as a positive feedback because as the glacier melts it causes the land and the surrounding air to get warmer which makes the glacier to melt at a faster rate.

Whether a target reflects specularly or diffusely (or in between) depends on both the surface roughness of the feature and the wavelength of the incoming radiation.

Answers

Answer:

This is True

Explanation:

Wave is a disturbance or the transition of vibrating energy from one point to another. The wavelength of a wave is the distance between the vibrating peak or the crest of the wave. It is the ratio of wave velocity and frequency.

Rough and dull surfaces tend to absorb wave radiation better than shiny and reflective surfaces. The diffusion, reflection and refraction of radiation also depend on the wavelength of the wave or radiation. For example, water absorbs radiation with long wavelengths than waves with short wavelength.

7. Which two tectonic plates are separated by a mid-ocean ridge?
a. Indian-Australian and Eurasian
b. Indian-Australian and Pacific
C. North American and South American
d. North American and Eurasian

Answers

Answer:    D.

Explanation:

North American and Eurasian

The two tectonic plates that are separated by a mid- ocean ridge are North American and Eurasian. The correct option is d.  

Along the Mid Atlantic Ridge, the North American and Eurasian Plates are sliding away from one other. Between the South American and African Plates, the Ridge extends into the South Atlantic Ocean. The ocean ridge rises 2 to 3 km above the ocean floor, with a rift valley at its crest indicating where the two plates are moving apart.

The Mid Atlantic Ridge, like other ocean ridge systems, formed as a result of divergent motion between the Eurasian and North American Plates, as well as the African and South American Plates.

Imagine your family has decided to take advantage of solar power to reduce energy costs. Each of you is willing to move to make the change to solar power the best possible. You currently live in Louisiana. Where should your family move to most improve your solar energy resources? (3 points)

Southern Florida
Eastern Michigan
Northern California
Western Arizona

Answers

The correct answer is Wester Arizona

Explanation:

To improve your solar energy resources the best decision is to move to a state or zone with more daily sunlight hours for solar electric panels. The number of sunlight hours is shown in the map of the image, for example, the state of Louisiana, which is located in the Southeast of the U.S. is in green color and this indicates the number of sunlight hours for solar energy is 4.5 hours.

In this context, the zone you and your family should move to is to Western Arizona because this state is located to the Southwest of the map and all the state of Arizona is in orange, which indicates 5.5 sunligh hours (higher than in Louisiana) and a small section located in the west of  Arizona is in pink; this indicates 6 hours of sunlight (highest value in all the map.)

Describe what geological features are created at convergent, divergent, and transform plate boundaries.

Answers

Answer:

Convergent boundaries form strong earthquakes, as well as volcanic mountains or islands, when the sinking oceanic plate melts. The third type is transform boundaries, or boundaries where plates slide past each other, forming strong earthquakes. Divergent boundaries represent areas where plates are spreading apart.

Explanation:

The geographical features created at convergent, divergent, and transform plate boundaries are earthquakes, volcanoes, mountain ranges, ocean trenches, and so on.

What are geographical features?

The features of geography created by the geological process are known as geographic features. It includes volcanoes, soil erosions, channels, lobes, and so on.

In the convergent boundaries plates are moved together, in divergent boundaries plates are moved from one another, and in transform boundaries plates are moved inward towards one another.

Therefore trenches formed in convergent plates, volcanoes found in divergent plates, and island arcs found in transform plate boundaries.
