hopefully that helps you

Answer 2

Index fossils are fossils that can serve as chronological markers.

What are index fossils?

Fossils used to describe and identify geologic periods are called index fossils, sometimes known as guide fossils or indicator fossils (or faunal stages). Index fossils must have quick evolution, a broad geographic distribution, and a narrow vertical range. Zone fossil is another phrase used when a fossil has all the characteristics listed above but does not have a widespread geographic distribution, is restricted to a zone, and cannot be used to correlate strata.

The preserved remains of particular species can be found in sedimentary rock strata as index fossils. Geologically speaking, they either lived for a little amount of time or fully disappeared from the planet during a known extinction event. They are clearly identifiable by shape.

Answer:

Alright.

Explanation:

'2D and 3D refer to the actual dimensions in a computer workspace. 2D is "flat", using the horizontal and vertical (X and Y) dimensions, the image has only two dimensions and if turned to the side becomes a line. 3D adds the depth (Z) dimension.'

Why is the distance between two meridians at the North Pole 0 miles?

Answers

Answer:

They are meeting at the North Pole. the North Pole & South Pole are the only places where lines of longitude meet and the distance is 0 miles.

Explanation:

Unlike parallels, which are always parallel to each other, meridians converge as they approach the poles. This causes a degree of longitude to vary from approximately 69 statute miles at the Equator (a great circle) to 0 miles at the poles.

What are the problems with getting electricity in the arctic?

Answers

Answer:

The main problems with bringing electricity to the Arctic are the climate and the condition of the soil.

Explanation:

The Arctic is one of the hardest areas in the world when it comes to bringing electricity to it. While the economic factor plays a role, it is still not the crucial one, as there can be enough investments without any particular problem to set up the infrastructure. The problems are in maintaining, preserving, and stabilizing the electrical infrastructure.

The problems come mainly because of the climate and the condition of the soil. The climate is very cold which affects the amount of electricity that is delivered, but the bigger problem is the constant powerful winds that are breaking up the installations. For most of the year, the soil is frozen, which is not a great starting point, but an even bigger problem is that it defrosts in the summer, the soil is oversaturated with water and not stable at all, so the electricity polls fall or lean.

What evidence, first published by Abraham Ortelius, supports Alfred
Wegener's theory of continental drift?
A. Similar animals live in different parts of the world.
B. Sensitive instruments measure plate movement.
C. Faraway places share similar fossils.
D. The coasts of South America and Africa fit together.

Answers

Answer:

Abraham Ortelius put forward as evidence for the theory of continental drift the fact that the coasts of South America and Africa fit together.

Explanation:

A is not correct because the animals that live in the present would hardly prove anything when it comes to continental drift.

B is not correct because such instruments didn't exist during the time of Ortelius.

C is not correct because this was not a piece of evidence put out by Ortelius, but it was Wegener that did that.

D is correct because Ortelius based his theory around the shapes of the continents and that their edges seemed to fit, with the eastern coastline of South America and western coastline of Africa being the most noticeable example.

strontium-147 cut into pieces what would be the half -life of each piece?

Answers

Answer:

2.62 years

Explanation:

The half life of a material is the time taken for half of the number of radioactive atoms in a radioactive material to remain.

If a radioactive material is cut into pieces, each piece has the same half life as the whole material.

Hence, if Strontium-147 is cut into pieces, each piece will have a half life of 2.62 years, just as the whole material.

Oceanic plate being destroyed

Explanation:

The convergence at this margin between the oceanic pacific plate and the Continental South American plate causes subduction here.

At this margin, there is crustal destruction.

As the denser Pacific plate subducts under the less dense continental crust, it is increasingly destroyed. Most convergent margin of this type leads to the destruction of the crust. Usually, on an adjacent side, there is a mountain building. Basically, at this margin, the most important thing is that the crust is being destroyed.

Question 2
During a tectonic plate demonstration, a teacher pushes two pieces of clay together. What kind of plate boundary was the teacher demonstrating?
A
convergent
B
earthquake
С
equator
D
divergent

Answers

Answer:

A. convergent

Explanation:

"Tectonic plates" are very important when it comes to studying the Earth. It moves in different directions every year. There are particularly three types of movements or plate boundaries (convergent, divergent and transform).

When the tectonic plates move away from each other, it is called "divergent." When they move towards each other, it is called "convergent," just like what the teacher demonstrated above. Pushing the two pieces of clay together means she's showing the movement of the tectonic plates towards each other. When the plates slide past each other, it is called "transform."
