Which of the following is the best description of seafloor spreading?
A. Melted rock from Earth's mantle rises between two tectonic
plates.
O
B. The seafloor sinks into the crust.
C. One tectonic plate moves under another one.
D. The continents move closer together.

Answers

Answer 1

Answer: A. is the correct answer

Explanation: Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.

Answer 2

Seafloor spreading is drifting and spreading of the seafloor from the mid-oceanic ridges. These are places where the seafloor is the weakest and diverge into different directions.

During the spreading of the seafloor, the magma that is upwelled from the bottom of the floor is spread into two opposite directions. That is in the northern and southern direction. The seafloor spreading was discovered in the 1960s by Harry Hess. Here the molten rocks or magma rises and solidified to form plates or slabs of rocks.

Hence the option A is correct.

What are three reasons that France stopped paying for voyages
The New World appeared worthless.
0 0
The cost was too high.
They did not like exploring.
France was at war with England.

Answers

Answer:

• The New World appeared worthless.

• The cost was too high.

• France was at war with England.

Explanation:

The French had extensive holdings in North America but they didn't think these areas held much value apart from the fur trade which was largely being replaced by cotton.

The cost of financing expeditions to the new world was also quite high as well as maintaining outposts in the new world. Seeing as the French did not see much value in the place, spending all that money made little sense to them.

The third and most important reason was the war with the British. After the British won the French and Indian war, they gained the ascendancy in North America such that the French could not impose themselves anymore.

For these three reasons, the French stopped paying for voyages and eventually sold off their lands in North America.

Problem 6: The prism is made from metal, with a density of 6.6 grams per cm?. Calculate the mass of the prism.
7 mm
18 mm
35 mm
(round your answer to the nearest hundredth)

Answers

Answer:

the mass of the prism is 29.11 g

Explanation:

Given the dimensions of the prism as;

7 mm = 0.7 cm

18 mm = 1.8 cm

35 mm = 3.5 cm

volume of the prism = 0.7 cm  x   1.8 cm   x  3.5 cm

                                  = 4.41 cm³

density of the prism, ρ = 6.6 g/cm³

The mass of the prism is calculated as;

mass = density x volume

mass = 6.6 g/cm³   x  4.41 cm³

mass = 29.106 g

mass = 29.11 g

Therefore, the mass of the prism is 29.11 g

What is British Parliament?

Parliament is the legislature, or lawmaking group, in the government of the United Kingdom (Great Britain). The government leader, called the prime minister, is always a member of Parliament. This makes Britain different from the United States, which keeps Congress and the president in separate branches of government.

The House of Lords and the House of Commons are the two chambers of the current Parliament, which is bicameral ("two chambers"). The Anglo-Saxon council administrations of the eighth century saw the earliest manifestations of these two houses, albeit they weren't always united.

The Witan was a tiny council made up of clergymen, landowner lords, and other advisors that the monarch appointed to talk about the state, taxation, and other political issues. The Witan evolved into the magnum Concilium, or Great Council, as it gained additional advisors.

Mr. Green wants to teach his students about an interaction between Earth's biosphere and geosphere. Mr. Green had his

students collect soil samples from various areas of the school campus. The students noticed that the upper layer of the soil in

the wooded area of the campus was darker than the upper layer of the sandy playing field. Why would there be a difference in

color in the upper layer of the two soil samples?

A. The soil in the wooded area was made primarily of organic matter and not rock particles

B. The soil in the wooded area was made primarily of rock particles and not organic matter.

c. There is less erosion on the playing field due to fewer plants growing on the field.

D. There is more erosion in the wooded area due to more plants growing in the area,

Answers

Answer:

The correct answer is OPTION A

Explanation:

Topsoil, which is the upper layer of the soil, is high in organic matter, fertility, and soil life. Generally, the wooded area would contain more decomposed dead plants which would contribute to making the upper layer of the soil darker compared to the sandy playing field. Though the parent material is the starting point for most soil development and the color of the soil could be attributed to the type of rock particles that weathered to form the soil. However, the darker soil in the question above indicates a greater percentage of organic matter has finished the process of breaking down into humus.

While erosion could be aided generally by the soil texture and structure. Erosion could easily take place at the sandy playing field than it would at the wooded area of the campus due to the soil compactness. The coarser the soil texture the smaller is the resistance of the soil to erosion.

What is the contour interval on this map?

C. 75 ft
D. 100 ft​

Answers

The correct answer is B. 50ft

Explanation

This image is a contour line in which each line represents a cut of the terrain at a specific height, you can see that the first line has a number zero, the third line has a number 100ft and the sixth line has a number 200ft. Therefore, it can be stated that each line represents an ascent of 50 ft in height because the interval corresponds to 50 ft in height. So, line 1, 0 ft; line 2, 50 ft; line 3, 100 ft; line 4, 150 ft; line 5, 200 ft; and so on. So the correct answer is B. 50ft.
