Ocean ridges form as a result of a. slab pull b. the upwelling of magma from the asthenosphere sediment being deposited from the ocean d. all of the above​

Answers

Answer 1

Answer:

b

Explanation:

Answer 2

Ocean ridges form as a result of the upwelling of magma from the asthenosphere sediment being deposited from the ocean. The correct option is B.

Under mid-ocean ridges, a mantle that is upwelling melts. The basaltic oceanic crust is formed when the melt ascends and freezes.

How are ridge landforms formed?

Around the world, in tectonic spreading zones like the Mid-Atlantic Ridge, volcanic activity creates volcanic ridges near the spreading zone by forming new land between tectonic limits. The altitudes going away from the zone are gradually lowered by isostatic settlement and erosion.

As the Earth's tectonic plates separate, new ocean bottom is generated along divergent plate borders, which are known as mid-ocean ridges. Massive basalt volcanic eruptions result from molten rock rising to the seafloor as the plates divide.

Thus, the ideal selection is option B.

what is the pressure at a depth of 5,000 km

Answers

Answer:

The pressure increases about one atmosphere for every 10 meters of water depth. At a depth of 5,000 meters the pressure will be approximately 500 atmospheres or 500 times greater than the pressure at sea level.

Explanation:

your welcome

For every 10 meters of sea depth, the pressure rises by approximately one atmosphere. The pressure will be about 500 atmospheres, or 500 times more than the pressure at sea level, at a depth of 5,000 meters.

What do you mean by the pressure?

The physical force applied to an object is referred to as pressure. Per unit area, a perpendicular force is delivered to the surface of the objects.

F/A is the fundamental formula for pressure (Force per unit area). Pascals are a unit of pressure (Pa). Absolute, atmospheric, differential, and gauge pressures are different types of pressure.

The pressure relative to the surrounding air is referred to as gauge pressure (sometimes spelled gauge pressure). A common mechanical quantity is pressure.

Pressure is frequently expressed as the depth of a particular fluid and is typically measured by its capacity to move a column of liquid in a manometer.

Therefore, for every 10 meters of sea depth, the pressure rises by approximately one atmosphere. The pressure will be about 500 atmospheres, or 500 times more than the pressure at sea level, at a depth of 5,000 meters.

Next consider heat exchange due to sensible heat flux, including convection, which is related to the roughness of the surface. A dryland (nonirrigated) crop has approximately three times greater surface roughness than short-grass steppe. Which surface would have greater heat loss due to convection, assuming that surface temperatures are warmer than the atmosphere: a cropland or short-grass steppe

Answers

Answer:

short-grass steppe

Explanation:

As stated in the text above, a dry land (non-irrigated) crop has approximately three times greater surface roughness than the short grass steppe. Soils with greater roughness, has a great capacity to retain water not drained. This is because the aggregates of this soil are able to behave as small reservoirs, which stabilize the temperature of the soil's surface, leaving it closer to the surface of the atmosphere. This means that in this type of soil, the heat loss by convection is much less than in a short-grass steppe soil.

A ocean bottom pressure sensor will record the
wave crest passed on the surface.
pressure when

1.highest
2.lowest
3.average
4.0

Answers

Answer:

1. highest

Explanation:

Ocean bottom pressure is the sum of ocean and the mass of atmosphere above sea level. The variation in the ocean bottom pressure is the result of the combined pressure of ocean atmosphere and the weight of sea water. The sensor will record the most pressure when waves crest are at highest point.

The sensor will record the wave crest passed on the surface pressure when its highest.

What is the wave crest ?

The wave crests in the oceans refer to the point of the wave where the height of one single wave is maximum and maximum water is displaced by it. The crest is a point on the surface wave and here the dialect of medium is maximum. The lowest point is said to be known as the trough. Hence the ocean bottom pressure will record the wave crest from the surface at the highest pressure.

A student believes the identity of an unknown powder is baking soda. Which of the
following tests will be most helpful in confirming the identity of the powder?
A
Adding a small amount of vinegar to the powder
B
Dissolving the powder in a beaker of water
C
Testing the electrical conductivity of it in solution
D
Comparing the color of the powder to other powders

Answers

It is a because the student believes the identity of an unknown powder which is baking soda

In order to identify whether unknown powder is baking soda or not, adding a small amount of vinegar to the powder would be the best test as it can be observed with the given table that only the baking soda reacts with vinegar. Thus, the correct option is A). Adding a small amount of vinegar to the powder.

What is the way to identity the baking soda?

Baking soda is natural chemical that is commonly known as sodium bicarbonate. It is white in color and salt composed of a sodium cation. It often appears as a fine powder.

There are two ways to test whether the baking soda is still active or not. First, drop half teaspoon of baking soda into hot water and observe if it fizzes and forms bubbles, then it's still good. Second way, drop half teaspoon of soda into a small amount of vinegar and if it fizzes, it's still active.

Thus, it can be concluded that the baking soda reacts with the vinegar. So, in order to identify it just add small amount of vinegar to the powder.
