Why are most volcanoes found where the Earth's crust has been broken?

A. Magma is hotter along these crusts and can melt any rocks above it.
B. There are more seismic waves that cause magma to rise to the surface.
C. The broken crust creates high pressure that causes magma to rise.
D. The broken areas of the crust provide an opening where magma can travel to the surface of Earth.

Answers

Answer 1

Answer:

The broken areas of the crust provide an opening where magma can travel to the surface of Earth.

Explanation:

The locations of the vast majority of the volcanoes are along the plate boundaries, though the occasional one can be found in the interior of the plates (those are caused by hot spots). The reason why the volcanoes are mostly found along the plate boundaries is that it is there where the broken crust is found, so the magma can easily travel through them and reach the surface.

Because the crust is cracked, that means that there are gaps through it, so the very hot magma propelled by very high pressure is able to move through them and further widen them by melting the surrounding rock. As it does so, as the magma comes close to the surface, it pushes the crust up, creating a dome-like physical form on the surface. Eventually, it manages to break through the expanded crust, and from the top of it erupts, thus creating a volcano.

This diagram shows pH ranges from 0 to 14, with 7 being neutral, less than 7 as acidic, and greater than 7 being alkaline (basic). How does pollution affect the pH of a stream?

A. When the acid rain finds its way into the stream, the pH in the stream can increase.
B. When the acid rain finds its way into the stream, the pH in the stream can decrease.
C. Pollution corresponds with decreased photosynthesis, which may cause long-term stability in pH.

Answers

Answer:

B. When the acid rain finds its way into the stream, the pH in the stream can decrease.

Explanation:

The diagram shows the  pollution effect of the pH of a stream is: “When the acid rain finds its way into the stream, the pH in the stream can decrease.” Hence, Option B is correct.

What is acid rain?

Acid rain refers to precipitation that is unusually acidic, which means that it contains a lot of hydrogen ions. It can refer to rain or any other type of precipitation.

Acid rain often has a pH level between 4-5, which is lower than the neutral pH range that present in most water, including drinking water, which is between 6.5 and 8.5.

Both humans and animals experience respiratory problems as a result. Aquatic ecosystems are impacted when acid rain falls from the sky and into rivers and ponds. The pH of the stream may drop if the acid rain makes its way into it.

Therefore, Option B is correct.

Advantages and disadvantages of aerial remote sensing to space borne in terms of atmospheric disturbance

Answers

Answer:

i dont know

Explanation:

Answer:

Explanation:

Advantages of remote sensing technology:

1. Large area coverage: Remote sensing allows coverage of very large areas which enables regional surveys on a variety of themes and identification of extremely large features.

2. Remote sensing allows repetitive coverage which comes in handy when collecting data on dynamic themes such as water, agricultural fields and so on.

3. Remote sensing allows for easy collection of data over a variety of scales and resolutions.

4. A single image captured through remote sensing can be analyzed and interpreted for use in various applications and purposes. There is no limitation on the extent of information that can be gathered from a single remotely sensed image.

5. Remotely sensed data can easily be processed and analyzed fast using a computer and the data utilized for various purposes.

Disadvantages of remote sensing:

1. Remote sensing is a fairly expensive method of analysis especially when measuring or analyzing smaller areas.

2. Remote sensing requires a special kind of training to analyze the images. It is therefore expensive in the long run to use remote sensing technology since extra training must be accorded to the users of the technology.

3. It is expensive to analyze repetitive photographs if there is need to analyze different aspects of the photography features.

4. It is humans who select what sensor needs to be used to collect the data, specify the resolution of the data and calibration of the sensor, select the platform that will carry the sensor and determine when the data will be collected. Because of this, it is easier to introduce human error in this kind of analysis.

5. Powerful active remote sensing systems such as radars that emit their own electromagnetic radiation

determine the volume of a right rectangular pyramid with the base dimensions 6 ft by 12 ft. For each triangular face, the equal sides have length 18 ft.​ Write answer to nearest cubic ft.​

Answers

9514 1404 393

Answer:

  401 ft³

Explanation:

Consider the cross section perpendicular to the base through opposite corners of the base. It will be an isosceles triangle with legs of 18 ft and a base dimension equal to the diagonal of the base rectangle.

That diagonal length is given by the Pythagorean theorem as ...

  d² = 6² +12² = 180

  d = √180 = 6√5

Then the right triangle that tells us the height of the pyramid has a base length of (1/2)(6√5) and a hypotenuse of 18. The pyramid height is ...

  (3√5)² + h² = 18²

  h = √(324 -45) = √279 = 3√31

So, the volume of the pyramid is ...

  V = (1/3)Bh

  V = (1/3)((6 ft)(12 ft))(3√31 ft) = 72√31 ft³ ≈ 401 ft³

Answer:

401 ft³

Which other pairs of segments have lengths in the same ratio as RS to PQ? Select all that apply.

Answers

Answer:

The answer is below

Explanation:

Two triangles are said to be similar to each other if the ratio of their corresponding sides are in the same proportion.

Given triangle ORS and triangle OPQ. ∠ROS = ∠POQ

∠ORS = ∠OPQ (corresponding angles are equal). Also, ∠OSR = ∠OQP (corresponding angles are equal)

Therefore using angle angle similarity theorem, we can say triangle ORS is similar to triangle OPQ.

Therefore:

ratio of RS to PQ = ratio of OR to OP = ratio of OS to OQ

Let O, P, and Q be distinct collinear points with PQ=3. Let P′ and Q′ be the images of points P and Q under dilation from point O with scale factor 4.

What is the length of the image segment P′Q′?

Answers

Given:

O, P, and Q be distinct collinear points with PQ=3.

P′ and Q′ be the images of points P and Q under dilation from point O with scale factor 4.

To find:

The length of the image segment P'Q'.

Solution:

We know that,

[tex]\text{Scale factor}=\dfrac{\text{Side length of image}}{\text{Corresponding side of original figure}}[/tex]

P′ and Q′ be the images of points P and Q under dilation from point O with scale factor 4. So, Segment P'Q' is the image of segment PQ and the scale factor is 4.

[tex]4=\dfrac{P'Q'}{PQ}[/tex]

It is given that PQ=3.

[tex]4=\dfrac{P'Q'}{3}[/tex]

Multiply both sides by 3.

[tex]4\times 3=P'Q'[/tex]

[tex]12=P'Q'[/tex]

Therefore, the length of the image segment P'Q' is 12 units.

A segment in the image is proportionally longer or shorter than the corresponding one in the pre-image.

The length of the image segment P′Q′

Given Information:

O, P, and Q be distinct collinear points with PQ=3.Dilation from point O with scale factor 4.

Solution:

Scale factor=Side length of image/corresponding side of original figure

Segment P'Q' is the image of segment PQ and the scale factor is 4.

4=P'Q'/ PQ

It is given that PQ=3

4=P'Q'/3

Multiply both sides by 3.

4*3=P'Q'

12=P'Q'

Therefore, the length of the image segment P'Q' is 12 units.
