Describe 2 ways that we find planets orbiting other stars

Geography
1 answer:
Jobisdone [24]3 years ago
8 0

Answer:

Methods are given below.

Explanation:

1. Direct Imaging: Its directly seeing the planet itself, it's potential has increased dramatically over the past few years due to advancements in our technology.

2. Astrometry: Study of precise positioning of stars in the sky. The star is always much more massive than the planet, so the center of mass is much closer to the star, and thus the star's orbit is very tiny while the planet's orbit is much more pronounced.

3. Doppler Shift (also known as the radial velocity method) this method is based on the theorem that planet orbiting the stars have the same weight. The changes in the star spectrum and wavelength shows the brightness coming from the orbiting star.

4.  Pulsar Timing: This Is a time-bound approach to finding the planets that orbit the stars through the beam of light that the old star emits.

Explain all the types of erosion caused by water
noname [10]

Answer:

There are three types of soil erosion caused by water. They are: Sheet, Rill and Gully.

Sheet Erosion

This type of erosion takes away the top soil over a wide area thereby making it look as though it took a sheet of the top soil. As a result, this is not easy to notice at first glance because the soil from the whole area is gone so there is nothing to compare it to.

Rill Erosion

When water goes in channels and makes lines in the soil a by carrying off the soil that was previously on those lines, that is rill erosion. These channels must be shallow to be considered Rill erosion however because if they are too big, it would become gully erosion.

Gully Erosion

Gully erosion is much like Rill erosion but on a much larger scale. With gully erosion, the channels are much bigger and allow for more soil to be taken. Gully erosion can remove a lot of soil from an area. The Grand Canyon for instance was formed by Gully erosion.

A sediment deposit close to the continental rise having a coarse material overlaid by successively finer materials of nonmarine
Elza [17]

Answer:

A sediment deposit close to the continental rise having a coarse material overlaid by successively finer materials of non marine origin is called a turbidite.

.

Explanation:

Turbidity current is the movement of sediment laden water . It is caused by the high density nature of sediments . The current is prevalent in oceans and lakes and it one process that transport sediments from coastal areas to deep sea.

The sediments in the current makes the flow denser and very rapid. The rapid nature of the movement of this sediment laden water causes a kind of selective deposition in deep sea. The more coarse sediments are deposited before less coarse sediments. The sediments deposited fines upward. The coarsest sediments are found at the bottom and it fine upward.

Turbidites are sediments deposited by turbidity currents which gradually change from coarse grain to fine grain sediments. The continental rise is the boundary between continents and the deep part of the oceans. This area is usually laden with sediment deposited by turbidity current. The sediments laden water moves downhill.

Although midlatitude cyclones and tropical cyclones are both rotating weather systems, they are different in many ways. Label ea
Darya [45]

Answer:

a. Tropical cyclone

b. Tropical cyclone

c. Tropical cyclone

d. Tropical cyclones

e. Mid latitude cyclone

f. Mid latitude cyclone

g. Tropical cyclone

Explanation:

Tropical cyclone is rapidly rotating storm which destroys everything that comes in its way. It intensifies with height and usually covers smaller area.

Mid latitude cyclone is most strong form of cyclone which forms due to temperature difference, Warn air at cold front rises and create a low pressure which gives rise to cyclone.
