Answer:

Latitude measures how far a point is north or south of the equator.  the earth is round, distance from the equator is measured in angular degrees with the equator being 0 degrees and the northernmost point ..the North Pole -- being at 90 degrees.

A few ways of determining latitude are,

A latitude refers to as the unit of measurement, generally used to determine the position of a geographical region compared to the North Pole and the South Pole.

One can determine the latitude of any given region either by comparing their positions with the position of the North Pole. Additionally, the position of the Sun can also be compared with geographical position of any given region to determine the latitude.

Hence, the significance of latitude is aforementioned.

Answer

16[tex]\pi[/tex] or 50.24 units

Explanation:

[tex]\pi[/tex][tex]r^{2}[/tex] and r is the radius, since we know what the radius is (r ) we can put this in to an expression

[tex]\pi[/tex] · 4² = 16 units

If the answer is not 16 then its 50.24 units

Explanation:

Now 16 is the correct answer but just in case I took this a step further.

If we estimate the area by using 3.14 which is ( [tex]\pi[/tex] ) because sometimes that isn't  natural to express the area using [tex]\pi[/tex]

Answer:

The length of the diagonal of the rectangle is approximately 26.2 units.

Explanation:

From Geometry we remember that the area of the rectangle ([tex]A[/tex]), in square units, is described by this formula:

[tex]A = w\cdot l[/tex] (1)

Where:

[tex]w[/tex] - Width, in units.

[tex]l[/tex] - Length, in units.

If we know that [tex]A = 342\,u^{2}[/tex] and [tex]l = 19\,u[/tex], then the width of the rectangle is:

[tex]w = \frac{A}{l}[/tex]

[tex]w = \frac{342\,u^{2}}{19\,u}[/tex]

[tex]w = 18\,u[/tex]

And the length of the diagonal ([tex]d[/tex]), in units, is determined by the Pythagorean Theorem:

[tex]d = \sqrt{w^{2}+l^{2}}[/tex] (2)

If we know that [tex]w = 18\,u[/tex] and [tex]l = 19\,u[/tex], then the length of the diagonal is:

[tex]d = \sqrt{(18\,u)^{2} + (19\,u)^{2}}[/tex]

[tex]d \approx 26.2\,u[/tex]

The length of the diagonal of the rectangle is approximately 26.2 units.

Answer:

landslide

Explanation:

if you look closely the mountain is falling which is called a landslide

The United States and other western nations occupied Western Germany in an effort to prevent the nation from rising to military power once again, like they did prior to WWII.

The plan was proposed by Joseph Stalin, arguing that if Germany rose to power a second time (like they had with the rise of Hitler between WWI & WWII), it would threaten European and international peacetime once again. The Allies agreed that they each would occupy a specific zone in the nation and administer the country until it could be reunified.

This kept Germany as a whole weak, and dependent on each occupying force for goods, which was part of the plan. By 1948, the Allies had begun unifying their sectors to help rebuild the nation, and the occupation ended around 1952, only to lead to the division of West and East Germany, and the rise of the Cold War.

Answer:

Explanation:

Answer

a.

Explanation

since it is more smooth and rounded it is probably older due to erosion

After analyzing both pictures, one can draw the conclusion that the mountain in 'Picture B' is smooth and rounded. Thus, the statement associated with picture 'B' is correct.

Mountains may undergo a variety of changes over time. They are susceptible to wind and rain erosion as well as landslides brought on by floods. Volcanic eruptions have altered certain mountains. They could also alter as a result of tectonic plate movement and earthquakes. Erosion alone is the cause. All juvenile mountain ranges are pointy, and as they get older, they become rounded.

Mountains rise rather quickly (a few millimetres each year) until the factors that created them cease to exist. They are being destroyed by the effects of erosion even as they are growing. These processes involve water in streams, ice in glaciers, and wind-blown sand chipping away at surfaces.

Therefore, the statement 'The mountains in Picture B are smooth and rounded' is correct.

Explanation:

Answer:

The problem with this classification is clastic sedimentary rocks are not formed with organic elements, that is, they do not form with the remains of organisms, such as shells, for example

Explanation:

The student made an incorrect classification. This is because he classified a rock formed from shells as clastic sedimentary rock.

Shells are organic materials, as they are the remains of living organisms. Organic material is not capable of forming clastic sedimentary rocks, as these rocks are formed only by sediments. Remains of organisms, manage to form a type of rock called organic rock.

Answer:

Rodinia was a Neoproterozoic supercontinent that assembled 1.1–0.9 billion years ago and broke up 750–633 million years ago.

Explanation:

Valentine & Moores 1970 were probably the first to recognise a Precambrian supercontinent, which they named 'Pangaea I'.

In geology, a supercontinent is the assembly of most or all of Earth's continental blocks or cratons to form a single large landmass. However, some earth scientists use a different definition, "a grouping of formerly dispersed continents", which leaves room for interpretation and is easier to apply to Precambrian times. although at least about 75% of the continental crust then in existence has been proposed as a limit to separate supercontinents from other groupings

The greenhouse effect in simple terms is the warming of Earth's surface.

One way it can be described as a world problem is the melting of ice in Antarctica, because of global warming, the ice is slowly melting, killing lots of animals.

Another way it can be described as a world problem is that the global sea level is rising. Because of these melting ice-caps, sea level is slowly rising and could potentially flood some cities or towns in the next few years.

Answer:

There are several tectonic provinces collectively called as crystalline providences.

Explanation:

Answer:

The pressure gradient causes the air to move horizontally, forcing the air directly from a region of high pressure to a region of low pressure. The Coriolis force, however, deflects the direction of the flow of the air (to the right in the Northern Hemisphere) and causes the air to flow parallel to the isobars.
