Explanation :

If the trade takes place crossing the borders of a country between two or more countries , then it is called external trade. A country has to import the goods and services which are not available within the country and can export it's surplus goods and services to other countries. This process helps them fulfill each other's demands as well as earn foreign currency. Nations trade with each other due to the following reasons :

Answer:

a^2+b^2=c^2

c^2=8^2+9^2

c^2=64+81

c^2=145

c=square root of 145

c=12.04

Hypotenuse is 12 inches

Explanation:

The lengths of the legs in a right angle triangle are 8 inches and 9 inches. The length of the hypotenuse is 12 inches because the hypotenuse is equal to the sum of the squares of the lengths of the other two sides  in a right triangle.

A triangle is a geometrical shape that consists of three straight sides and three angles. It is one of the most fundamental shapes in geometry and is commonly studied in mathematics, science, and engineering.

Triangles have several properties and formulas associated with them, such as the Pythagorean theorem, The study of triangles is an essential part of geometry and has applications in many areas of mathematics and science.

In the above  right angle triangle where the  lengths of the sides are 8 inches and 9 inches, the  length of the  hypotenuse is 12 inches.

The missing data is as follows:

Local officials are concerned that agricultural fields at site B are increasing sedimentation in the river because of soil eroding from the fields. They hire an environmental consulting company to perform a study to determine if this is true. The company marks out two one-hectare plots at point B and point C in the diagram. The characteristics of the land in both plots are identical except that plot B is covered by agricultural fields and plot C is covered by undisturbed forest. Rain gauges are set up at the up-slope edge of the plots, and devices that collect eroded soil are set up along the down-slope edge of the plots. The environmental consultants hypothesize that more soil will be eroded from plot B than from plot C. Data are collected at the rain gauges and soil-collection devices at the end of each month for a year.

Answer:

To measure the precipitation or the amount of rainfall, Rain gauges is one of them which is used to collect the rainwater. The type of soil can also be determined by the various tools and kits available. By the soli and its characteristic and composition soil can help in the practice of agriculture.

At plot B the results could have been obtained by developing a rainwater harvesting system that runoff on the surface, along the downslope edge which can show the rate of sedimentation caused by erosion.

Answer:

Rain gauges collect the amount of rainfall. Also, there are several different kits that can be used in order to determine the type of soil it is. In addition to soil kits, we can also find the percentage of the types of particles that make up the soil and use a soil triangle in order to find out what type of soil it is.

Answer:

Astenosphere

Explanation:

(pls mark me as brainliest)

Scientists believe that convection currents within the asthenosphere are responsible for the movement of the plates that form the earth’s crust. Therefore option A is correct.

Located under the lithosphere, the asthenosphere is a region of the Earth's mantle that is thought to be significantly hotter and more fluid than the lithosphere. Between 100 km (60 miles) and 700 km (450 miles) below the surface of the Earth is the asthenosphere.

There are two methods to explain the strata of the Earth: chemically and physically. The crust, mantle, and core of the planet are its three chemically different layers. The soil where life can develop is part of the Earth's crust, which makes up its outermost layer.

Hence, Scientists believe that convection currents within the asthenosphere are responsible for the movement of the plates that form the earth’s crust.

Answer: Radiant Energy from the sun heats locations closest to the equator the most

Explanation:i took the test

Climate and latitude are so closely related because Radiant Energy from the sun heats locations closest to the equator the most. Thus, option 'A' is the correct option.

Seasonal temperatures of sites at various latitudes are influenced by the angle of incoming solar radiation. The incoming solar energy is more direct (almost perpendicular or closer to a 90° angle) when the sun's rays hit the surface of the Earth close to the equator. Warmer temperatures result from the solar energy being focused over a smaller surface area.

Higher latitudes have narrower solar radiation angles, which disperse energy across a broader region of the surface and result in colder temperatures. Surface temperatures are typically warmer at lower latitudes and cooler at higher latitudes because the angle of radiation changes with latitude even though higher latitudes have more hours of daylight during the summer months.

Answer:

x - y = P - Q

Explanation:

The equation of the line that is parallel to line g, will have the same slope as line g.

Find the slope of line g using two points on the line, (-3, 2) and (0, 5):

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{5 - 2}{0 - (-3)} = \frac{3}{3} = 1 [/tex]

m = 1

Point-slope equation takes the form, y - b = m(x - a), where,

(a, b) is a point the line passes through

m = slope of the line

If the line parallel to g passes through (P, Q), then the equation can be written as follows:

Substitute (a, b) = (P, Q), and m = 1 into y - b = m(x - a).

Thus:

y - Q = 1(x - P)

y - Q = x - P

Rewrite

P - Q = x - y

x - y = P - Q

Answer:

When plates move away from each other, the space between them gets filled with material, which rises to the surface, cools and forms mid-oceanic ridges. The Pacific Ocean is growing wider by about 18 cm per year as the plates diverge and the mid-oceanic ridge is built up. Where plates come into contact, energy is released. Plates sliding past each other cause friction and heat. Subducting plates melt into the mantle, and diverging plates create new crust material. Subducting plates, where one tectonic plate is being driven under another, are associated with volcanoes and earthquakes.  

When Alfred Wegener first proposed the idea of continental drift (the precursor idea to plate tectonic theory), it didn’t quite explain the full story. While he correctly showed that Africa and South America fitted together, his model wasn’t able to explain the violent forces that occur around the Earth’s crust. It wasn’t until the 1960s that a full explanation began to develop – the theory of plate tectonics.
