Draw graticules for azimuthal equidistant projection using the following data: Radius of the earth: 1: 635,000,000 Scale: 1: 200, 000,000 Longitudinal interval: 30⁰ Longitudinal extent: 0° - 360° Radius of parallel 50º N = Radius of parallel 70° N= Latitudinal interval: 10⁰ Latitudinal extent: 30° N - 90° N. Radius of parallel 600 N= Radius of parallel 800 N=​

Answers

The Radius of parallel 80º N based on the information is 105,664,862.

How to explain the information

It should be noted that to draw graticules for azimuthal equidistant projection, we need to first determine the scale factor, which is the ratio of the actual size of the earth to the size on the map.

Scale factor = 1/200,000,000

Next, we need to determine the distance between each latitude and longitude line. For the longitudinal interval of 30⁰, we divide 360⁰ by 30⁰ to get 12 lines.

For the latitudinal interval of 10⁰, we subtract the latitudinal extent of 30° N from 90° N to get 60° of latitude. We then divide 60° by 10⁰ to get 6 lines.

We also need to determine the radius of each parallel. Since the radius of the earth is given as 635,000,000, we can calculate the radius of each parallel using the formula:

Radius of parallel = Radius of earth * cos(latitude)

For latitude 50° N:

Radius of parallel 50º N = 635,000,000 * cos(50°) = 452,242,300

For latitude 70° N:

Radius of parallel 70º N = 635,000,000 * cos(70°) = 222,560,702

For latitude 60° N:

Radius of parallel 60º N = 635,000,000 * cos(60°) = 318,198,051

For latitude 80° N:

Radius of parallel 80º N = 635,000,000 * cos(80°) = 105,664,862

draw a network of Simple Cylindrical Projection for the v globe on the scale of 1:400, 000, 00 (spacing parallels and meridians at 30° interval, radius of earth is 635,000,000 cm (radius of a perfect circle). A. What is reduced radius of the earth? B. Calculate the length (circumference) of the e earth ation for the whole globe on the scale a​

Answers

The length on the map based on the information will be 100,530.97 cm.

How to calculate the length

First, let's calculate the reduced radius of the earth (r). The reduced radius is the radius of a sphere that has the same volume as the oblate spheroid shape of the earth. We can calculate it using the following formula:

r = (2a + b) / 3

Where a is the equatorial radius (the radius at the equator) and b is the polar radius (the radius at the poles). For the given parameters, a = 6,350,000 cm and b = 6,314,000 cm. Therefore:

r = (2 x 6,350,000 cm + 6,314,000 cm) / 3 = 6,336,333.33 cm

Now, let's calculate the spacing between the parallels and meridians on the map. We are given that the spacing is 30°, which means that every 30° of longitude or latitude, we will have a line on the map. Since the earth's circumference is 2πr, we can calculate the distance between two lines of longitude or latitude using the following formula:

Distance = (2πr / 360) x spacing

For the given parameters, the distance between two lines will be:

Distance = (2π x 6,336,333.33 cm / 360) x 30 = 350,930.54 cm

Finally, we can calculate the length (circumference) of the earth on the given scale of 1:400,000,000. The length of the earth on the map will be:

Length on map = Length of earth / Scale

We know that the length of the earth is its circumference, which is 2πr. Therefore:

Length on map = 2πr / Scale

For the given parameters, the length on the map will be:

Length on map = 2π x 6,336,333.33 cm / 400,000,000 = 100,530.97 cm

At what depth range below the earth's surface is the asthenosphere located?

Answers

Answer: The asthenosphere is located approximately 80-200 km below the Earth's surface.

Explanation: The asthenosphere is located in the mantle of the Earth, which lies below the Earth's crust. More specifically, the asthenosphere is located in the upper mantle, at a depth range of approximately 80-200 km (50-120 miles) below the Earth's surface.The mantle itself is also divided into other layers, including the upper mantle, the transition zone, and the lower mantle. The asthenosphere is part of the upper mantle and is characterized by its viscous, plastic-like behavior, which allows for the movement of tectonic plates.Therefore, the asthenosphere is located approximately 80-200 km below the Earth's surface.

A bag contains 5 red marbles, 6 blue marbles and 3 green marbles. If three marbles are drawn out of the bag, what is the probability that all three marbles drawn will be red?

Answers

The probability of drawing three red marbles out of the bag is 5/182 or approximately 0.0275.

How to find the probability that all three marbles drawn will be red

To find the probability of drawing three red marbles out of the bag, we need to first find the total number of ways in which three marbles can be drawn from the bag, and then find the number of ways in which three red marbles can be drawn.

The total number of ways in which three marbles can be drawn from the bag is:

14C3 = (14!/(3!11!)) = 364

Where 14 is the total number of marbles in the bag.

The number of ways in which three red marbles can be drawn is:

5C3 = (5!/(3!2!)) = 10

Where 5 is the number of red marbles in the bag.

Therefore, the probability of drawing three red marbles is:

10/364 = 5/182

So the probability of drawing three red marbles out of the bag is 5/182 or approximately 0.0275.

To answer the question correctly, it is important to note that economic opportunities for women vary greatly within Western Europe, and it would be inaccurate to make a generalization for the entire region. However, according to the latest Global Gender Gap Report by the World Economic Forum, countries like Iceland, Norway, Finland, and Sweden are among the top-ranked countries globally for gender equality and economic opportunities for women.

These countries have implemented policies and practices that promote gender equality, including equal pay, flexible working arrangements, and parental leave, which have enabled women to participate more fully in the labor market. Other countries in Western Europe, such as the Netherlands, France, and Germany, have also made significant progress in promoting gender equality, although challenges remain in closing the gender gap in areas such as representation in leadership positions and access to finance.

A: Carbon absorbed by the hydrosphere through photosynthesis is equal to the carbon released to the atmosphere through respiration and decomposition.

What is carbon cycles?

The exchange of carbon dioxide between the atmosphere and oceans is better known as the natural carbon cycle.

This cycle takes place through both physical and biological processes. Specifically, marine plants and phytoplankton perform photosynthesis which efficiently ingests carbon dioxide from the atmosphere inadvertently cleansing it in the process.

Conversely, organismal respiration coupled with organic decay releases excess carbon into the air- undoing the previous work done by organic phototrophs. Nonetheless, a balance appears to exist within this hydrospheric cycle: intricately sustaining itself despite cyclical interruptions influenced by outside factors.

You roll a 6-sided die. What is P(not even)? Write your answer as a fraction or whole number.

Answers

Rolling a not-even number has a 0.5 percent, or half, chance of happening. When a dice is rolled, there is a 1/6 chance that each result will occur. There is just one probability outcome that is favorable. An outcome is a stand-alone occurrence.

A 6-sided die has three even numbers (2, 4, and 6) and three odd numbers (1, 3, and 5).

The probability of rolling an even number is 3/6 or 1/2 since there are three even numbers out of six possible outcomes.

To find the probability of rolling a not-even number, we need to subtract the probability of rolling an even number from 1 (the total probability).

So, P(not even) = 1 - P(even) = 1 - 1/2 = 1/2.

Therefore, the probability of rolling a not-even number is 1/2 or 0.5.

As temperature decreases, relative humidity increases if the amount of water vapor in the air remains the same.

How to explain the information

As temperature increases, the water vapor capacity of air also increases. This means that warmer air can hold more water vapor than cooler air. Conversely, as temperature decreases, the water vapor capacity of air decreases as well.

Relative humidity, on the other hand, is the amount of water vapor in the air compared to the maximum amount of water vapor that the air can hold at a particular temperature. As the temperature increases, the relative humidity decreases if the amount of water vapor in the air remains the same. This is because the air can hold more water vapor at higher temperatures, so the same amount of water vapor will be a smaller fraction of the maximum water vapor capacity.
