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

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

Explanation:

In conclusion, tropical cyclones are powerful and dangerous weather events that can cause extensive damage to coastal regions. These storms are characterized by their strong winds, heavy rainfall, storm surge, and potential for tornadoes. It is important for individuals living in hurricane-prone areas to stay informed about storm developments and to take appropriate precautions to protect themselves and their property. Governments and emergency response organizations should also have disaster plans in place to ensure effective responses to tropical cyclones. With careful planning and preparation, communities can minimize the impact of these devastating storms and work towards rebuilding and recovery in their aftermath.

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.

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.

The measures of the angles in the triangle are:

X ≈ 48.6°; W = 41.4°

The triangle is a right triangle, so we will apply the Trigonometric ratios to solve for for one of the angles in the image given.

To find angle X, apply the sine ratio (SOH):

sin ∅ = opp/hyp

sin X = 6/8

X = sin^(-1)(6/8)

X ≈ 48.6°

All angles in a triangle is equal to 180 degrees when added together, therefore:

angle W = 180 - 90 - 48.6

Craton is the name of plate or subplate that is formed consist of central mass of continental lithosphere compeltely surrounded by a broad zone of oceanic lithosphere​

The craton is the name given to the plate or subplate that comprises the central mass of continental lithosphere which is completely surrounded by a broad zone of oceanic lithosphere. A craton is a stable and relatively immobile part of the Earth's crust that forms the core of a continent.

It is typically composed of ancient, thick, and stable continental crust that has not experienced significant tectonic activity for millions of years. Cratons are considered to be the most stable and rigid parts of the Earth's lithosphere, and they form the foundation of continents. The Precambrian shields, such as the Canadian Shield and the African Shield, are examples of cratons.

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

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

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

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.

As temperature increases, water vapor capacity of air increases

As temperature decreases, water vapor capacity of air decreases

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

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

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.
