Why so earth scientists use 2 different ways of classifying earths layers ?

1 answer:

8 0

The Earth’s layers can be categorized mechanically or chemically. The chemical classification is more simple and includes the inner and outer core and the mantel which is divided into the upper and lower mantle. The crust is the surface. However, in the mechanical classification divides the lithosphere, the asthenosphere and the mesospheric. It is important to have the mechanical classification to understand the forces that move the tectonic plate.

Why is it cyclones are given female names?

Allisa [31]

I did some research, and I found this: "Since 1953, US started using female names. The practice came to an end in 1979 when the US Natural Weather Service and the World Meteorological Organisation developed a systematic way of naming cyclones in the beginning of the year, alternating male and female names, arranged in an alphabetical order."
Hope this helps you, and happy studying~!

Figure 1 shows how Earth’s surface looked 250 MYA. Today, it looks as shown in figure 2. Which processes are partially responsib

Xelga [282]

Weathering and erosion

Explanation:

Weathering and erosion are the processes that would be partially responsible for the change in the landmasses. Since the image shows movement of continents to their current positions, their surfaces would have been sculpted by the agents of denudation through its 250mya history.

Denudation is the gradual process of lowering and leveling of the earth surface by breaking and wearing away of such surfaces.
The agents of denudation are wind, running water, ice and waves.
Denudation is a constant process that the earth undergoes from time to time.

Arrange these steps in hurricane formation in order from first to last

yulyashka [42]

Answer:

From first to last, step wise is given below-

Tropical disturbance < Topical depression < Tropical storm < Wind speed above 74 miles per hour

Explanation:

In order to form a hurricane, at first, the disturbances occur in the tropical region, which is characterized by the occurrence of heavy storm activity over a large area extending 100 miles, that exist for about 24 hours.

Then, with the more favorable conditions, the disturbances alter into stronger storms that spin forming a low-pressure center, and this condition refers to the tropical depression. The required amount of humidity is present in both the upper and lower portion of the atmosphere.

The pressure within the center of the tropical depression eventually gets down, and the air flows inward, thereby forming more stronger winds. With more decreasing pressure, the wind speed drastically increases. Thus, the storm becomes stronger.

When the speed of the wind becomes 74 mph or exceeds, then this type of storm is called a hurricane.
