Which processes produced heat that contributed to the formation of Earth's different layers? Check all that apply.
collision of materials
compaction of materials
cooling of low-density metals
radioactive decay
sinking of high-density metals
Answer:
a, b and d
Explanation:
it was correct on edge
The processes which produce heat that contributed to the formation of Earth's different layers include the collision of materials, compaction of materials, and radioactive activity.
There are three different layers that make up the Earth which are the mantle, the crust and the core. They are made of solid rock which is usually granite and basalt.The radioactive decay of the elements that are in the Earth's crust releases heat energy. It should be noted that about fifty percent of the internal heat that comes from the Earth is through radioactive decay.In conclusion, the correct options are A, B and D.

Which is the best estimated pressure, represented in units of GPa, of the lower mantle? 110 GPa 220 GPa 305 GPa 360 GPa
The correct answer is A. 110GPa
Explanation:
Pressure refers to a force applied to a surface or object either by another object or factors such as the atmosphere. This is calculated considering the force applied and the area. Additionally, this factor can be measured using the unit gigapascals (GPa), which is more common in geography and related areas.
In this context, the lower mantle, which is the layer below the upper mantle has a pressure between 24GPa and 130GPa; and this is a high pressure if compared to the pressure in the surface. Thus, the estimated pressure in this zone is 110GPa because this is the only number that is between the range of pressure in this zone, while others show a higher pressure that is not found in this layer.
Answer:110 GPa

Ridges are basically small elevations and if you look at them from a flat surface, they might even look like small mountains. In reality they are only 700ft tall.
Valleys on the other hand are plains with not ridges or small mountains.
Therefore a ridge and valley region would consist of a series of elevations due to ridges and depressions due to the plain valleys.

What is the average of all data points in a data set? the mean the median the mode the range
Answer:
Mean
Explanation:
The arithmetic mean, also called the expected value or "average", as in your case is what the answer to your question should be.
The mean is the average of all data points in a data set. Hence, option A is correct.
What is meant by data points?The phrase “data point” generally corresponds to the singular form of data, or datum. It is the actual data obtained from a measurement or research, and in a statistical or analytical setting, it might be shown as a numerical data point, a statistical presentation, or a graph.
A collection of one or more measurements taken on a single member of the observational unit is referred to as an observation or data point.
In a study of the variables that influence the need for money using the individual as the unit of observation, the values of income, wealth, age of the individual, and the number of dependent would be examples of data points.
Thus, option A is correct.

In circle C shown below, a tangent has been drawn at point A. If m CBA 28 then explain why the measure of DAB must equal 62.
Answer:
The solution is shown below
Explanation:
From the image attached:
Line BC and line AC are the radii of the circle, therefore BC = AC.
Since BC = AC, the triangle ABC is an isosceles triangle with m∠CBA = m∠CAB = 28°
Also line ED is a tangent to circle C. From the circle theorems, a tangent to a circle is at right angle to the circle radius at point of contact. Since AC is a radii, ∠EAC = 90°
Therefore:
∠DAB + ∠EAC + m∠CAB = 180° (sum of angles on a straight line)
∠DAB = 180° - ∠EAC - m∠CAB
∠DAB = 180 - 90 - 28 = 62
∠DAB = 62°
