Answer:
C. A mass of air that is similar in temperature and humidity
Explanation:
An "air mass" refers to a big volume of air that is characterized by having similar or uniform "temperature" and "humidity"<em> (moisture).</em> They come from different source regions, thus they are classified accordingly.
The<em> "cold air masses"</em> come from the <u>polar area</u>s while the<em> "warm air masses"</em> come from the<u> tropical areas.</u> An air mass may cause a storm, for example, when an air mass moves to a new region and confronts another air mass there with a<em> different humidity and temperature</em>.
Stay indoors because earth quakes are dangerous and can split the ground into a hole or have so u can fall through there and injure yourself or die and natural disasters can occur so stay inside.
The layers will be denser as you move from the crust to the inner core.
The density are as the following:
crust (2.55 g/cm³)
upper mantle (3.9 g/cm³)
lower mantle (5 g/cm³)
outer core (11.05 g/cm³)
inner core (12.95 g/cm³)
Thus we can also see that the inner core is the densest layer.

The slope of segment CD is 7. The length of segment BC is √50 units and the figure is a square.
Explanation:
Part A
Slope of a segment is calculated as the ratio of rise over run
In this case, C (8,3) and D(7,-4)
The slope is m=Δy/Δx
Δy=-4-3=-7
Δx=7-8=-1
m= -7/-1 =7
The slope is positive as seen in the graph for segment CD
Part B
To find length of a segment, the formula to apply is:

Given that B(3,8) and C(8,3) then
x₁=3,x₂=8,y₁=8,y₂=3
substitute values in equation as;

The formula used to find length of a segment
Part C
The geometric figure is a Square.The proof is that the length of the segments is equal, √50 units
