What are the reasons that the Earth heats up unevenly? Check all that apply. * the amount of energy coming from the Sun changes
Dafna1 [17]

Answer:

the Earth is tilted on its axis

the Earth is a sphere

different materials on Earth's surface absorb heat at different rates

Explanation:

The heating and cooling rates of land and water differ. This effects the heating of the earth according to these substances. Since the planet Earth is spherical in shape, the equator heats up more as compared to that of the polar regions. The differences in the seasons is because of the axis on which the Earth is tilted. Because of rotation, the heating and cooling of the Earth's surface differ. These are the reasons that are the reason for the uneven heating of the sun.

Lydia graphed δlmn at the coordinates l (0, 0), m (2, 2), and n (2, −1). She thinks δlmn is a right triangle. Is lydia's asserti
nadya68 [22]

No product results in -1, hence δlmn is NOT a right triangle showing that  lydia's assertion is incorrect

<h3>Perpendicular lines</h3>

In order to determine whether triangle lmn  is right-angled, we need to determine the slope of lm, ln, and mn first as shown:

For the slope of lm:

m_{lm} = \frac{2-0}{2-0}\\ m_{lm} =2/2\\m_{lm} =1

For the slope of ln:

m_{ln} = \frac{-1-0}{2-0}\\m_{ln} =-1/2\\

For the slope of mn:

m_{mn} = \frac{-1-2}{2-2}\\m_{ln} =-3/0 = \infty\\

  • If any of the two lines is perpendicular, hence the triangle lmn is right-angled.

  • To check, we will take the product of the slopes and see if it is equivalent to -1.

Product of slope lm and ln

m_{lm}\times m_{ln} = 1 \times -1/2\\m_{lm}\times m_{ln} = -1/2

Since no product results in -1, hence δlmn is NOT a right triangle showing that  Lydia's assertion is incorrect
