Question

13. Both Earth's atmosphere and inner Earth have additional layers. Continue your investigationby going higher (if you chose the troposphere) or deeper (if you chose the upper crust). (4points: 2 points for the coordinates of the point, 2 points for the slope)The atmospheric layer above the troposphere is the stratosphere. The stratosphere extends to50 km above Earth's surface. The temperature at the top of the stratosphere is -15°C.

Answer 1

The stratosphere extends to 50 km above Earth's surface.

The temperature at the top of the stratosphere is -15 °C

If we graph height above Earth's surface (in km) on the x-axis and temperature (in °C) on the y-axis, the point (50, -15) would be on the graph.

The top of the troposphere is located at 20 km. At this point, the temperature is approximately -55 °C. Then, the point (20, -55) would be on the graph.

The slope of the line that passes through points (x1, y1) and (x2, y2) is computed as follows:

`m=(y_2-y_1)/(x_2-x_1)`

Replacing with points (50, -15) and (20, -55), we get:

`m=(-55-(-15))/(20-50)=(-40)/(-30)=(4)/(3)`

The slope is 4/3
