Melissa lives in a town called Greendale. She discovers that when she lights a match and holds it near her kitchen faucet, the l

ittle flame grows into a larger fire. Melissa is surprised because she thought the water would extinguish the flame rather than ignite it further. Her mother tells her that the water might be contaminated with dissolved methane, a primary component in natural gas. Melissa investigates the matter and finds that cases of methane contamination started shortly after a company began fracking for natural gas in the area. Based on this information, which three statements are plausible consequences of fracking in Greendale?
Fracking contributed to methane finding its way into the residential water supply.

Fracking is always safe to use in the proximity of Greendale's water supply.

Pressure from fracking forced methane to mix with Greendale's groundwater.

Fracking in Greendale produces more freshwater than it consumes.

If fracking can con

How are the troposphere and the stratosphere different
Likurg_2 [28]

Differences between the Troposphere and the Stratosphere:

The troposphere is the lowest level of the atmosphere, so it is in contact with the Earth’s surface. In contrast, the stratosphere is located above the troposphere, so it is not in contact with the Earth’s surface.  Humans live in the troposphere, not the stratosphere. People only spend time in the stratosphere is when they are traveling through it on an airplane, or flying through it while riding in a rocket.  The air density and air pressure are much lower in the stratosphere. In fact, stratospheric air is too thin for people to be able to survive without pressurized air to breathe.

Find the coordinates of the midpoint of HX
marta [7]

Answer:

M(29, -12)

Explanation:

Given:

H(4\frac{1}{2}, -3\frac{1}{4}), X(2\frac{3}{4}, -2\frac{3}{4})

Required:

Coordinates of the Midpoint of HX

Solution:

Midpoint (M) of HX, for H(4\frac{1}{2}, -3\frac{1}{4}), X(2\frac{3}{4}, -2\frac{3}{4}) is given as

M(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}).

Let H(4\frac{1}{2}, -3\frac{1}{4}) = (x_1, y_1)

X(2\frac{3}{4}, -2\frac{3}{4}) = (x_2, y_2)

Thus:

M(\frac{4\frac{1}{2} + 2\frac{3}{4}}{2}, \frac{-3\frac{1}{4} + (-2\frac{3}{4})}{2})

Convert to improper fractions

M(\frac{\frac{9}{2} + \frac{11}{4}}{2}, \frac{-\frac{13}{4} + (-\frac{11}{4})}{2})

M(\frac{\frac{18 + 11}{2}}{2}, \frac{\frac{-13 - 11}{4}}{2})

M(\frac{\frac{29}{2}}{2}, \frac{\frac{-24}{4}}{2})

M(\frac{29}{2}*2, \frac{-24}{4}*2

M(29, -12)

Which contour interval would be better on a topographic map of a mountainous area:
Elanso [62]

Answer:

30 meters

Explanation:

  • For a map of the mountainous area, the elevation has to be 5-100 meters. As the area is a mountain or a hilly upland area, it has a contour interval of 100 meters or more. For a relatively flat area it as to have a C.I of 10 meters or less.
