Answer: The earthworm contracts and extends in its movement, but the nematode moves side by side.
Explanation:
NOTE: By mode of location, we mean the way it moves.
The skin of a nematode is very unusual in that it secretes a thick outer cuticle which is both hard and flexible. And this cuticle makes it sustain a side by side mode of location. The closest thing a roundworm has to a skeleton is its cuticle and it uses it as a support and balance point for movement. Long muscles lie just underneath the epidermis and are all aligned longitudinally along the inside of the body, so the nematode can only bend its body from side to side, not contract or extend itself.
Whereas the earthworm extends and contracts as its mode of location.
An earthworm moves by using its two different sets of muscles: circular muscles for looping around each segment, and the longitudinal muscles for running along the length of the body.
The contraction of the circular muscles make the earthworm stretch becoming longer and thinner. The earthworm uses its longitudinal muscles to contract and thus becomes shorter and wider or it bends from one side to the other, pulling the body forward in the process. The earthworm withdraws the front setae and uses its rear setae to anchor itself at the back. Then the earthworm uses its circular muscles to lengthen and push itself forward again.
Answer:
If the earth weren't tilted, it would rotate like that as it revolved around the sun, and we wouldn't have seasons—only areas that were colder (near the poles) and warmer (near the Equator). But the earth is tilted, and that's why the seasons happen.
Explanation:
Clay minerals can be weakened either when they absorb water (incorporate it into their mineral structures) or when they absorb water (bind it onto their crystal surfaces). This can destabilize a slope.
What can destabilize a slope?
Slope failure can be caused by a variety of events, usually a combination of several. For instance, poor construction on a steep slope may be followed by intense rainfall. Although in this instance excessive rain caused the incident, other variables also contributed to the slope becoming unstable.
What causes slopes to become destabilized?
This makes the soil heavier since water is denser than air. Slope instability can result from an increase in stress because weight is equal to force, which is equal to stress divided by area. The angle of repose can be altered by water (the slope angle which is the stable angle for the slope).

The correct question is
Clay minerals can be weakened either when they _______ water (incorporate it into their mineral structures) or when they _______ water (bind it onto their crystal surfaces). This can destabilize a slope.
The last option best shows a meteorite.
Meteorite definition: A meteorite is a solid piece of debris from an object, such as a comet, asteroid, or meteoroid, that originates in outer space and survives its passage through the atmosphere to reach the surface of a planet or moon.
