Define the difference between
hypothesis, theory ,and law

The hypothesis is the suggested explanation for a phenomenon while the theory is based on facts or tested explanation.

Explanation:

A hypothesis is a suggested explanation, an idea that is presented for argument so it can be tested to see if it is true. The hypothesis is made before any research has been done for it.

a theory is a proved or tested, unifying, well-substantiated, explanation for a set of verified, proven factors. It is a factual prediction, but a hypothesis is a reasoned explanation.

Thus, the hypothesis is the suggested explanation for a phenomenon while the theory is based on facts or tested explanation.

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.

i think the answer is a, hope this : )
