Scientists cite evidence that Earth's climate has been changing significantly over the past 50 years. They also argue that changes to Earth's orbital path are NOT the cause of these significant changes to the climate. Which statement provides the strongest evidence in support of the scientists' argument? a
Variations in Earth's orbital path are consistent with accepted laws of planetary motion.
b
Earth's orbital path does not affect the amount of solar energy that Earth receives.
c
Changes to Earth's orbital path occur in a cycle that repeats every 100,000 years.
d
Climate change cannot be demonstrated over a span of 50 years.

b. read the phase at the intersection of any given temperature and pressure.

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds

the principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to test the hypothesis, and development of a conclusion that confirms, rejects, or modifies the hypothesis.
