Natural systems are not made by humans. The solar system is not made by humans, so it’s considered a natural system.
The solar system is studied largely by observations using telescopes, helioscopes, and related equipment; the Earth itself yields many clues about the nature of the solar system and can be studied directly. For chemistry and properties of distant planets, probes can be sent to the surface (such have already been sent to surfaces of Mars, Venus, the Moon, Titan, etc.) or to perform fly-bys to take pictures, radar surface mapping through dense clouds, perform spectroscopic analyses, infrared imaging, etc.
list four possible clues to a chemical change
There are many clues to what ancient climates were like. One of them include what fossils are found in an area.
Three clues that a chemical change has occurred:Color changesa precipitate formsa gas forms
The evidence scientists have are fossil clues, plant clues, climate clues and rock clues. Fossil clues supported the idea because a certain fossil the Mesosaurus was found in two continents on opposite sides of the Earth and the only reason for that is if the lands came together at one time. Plant clues support the idea the same way fossil clues do, like the plant called a Glossopteris was found in different areas around the world. Climate clues support the idea because some of the fossils and plants from warmer climates were found in the Arctic. That explains why there are glaciers in tropical areas. Lastly rock clues support the idea because if the continents were once connected at one time, then the rocks that made up the continents should be in the same locations where they were joined.

Syntactic clues are aids to parsing. The amount of nondeterminism in parsers for pairs of homomorphically related semithue language systems is compared. If the parsers are without lookahead, the domain language system parser has no more nondeterminism than the codomain language system parser. The domain language system has at least as many clues. If the parsers have lookahead and the homomorphism is nondecreasing the same results hold. If the homomorphism is nonincreasing, an example shows the codomain language system may have the better clues.
