Charles goodyear was a scientist who was looking for ways to keep rubber from melting in the summer heat and becoming brittle in the winter cold. he discovered the solution by accident when someone left a sample of rubber and sulfur on the stove. was this a scientific discovery? a. yes. goodyear was a scientist, so his discovery was scientific. b. no. goodyear failed to develop a hypothesis about the method. c. no. goodyear did not follow the scientific method. d. yes. goodyear used observations and empirical evidence.

The correct answer will be option-D

Explanation:

The discovery of the solution which prevents the melting of the rubber and the brittleness during winter by Goodyear will be considered a scientific discovery.

This is due to the fact that any scientific discovery begins with making an observation on the basis of which further steps will be followed. The accidental research of the solution act as evidence to the scientific observation.

Thus, option-D is the correct answer.

the answer is c. altitude. hope this ! #brainiac

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
