They broke down mixtures by chemical means.
Answer:
Control
Explanation:
A scientific control represents an experimental condition that scientists set up to be able to properly interpret their results. A control is used to minimize variation in the results.
For example, in this experiment studying plant growth, it could have been particularly cloudy during the experiment, meaning sunlight might have been unusually low. If we didn't have the control, we wouldn't be able to tell if any changes in growth were a result of the cloudiness, or because of what we did during our experiment. Having a "normal" control allows us to compare our results within the experiment.
Answer:
A fast-moving wet slurry consisting of a mixture of water and volcaniclastic debris is termed a lahar
Explanation:
A lahar is a debris flow or mud-flow that consists of a mixture of volcanic material, rock particles and water, flowing typically along a river valley down from a volcano
Lahars can be either from either pyroclastic flows or heavy rainfall after a volcanic eruption
Lahars are hazardous as they can result in destruction, severe damage destroying buildings and some times entire small towns are wiped out. This is more so as they move silently and very fast down to the valleys
Answer- no :)
