The physical state that best describes the scientist's sample is solid (option C).
<h3>What are the states of matter?</h3>
Matter refers to any substance that has mass and occupies space. The states of matter are as follows;
- Solids; a substance in the fundamental state of matter that retains its size and shape without need of a container.
- Gases; a matter in a state intermediate between liquid and plasma that can be contained only if it is fully surrounded by a solid
- Liquids; substance that is flowing such as water; Liquids readily change their relative position, and which therefore retains no definite shape, except that determined by the containing receptacle.
According to this question, a scientist observed a sample of an unknown material to have molecules that are packed closely together and have fixed positions in space relative to each other. It has resistance to deformation and change of volume.
This description best fits the solid state of matter.

Answer:
Man-made disasters can include hazardous material spills, fires, groundwater contamination, transportation accidents, structure failures, mining accidents, explosions and acts of terrorism. There are actions that we can take to prepare to react appropriately to these events.

Answer:
Fossils, the shape of continents, the mid-ocean ridge system, sea floor sediment deposits, and the magnetism of rocks.
Explanation:
Fossils, the continent's shape, the mid-ocean ridge system, sea floor sediment deposits, and the magnetism of rocks on the sea floor are the evidences that support the theory of plate tectonics in the area. Fossils provides information to us when and where plants and animals once existed. Due to diverging plates, some life became isolated, and evolved into new species. Continental ‘fit’ through coastline matching. Some division of continents look as though they should fit together, e.g. South America and Africa.
