Answer:
Fossils refer to the remains of the past life like shells, bones, or other tough parts, and it may also comprise the proof of past life-like leaf impressions or footprints. A geologic time scale refers to the timeline, which demonstrates the past time of the Earth.
The planet in which we live is very old, and the study of the past of the Earth needs one to think about the times, which were millions or billions of years old. The geologic time scale is used by scientists to explain how the incidents took place on Earth.
The development of the geologic time scale was done after scientists witnessed certain modifications in the fossils that took place from the oldest to the newest sedimentary rocks. The phenomenon of relative dating was used to differentiate the past of the Earth in many parts of time when the same organism was there on Earth.
Answer:
A 0.4 g/cm³
Explanation:
The density of a substance, which is a cube in this case, can be calculated by using the formula:
Density = mass/volume
Where;
Density = g/cm³
Mass = grams
Volume = cm³
In this question, each side of the cube measures 3 cm. This means that the volume of the cube can be got by multiplying 3 × 3 × 3 = 27cm³. Hence, volume of the cube = 27cm³.
Mass of the cube = 12g
Density = 12/27
Density = 0.4444
Approximately, density = 0.4 g/cm³

The answer is; TRUE
When the saturated solution is allowed to cool slowly, the molecules in the solution have the time to displace impurities that try to attach to the growing lattice because they fit perfectly, geometrically then the impurities. This way the lattice grows larger.
If the solution is cooled fast, the impurities have little time to be displaced from the lattice hence the geometry of the crystal lattice is disturbed and the crystals are smaller and less pure.
