The origin of Mars' moons is fairly controversial, and it's far from settled exactly where they came from.
One piece of evidence is that there are many dry river channels in the martian southern hemisphere, like those found on earth. This suggests that water made these channels, and that means that at some point there was water on mars. Water means that the temperature was above 320F for at least some part of the year, and that it was humid enough so that the water would not instantly evaporate.
scientists have tested rocks from the earth , from meteorites , from Mars and from the Moon they all had different metals in there and different ages as well ... so how cold they made all at once ?!!?
Edwin Hubble suggested the evidence of an expanding universe based on his observation of galaxies moving away from each other with increasing speed. This observation led to the development of the Big Bang theory, which proposes that the universe began as a single point and has been expanding ever since.
One piece of evidence supporting the occurrence of inflation is the increase in prices of goods and services over time. Another evidence is the decrease in the purchasing power of a currency, making it capable of buying fewer goods and services. Additionally, historical data showing a sustained upward trend in general price levels can also indicate inflation.
The visible spectrum contains two ends, infrared and ultraviolet. A shift of light towards the infrared end typically indicates the object is receding from the observer. Another explanation is that the object may be entering a deep gravity well, which would also stretch and distort light reflected or emitted from the object.
No. A meteorite is a piece of rock or metal that has fallen to the ground. Some asteroids, however, have moons.
The evidence that suggests that the prosperity of the 1920s was not on a firm foundation includes the fact that the Great Depression happened soon thereafter. The Installment Plan that allowed you to purchase goods without having to put much money down was also another suggesting piece of evidence.
A false piece of evidence is called "planting" or "fabricating" evidence. It is when someone intentionally places fake evidence to mislead investigators or jurors.

If the substance can conduct electricity in solution, create ions when dissolved in water, and form crystals with a regular repeating pattern, it suggests that the substance is an ionic compound. Additionally, if the substance has high melting and boiling points, this is another indication of ionic bonding.
the difference is that Primary evidence is took from that moment and secondary is a piece of evidence found from the past.

The fingerprint found at the crime scene is considered a key piece of evidence in the investigation.
It is a piece of physical evidence presented at trial.
