Answer: IQUID WATER DUE TO LOW ATMOSPHERIC PRESSURE WHICH IS LESS THAN 1% OF THE EARTHS EXCEPT AT THE LOWEST ELEVATIONS FOR SHORT PERIODS. ( FOR FURTHER INFORMATION GO TO MARS - WIKIPEDIA https://en.m.wikipedia.org)
Explanation: MARS IS THE 4TH PLANET FROM THE SUN . IN MARS THE IRON OXIDE PREVALENT ON ITS SURFACE GIVES IT A REDDISSH APPEAREANCE THAT IS DISTINCTIVE AMONG THE ASTRONOMICAL BODIES VISIBLE TO THE NAKED EYE.
Answer:
D fossil record
Explanation:
Depending on what layer of earth the fossil was recorded then they could determine a rough date. Then they would use carbon dating to be more exact.
Answer: Normally, the invasive species can reproduce rapidly because their environment has no/lacks predators and pests.
Answer:
A. light penetration
Explanation:
Water clarity refers to how clear a water is, and it is a measure of how far/deep light can penetrate into such a water body. A water that is not clear is said to be TURBID. Several factors affect the clarity of a water body and they include;
- Phytoplankton, which refers to floating algae on the water body. An accumulated growth of phytoplankton can affect the penetration of light into the water, hence, making the water unclear.
- Suspended sediments can also block the penetration of light into the water, reducing water clarity.
- Nutrients in form of fertilizer or waste materials can also make water unclear.
Therefore, LIGHT PENETRATION DOES NOT IMPACT WATER CLARITY, rather it is dependent on water clarity.
