Answer:
Why don't we have a complete fossil record of all life that's ever lived? Fossil formation requires a rare mix of physical and biological conditions. Fossils must be exposed at Earth's surface to have a chance of being found. Fossils can be destroyed when rocks erode, melt, or change composition.
Explanation:
For many reasons, the fossil record is not complete. Most organisms decomposed or were eaten by scavengers after death. Many species lacked hard parts, which are much more likely to fossilize. Some rocks and the fossils they contained have eroded and disappeared.

Answer:
Balanced
Explanation:
The image below is balanced because the forces are oppositely directed and have equal magnitudes.
- Based on newtons first law of motion "a body will remain at rest or continue with uniform motion unless if it is acted upon by an external force".
- The external force creates an unbalanced force resolution on a body.
- For this body, a force of 5N acts to the left
- A force of 5N acts to the right
When forces are directed this way;
Resultant = 5N - 5N = 0N
A resultant force of 0N shows a balanced body.
Answer:
3:The Pacific Ocean is the largest and deepest of the world ocean basins. Covering approximately 63 million square miles and containing more than half of the free water on Earth, the Pacific is by far the largest of the world's ocean basins. All of the world's continents could fit into the Pacific basin.Nov 2, 2019
4.The Arctic Ocean is the coldest ocean and has average temperatures of about 28 degrees Fahrenheit.
5: Although it might seem illogical, the Atlantic Ocean is warmer.
6:is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam. Challenger Deep is approximately 36,200 feet deep.

Answer:
Answer in Explanation
Explanation:
Before we proceed to explain the relation between the two, we need to understand what these terms are.
Acidification of the ocean simply refers to an increase in the acidic content of the ocean due to increased level of dissolved carbon iv oxide.
When we talk of climate change, we are talking about the overall and continual change of the atmospheric conditions of the Earth.
The reason why there is a climate change increase is because the atmosphere which is supposed to serve as a sink for green house gases is not serving this purpose and as such there is a retention of the green house gases such as carbon iv oxide within the sun-atmospheric level on the earth.
These green house gases such as carbon iv oxide which does not find a way out of the earth’s atmosphere will be retained in bodies within the earth crust serving as a sink for them. An example of this sink is the ocean which thus takes in the carbon iv oxide which when dissolved increases the acidic content of the ocean causing acidification
