Answer:
The Carboniferous era had large deposits of coal matter in the soil. However there was absence of decomposers which gave rise to increased accumulation of organic matter in the soil.
Decomposers make use of oxygen to breathe in the soil due to their existence as animals and not plants. They inhale oxygen and give out Carbon dioxide.
Absence of these decomposers mean increased level of oxygen due to its non usage and reduction in CO2 which is the end product of respiration for the decomposers.
The correct answer for this question is this one:
<span>The impact on the christmas island crab population of a very dry season is that their spawning will be lesser than compared to the previous years. The effect of the climate change has a greater one with the crab population.</span>
Hope this helps answer your question and have a nice day ahead.
Temperature and Pressure differences. As air gets hotter it expands and therefore loses density, rising up. Cooler air then flows to fill the area the hot air left behind.
Wherever you observe the expansion from the universe from, you will appear to be at the centre of the expansion. thats what I would say.
Answer:
Space junk can damage satellites and can be lethal to astronauts.
Explanation:
Most of the object considered space waste are very small and travel around the Earth at high speed. Because of this, they can be dangerous for launch vehicles, satellites, the International Space Station and any manned mission should they collide with a spaceship.
The plan proposed by Roosegaarde to reduce space junk starts with a public awareness program that helps inform the public about the reality of space junk.
The eventual plan to end the space waste problem is to upcycle the debris floating around the planet. I think with the use of new technologies it will certainly be possible to eventually eliminate space waste.
