Answer:
(b) the night would be half as long
Explanation:
- As the earth, if rotated twice as fast than it does now and the sun stayed the same then the night would be as half as long as the rotation of the planet on its axis would be double to that of its and 12 hours of night would be as long as the speed of the axial rotation.
The atmospheric concentrations of CO2 during Earth's past have always been changing, sometimes slowly, sometimes abruptly. The changes continue to the present day, and will continue in the future. The reasons for the oscillations in the CO2 levels are numerous, but while in the past they have been exclusively from natural causes, in modern times it is also the humans that got involved in it. The Cretaceous period had 1000 ppm of CO2, while the Eocene had 560 ppm of CO2. In the present, the CO2 concentrations are 405 ppm, thus significantly lower than the Cretaceous and Eocene. What can be learned from these two periods though is that such high concentrations of CO2 result in much warmer global climates, with ice sheets lacking, and the temperatures being much more equalized across the latitudes. If the current trend continues, there is every chance that our planet will experience such changes in the near future.

Label C: indo-Australian plate
Explanation:
Answer:
C) around the base of Kauai, the oldest of the Hawaiian islands
Explanation:
- As the Hawaiian island is located n the southeastern parts of the seen islands spreading from the center and that reaches of the pacific plate margins and lies about the 56,00 km further to the southeast.
- Thus there is a sedimentary layer that is thickest at the older base of the munt Kauai has a greater amount of the from of biodiversity and fossil records. That can be found above the seafloor in the oceanic crust.
