Gravels are the largest particles formed from the breakdown of rocks.
Hope this helps!
Im assuming it’s « Economic success brought political problems » because both economic and political collapses both occurred in Africa.
Answer:
The correct option is:
1) It was warmer than it is today
Explanation:
Caboniferous period lasted from around 360 to 300 million years ago. The term Carboniferous means rich deposits of coal. The deposits of coals occured in different region of Europe, Asia and Africa, including South China. In the start of the period, the average temperate was 20°C° which was dropped to 12° in the middle of the period. This cooling and drying resulted in Carboniferous rainforest. Hence, the temperature was warmer than it is today.

Explanation:
Answer:
C. temperature and salinity
Explanation:
The circulation of the water in the oceans is driven by the temperature and the salinity. It is a relatively simple principle that creates the movement of the water and creates the ocean currents.
The cold water is denser, so it sinks deeper. The cold water has lower salinity as well, as the evaporation in the higher latitudes is lower. It moves toward the lower latitudes in the form of deepwater currents, or better said it is moving toward areas with less dense water and pushes the water with smaller density. As this water gets to areas that are warmer it starts to warm up. Becoming warmer and warmer makes it less dense, the salinity constantly increasing because of the evaporation, so it is pushed up toward the surface.
Once it reaches the surface, the water is becoming even warmer and less dense, so in the form of surface currents it starts to move toward the higher latitudes. This continues to happen constantly, with periodic changes in the patterns of the currents, which depends a lot on the global climate and the position of the continental masses.
