The cold water observed along the northern California coast in summer is mainly due to: upwelling .
- here Upwelling is a process in which deep, cold water rises toward the surface replaces warm water from the surface.
- Winds blowing across the ocean surface push water away. Water then rises up from beneath the surface to replace the water that was pushed away. This process is known as “upwelling.”
- Upwelling occurs in the open ocean and along coastlines. The reverse process, called “downwelling,” also occurs when wind causes surface water to build up along a coastline and the surface water eventually sinks toward the bottom.
- Water that rises to the surface as a result of upwelling is typically colder and is rich in nutrients. These nutrients “fertilize” surface waters, meaning that these surface waters often have high biological productivity. Therefore, good fishing grounds typically are found where upwelling is common.

Answer:
rocks that are pulled apart are under tension. rocks under tension lengthen or breaks apart. tension is the major type of stress at divergent plate boundaries. when forces are parallel but moving in opposite directions, the stress is called shear.
I'm pretty sure its Brazil and Venezuela,
<span>B. they needed access to bodies of water for trade
Water and aquatic access was necessary for water as well as access to trade.
