How do algae blooms destroy aquatic life?

by giving off toxins that kill life

A harmful algal bloom (HAB) contains organisms (usually algae, hence the name) that can severely lower oxygen levels in natural waters, killing marine life.

What, besides temperature can make ocean water significantly denser

salinity

High salinity makes water denser. This is because there is more salt packed into the water. High temperature makes water less dense. As water gets warmer, its molecules spread out, so it becomes less dense.

Which area best describes a continental slope?

Continental slopes are regions of steeply sloping seafloor that lie between continental shelves and the deep ocean basins (Figure 2). Regional gradients are typically 2–5°, but locally slopes may be much steeper.
