Answers

Answer: High tides and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. ... When you're not in one of the bulges, you experience a low tide.

What is the affect of increasing the temperature of the water?
What happens when you add pollution to the water?
Can coral survive bleaching?
What is coral?

Answers

Answer:

Explanation:

Increasing temp in water makes it start to boil and evaporate into the atmosphere, in terms of climate change it makes it hard for many organisms to survive because they have to adapt quickly to the waters rapidly rising temperature. When you add pollution to water the water would become contaminated and not be able to support life or be fit for human consumption.

Coral cannot survive bleaching because it harms the coral to the point of its destruction.

Coral is an animal that can grow into big reefs that create large ecosystems for many organisms. They are in the ocean. The biggest coral reef is the great barrier reef in Australia.
