APES - ocean warming, acidification, forestry

Ocean warming is caused by…

increase in GHG’s in atmosphere

What is a result of ocean warming?

coral bleaching, the coral polyps become stressed and loose algae

List 3 ways ocean warming affects marine species:

1. loss of habitat

2. metabolic changes

3. reproductive changes

What is ocean acidification?

It’s when CO2 in the atmosphere dissolves in seawater, forms carbonic acid, and lowers the pH of the ocean. this lowered pH makes it harder for animals with shells made of calcium carbonate to form the shells they need and it causes coral bleaching.

When CO2 is released into the atmosphere, the oceans absorb it. What’s the result?

the pH of the ocean is lowered

How does ocean warming affect metabolism?

Animals living in the ocean depend on the oceans temperature to regulate their bodies. When the temperature is higher they undergo metabolic stress and denatures their enzymes making it hard to metabolize or reproduce.

Dissolved ________ is decreased when ___ increases.

oxygen, temperature

What is H2CO3?

Carbonic acid

List 2 anthropogenic harms to the ocean:

1. burning fossil fuels

2. deforestation

What is CaCO3?

calcium carbonate

What are shells made of?

Calcium carbonate, CaCO3

As carbonic acids increase, _____ ______ decreases.

calcium carbonate

What is an acid?

a solution with more H+ ions

Explain how it affects coral?

Acidification makes it difficult for coral to form shells because of the loss of calcium carbonate.

CO2 in atmosphere goes into the ocean and becomes?

H2CO3 and H+ ions
