Friday Aquatic biome pollution

Today: January 17

• Turn In today:

  • SEV1d&equiz

• Agenda:

  • Eutriphication

  • Quizizz on Ocean Acidification

  • Review the Frayer Model assignment

  • Check missing or check understanding of assignments

• Homework:

  • C.E.R. and Frayer model assignments-How did you do?

CAMERA POLICY

Teachers will send a private message then verbal warning if a student’s camera is
not on. Continued non-camera use will result in moving up the discipline ladder.

First offense: Teacher conferences with student and documents in IC.

Second offense: Teacher conferences with student, contacts LC and documents in
IC.

Third offense: Teacher conferences with student, contacts LC, sends over to
academic coach for support and documents in IC.

Fourth offense: Academic coach submits discipline referral to discipline AP

Please make sure to turn your camera on at the beginning of each class.

You can set it to private (only teacher sees) or public (everyone sees).

Learning Target

I can explain how people affect water, and aquatic
organisms.

I can identify the difference between eutriphication and ocean acidification.

The terms for sev1e are included with the cheese maze assignment

​

Vocabulary for sev1e

Water Pollution

Foreign substances make their way into the water ways.

​

​What is it?

• Top pollutant in NC is sediment.

Two Types of Pollution

• Comes from multiple sources.

• Cannot identify, and therefore cannot lay singular blame

• Can directly identify the exact source of pollution.

• singular

​Point Pollution

​Non-Point Pollution

Multiple Choice

The multiple sites of pollution along the Mississippi river is an example of

• point pollution

• non point pollution

...we use fertilizer for those crops.


However, some of that is transported into waterways through runoff.

​

​When we grow crops...

This process is called eutrophication.

When there are too many nutrients like nitrates and phosphates in a water body.

​

​Eutrophication:

Multiple Choice

What does eutrophication result in?

• Excessive growth of algae and other aquatic plants, depletion of oxygen in water bodies, and disruption of the ecosystem.
• Reduced growth of algae and other aquatic plants, increase of oxygen in water bodies, and improvement of the ecosystem.
• No effect on the growth of algae and other aquatic plants, maintenance of oxygen levels in water bodies, and preservation of the ecosystem.
• Decreased growth of algae and other aquatic plants, increase of oxygen in water bodies, and enhancement of the ecosystem.

There are several types of pollutants.

Understanding Ocean

Acidification

Climate Chemistry

What is ocean acidification?

●Ocean acidification is a phenomenon caused by the absorption of
carbon dioxide (CO2) from the atmosphere into the surface waters
of the ocean.

●This process leads to changes in the chemical composition of
seawater, resulting in a decrease in pH and alterations in carbonate
chemistry.

●Understanding the chemical processes underlying ocean acidification is
crucial for comprehending its impacts on marine ecosystems and
biodiversity.

Carbon Dioxide (CO2) Dissolution

●CO2 from the atmosphere dissolves into ocean waters.

Carbonic Acid Formation

●CO2 reacts with water to
form carbonic acid (H2CO3).

●CO2 + H2O ⇌ H2CO3

a.Note: Reversible process
with equilibrium arrows.

Hydrogen Ion (H+) Release and
Bicarbonate Formation

●Carbonic acid (H2CO3)
dissociates into hydrogen
ions (H+) and bicarbonate
ions (HCO3-).

pH Change

●Increased dissolved
CO2 leads to carbonic
acid formation and
decreased seawater
pH.

Impact on Calcium Carbonate Structures

●Decrease in
carbonate ions
affects calcifying
organisms' ability to
form calcium
carbonate structures.

Multiple Select

What does pH measure (hint: there are two correct answers)?

• The acidity of a solution

• The amount of water in a solution

• How reactive a solution is

• How many extra hydrogen ions there are in a solution

​​Characteristics of biome

​Relating to stationary bodies of water, such as ponds and lakes, where water is not flowing.
