Pollution Types, Moon Phases, Types of Mangroves, and Tides

4 types of pollutions

4 types of pollutions

Toxic, bacterial, sediment, and nutrient.

Toxic pollution

Description - Pollution caused by toxic chemicals and substances in the water.

Cause - Caused from improper disposal of chemicals, oil spills, etc.

Impacts - Can contaminate drinking water which causes cancer & disease

Bacterial pollution

Description - Pollution caused by human/animal waste being released into water resources.

Cause - Animal manure & untreated human waste.

Impact - Drinking water with this bacteria leads to dysentry and cholera.

Sediment pollution

Description - Pollution caused by erosion of soils into waterways during rain.

Causes - Logging, mining, and construction.

Impacts - destroys fish and wildlife habitat, clouds water, and blocks sunlight.

Nutrient pollution

Description - Pollution caused by excessive nutrients in water.

Causes - fertilizers, manure, human waste.

Impacts - Causes too much algae growth and leads to hypoxia & low oxygen conditions, killing fish and other animals.

3 types of mangroves

red, white, and black

Propagules

seeds from red mangroves that fall into the water to eventually grow.

Pneumataphores

White and black mangroves roots that get air.

Red mangrove

Submerged in the water and is red.

Has prop roots.

Thrives in coastal areas

White Mangroves

On land and not completely white.

Has pneumatophores.

Has chunky and waxy leaves.

Black mangrove

On land and not really black.

Has pneumatophores.

Has chunky and waxy leaves.

What do prop roots do

filter out 90% of salt. if they couldn’t, mangroves would die.

stabilize against currents, tides, and waves.

what do the chunky waxy leaves do

store and seal fresh water.

how are mangroves endangered?

their habitat is endangered.

We can hand grow mangroves once destroyed.

How do mangroves help climate change

roots store large amounts carbon.

Mangroves are:

guardians of the coast, and is a type of tree. they grow in intertidal regions.

high tide-

need salt

low tide -

need air

mangroves help

birds and fish have food, protects the coastlines, and more.

life cycle

propagules fall in water

grow

and become mangrove

phases of the moon

new moon, 1st quarter/half, full moon, 3rd quarter/half, and repeat.

full moon and new moon

make spring tides (strongest tides)

these tides produce highest and lowest tides.

half moons (1st and 3rd)

make neap tides (weakest tides)

these tides produce lower high tides and higher low tides.

waxes -

part of moon lit up appearing to be growing.

wanes -

part of moon appears to be shrinking

moons goes through

31 different phases and shapes, this is a cycle.

Solar eclipse -

earth (moon in the middle) sun

we see this placement monthly, but eclipes’ rarely.

if you see less than half a moon

its called a crescent moon

if you see more than half a moon

its called a gibbus moon

it takes the moon

29.5 days to complete the cycle.

moon and earth orbiting

do not sync

earth is orbiting a little faster

we occasionally see

2 full moons in a month

in between new moon and first quarter moon

we see a waxing crescent moon

in between first moon and full moon

we see a waxing gibbous moon

in between full moon and 3rd quarter moon

waning gibbous moon

in between the 3rd quarter moon and new moon

we see a waning crescent moon
