marine sediments

Products that come from sediments are building materials for roads and structures, toothpaste, paints and swimming pool filters.

1/3 of the worlds oil and gas comes from sediments

Sand and gravel are valued at 510 million. Thats 1% of world needs

Sediments are classified as Clastic, biochemical, or chemical

The four types of marine sediments are lithogenous, biogenous, cosmogenous, and hydrogeneous.
They are ordered by origin of particles, grain size, and when they are deposited.

Sediments are the thickest closest to eroding land

abyssal plains

• Abyssal plains are underwater plain on the deep ocean floor
• They are usually found at depths between 3000m and 6000m; lying generally between the foor of a continental rise and mid-ocean ridge
• They are vast flat, sediment covered areas of ocean floor
•They cover more than 50% of earths surface

careers in studying oceans

1) Deep-Sea Biologist- investigator and studies deep sea corals. Any education level accepted for the job.

2) Geophysicist- someone who studies the Earth using gravity, magnetic, and seismic methods.

3) Microbiologist - investigates growth of bacteria, algae, and fungi.

4) Deep-Sea Ecologist - study hydrothermal vents and cold seeps deeps in the sea

I would like to be a deep sea ecologist because there are many things undiscovered down there and i would like to discover new things

adaptation of sea caves

-Typical adaptations for these sea cave creatures are:

• Their eyes are small or they have none
• They have sensors that don't depend on light for finding food and predators
• They have no skin color

-Oxygen is not plentiful in caves because there is no photosynthesis and very limited water circulation. The way they deal with the of oxygen is:

• They move slowly
• They have sensory body parts that don't require light
• They have low metabolic rates

-These adaptations occurring are completely random, so whether it provides an advantage to these creatures or not is by chance also

hypothermal vents

1. What exactly was described as "the biggest biological discovery on Earth?"
2. Where in the oceans was the discovery made?
3. What was “interesting” about Tube Worms?
4. How are species able to survive without sunlight? (What’s the process, if it’s not photosynthesis)
5. Where on Earth are hydrothermal vents located?
6. Describe the theory of how life on Earth may have began at hydrothermal vents?

Answers:

1. The HydroThermal Vents
2. Pacific oceans
3. Chemosynthesis
4. They bled human like blood
5. All over earth
6. Chemosynthesis- the process by which certain microbes create energy by mediating chemical reactions.
