The Thermal Characteristics of Water


ESSENTIAL QUESTIONS pg.156-159


1. Are heat and temperature the same or different? Why?
It is similar because heat determines the temperature, yet it is different because heat depends on the size and mass, while temperature change can be in ANY environment.

2. What is the heat capacity of water?
1gm of water requires 1 calorie of heat to raise its temperature by 1 degree celsius. This is referred to as Specific Heat

3. How is the heat capacity of water unique?
It can hold very large amounts of specific heat!

4. How does water's temperature affect its density?
The warmer the water is, the less dense. The colder the water is, the more dense.

The Chemistry of Water

1. The way water molecules are bonded, each hydrogen nucleus is bound to the central oxygen atom by a pair of e- that are shared between them.

2. The negative charge at the end of a molecule exerts attractions to e- showing the positive and negative charges of water and how they are distributed.

3. Due to surface tension, since the light molecules touch water averaging out to zero, there is no net force on the molecule.

4. I found that the fact that water has the ability to change from a liquid to a solid, also change colors from blue, to white and becoming harder, it's very unique about water and its density.

Sediment Cores and History

1. The author is Alyson Santoro and she is researching microbes in the nitrogen cycle.

2. The technique the researcher is using that is especially good at recovering delicate sediments is multicoring.

3. After the samples are loaded onto the ship, it is rushed to the cold an to measure oxygen concentration at different depths of the ocean

The name of the research vessel is Melville.

The Four Types of Marine Sediments

Four types of Marine Sediments and where they Derived From

  Lithogenous- Derived from land

Biogenous- derived from organisms

Hydrogenous or Authigenic- derived from water

Cosmogenous- derived from outer space

Economic Importance of Marine Sediments


1. What are some products that come from sediments?
* Building Materials for roads and structures
* Toothpaste
* Paint
* Swimming pool filters

2. How much of the world's energy comes from sediments?
* 1/3 of the worlds oil and gas (energy) comes from deposits within sediments of continental
margins

3. How important is sand gravel?
* Valued at more than $510M

Prezi Questions:
1. In what ways are sediments classified

2. List the four types of Marine sediments. Explain the origin of ea.

3. Where are sediments thickest? Are any areas of the ocean floor free of sediments

Island Arcs & Ocean Trenches

1. How and where do ocean trenches form? They form at convergent plate boundaries when one subducts between another.

2. Describe an island arc ? It is bands of islands shaped like An arc because of tectonic and volcanic behavior.

3. What is the deepest trench in the world? The Mariana Trench in the west pacific.

4. What trench does Japan lay next to? The Japan trench.

5. Why do island arcs ARC? (why aren't they a straight line?) It us the results from shapes of plate movement across the earth.

Abyssal Plains and Hills

1. Abyssal Plains- great stretches of flat surfaces across the ocean floor.

2. AP's are found between the edges of the continents and great underwater mountain ranges.

3. AP's consist of beds of volcanic rock covered in one thousand ft of thick "sediments."

4. AP's cover 1/3 of the earth's surface.
