Answer the assignment questions using the World Geology map in this lesson and/or the earth's lithospheric plates map in the assignment document. You can also do an Internet keyword search for U.S. Geological Survey Plates of the Earth Map to find some really good images that can be used as a reference for this assignment.

1. Wegener formed the theory of continental drift in 1912. What prevented research of the ocean floor, paleomagnetism, and earthquakes at that time?

2. If many different observations can all be explained by the same theory, does that make the theory true? Does it make the theory more likely? Explain your answer.

3. What evidence is there to suggest that the Earth is composed of tectonic plates?

4. What evidence is there to suggest that tectonic plates move?

5. Select Topography and Major Plates on the World Geology map. Describe the topography at the boundaries between the following pairs of plates: South American and Nazca, Indian and Eurasian, and Pacific and North American.

6. Observe the border between the Indian plate and the Somali plate. Do you see the same landforms as at the boundary between the Indian plate and the Eurasian plate? Explain.

7. Select Earthquakes and Major Plates on the World Geology map and observe earthquake activity around the South American plate. Based on your observations, what can you conclude about lithospheric motion of the South American plate with the Nazca plate and the African plate? Explain your answer.

8. How certain do you feel that the theory of plate tectonics is correct? What evidence would you use to support your opinion?

All physical things with mass are drawn to the gravitational force, which may be thought of as an attracting force. It is the known natural force that is by far the weakest. The pairs in order from weakest to strongest gravitational force is B, A, C, D.

What is gravitational force ?

Any two mass-containing objects are attracted to one another by the gravitational pull. Because it consistently attempts to bring masses together rather than pushing them apart, the gravitational force is known as attractive. In reality, you and every other item in the cosmos are tugging on one another.

All objects with mass, including our Earth, really bend and twist spacetime, which is what causes gravity to pull you toward the earth.

The masses of the two objects and their separation from one another will determine how much gravitational pull there is between them. Each object's mass and gravitational force are inversely proportional.

Thus, The pairs in order from weakest to strongest gravitational force is B, A, C, D.

What happens to the volume and temperature of a liquid and gas when they are placed under pressure in a sealed container? Explain.

Answers

The pressure law states that for a constant volume of gas in a sealed container the temperature of the gas is directly proportional to its pressure. This can be easily understood by visualising the particles of gas in the container moving with a greater energy when the temperature is increased.

Hope this helped

The temperature an volume of liquids and gases are dependent upon the pressure of the substance. When liquid and gas particles are placed in a high pressure container then they change their medium from liquid to solid and from gas to liquid.

What is the effect of pressure on gas and liquids?

The pressure law states that for a given constant volume of gas in a sealed container the temperature of the gas in the container is directly proportional to the pressure of the gas. This can be easily understood through visualizing the particles of a gas in the container which is moving with a greater energy when the temperature is increased in the container.

Thus, when the pressure is applied on gas particles, it compresses to liquid and when the pressure is increased on liquid material, it becomes solid. The effect of pressure on solid is negligible as it does not change anything in solid. Thus, if the pressure is applied to a substance its state changes from Gas → Liquid → Solid.

Rotation of players should be done how?

A. Clockwise movement

B. Counter-Clockwise movement

C. You don't have to rotate positions

D. Zigzag movement

Answers

Answer:

Clockwise movement

Explanation:

Players rotate “clockwise” through each of these positions. Another way to remember it is the player in 1 serves first, the player in 2 serves next, the player in 3 serves third, and so on. The order of rotation is set at the beginning of the game and maintained throughout the game (excepting substitutions).
