Part 5: Hot-spots and Absolute Movement Rates
The Gandalf Islands are analogous to the Hawaiian Islands on Earth. They form a linear chain that originated by the
migration of the plate over a mantle hot spot. Mantle hot spots have a fixed location.
All of the Gandalf islands are volcanic in origin but the easternmost and largest island, which is currently sitting over the
hot spot, is the only one with active volcanoes on it. The rocks on the westernmost island have been dated by radiometric
methods at 32 m.y..
16) Measure the distance between the centers of the westernmost and easternmost Gandalf islands and use this
information to calculate the absolute movement rate (in mm/y) of the Aragorn Ocean (and the Bilbo Continent,
which is connected to it). Show your equations and explain where you got each of your numbers.
Helpful Hint: As you are measuring absolute plate motion, pay no attention to the magnetic anomalies
when answering this question.

The South American countries that got their independence are mostly from the period between 1800 to 1821.

Independence refers to the condition of a person, nation, or country that exercises self-government over its territory.

After three countries of colonial rule, most south American countries got their independence between 1800 and 1821.

Therefore, B is the correct option.

Answer:

Explanation:

A)two ways that oceanic-oceanic convergent boundaries are different from oceanic-continental boundaries

1)The occurrence of Oceanic-oceanic convergence in the ocean are deep, when there is formation of trenches as a result of overlapping of one oceanic plate on another, then there will be scattering into small bits of the oceanic plate resulting in earthquake.

✓the nature as well as thickness of crust that exist in continental plates and oceanic plates: formation of oceanic plates is at divergent boundaries usually at ocean ridges. The Oceanic plates are thinner when compare with continental plates,

✓ Oceanic-continental convergence do cause mountain formation where there is overlapping of continental plate on

oceanic plate

B)How are they similar?

They are similar because convergence of each of them can catalyse formation of a volcano, also the descending of one slab on another is similar.

Answer:

The Moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the Moon and the side farthest from the Moon. These bulges of water are high tides. ... High tides and low tides are caused by the Moon.

Answer:

Plate Tectonics

Explanation:

Earthquake is cause as a result of the shift in plate tectonics which happens in the space of ten years or more i.e it is once or twice in a blue moon.

Answer:

Due to presence of mountains and hills.

Explanation:

The topography which extends east-west consists of mountains and hills which is the main reasons for their irregular shape and structure. I think that hiking across this terrain is very difficult for the tourists due to its irregularity and passing through this topography consumes a lot of time. Due to the presence of mountains and hills, the topography looks beautiful but irregular.

Rocks and minerals are all around us! They help us to develop new technologies and are used in our everyday lives. Our use of rocks and minerals includes as building material, cosmetics, cars, roads, and appliances. In order maintain a healthy lifestyle and strengthen the body, humans need to consume minerals daily. Rocks and minerals play a valuable role in natural systems such as providing habitat like the cliffs at Grand Canyon National Park where endangered condors nest, or provide soil nutrients in Redwood where the tallest trees in the world grow.

Rocks and minerals are important for learning about earth materials, structure, and systems. Studying these natural objects incorporates an understanding of earth science, chemistry, physics, and math. The learner can walk away with an understanding of crystal geometry, the ability to visualize 3-D objects, or knowing rates of crystallization.

Answer:

Plates at our planet's surface move due to the exceptional warmth in the Earth's center that causes liquid stone in the mantle layer to move. It moves in an example considered a convection cell that structures when warm material ascents, cools, and at last sink down. As the chilled material sinks off, it is warmed and rises once more.

Answer:

The oceanic crust is forced under the continental crust and into the mantle. Crompression causes mountains to form on the continental crust. Material in the mantle melts as volatiles seep out of the oceanic crust. The molten material rises to the surface, forming a continental volcanic arc.

1. They usually host three or more ecosystems where animals can’t live.

4. They usually host one ecosystem with a variety of plants

Explanation:

A mountain ecosystem has more than one ecosystem. This is mainly due to the diversity of climate that this environment promotes. Due to its proximity to the ocean, slope and elevation, the mountain ecosystem promotes different areas that create different ecosystems, some more humid and others drier.

In this environment there is usually a wide variety of plants, but not animals.

Answer: Rivers are channels of water which drain the land's surface. They erode, transport and deposit materials, creating steep valleys and wide floodplains. As river's cut into the landscape they expose bedrock, leading to further change through weathering and mass movement. breaks up the hillsides near the river's source.

Answer: 4°C/m

Explanation:

Temperature gradient = Difference in temperature/ Difference in height

Difference in temperature = 32 - 24

= 8°C

Difference in height = 2 meters

Temperature gradient = 8 / 2

= 4°C/m

Answer:

natural gas

Explanation:

Natural gas is the fossil fuel which can be stored underground due to the fact that, it is easily evaporated when exposed to the air. To prevent its loss due to exposure, there is need to store it below its normal temperature thereby liquefying it (making it to exist as a liquid rather than gas). Also, transportation through the pipelines helps in its protection rather than open transportation using trucks due to its high volatile nature.

Answer:

Greece started a democracy, and Rome started a republic. What political ideas came from ancient Greece and Rome? Balkan - Part of the Eastern Roman Empire :)

The political ideas come from ancient Greece and Rome are democracy, justice, and equality.

Democracy in ancient Greece served as one of the first forms of self-rule government in the ancient world. The system and ideas employed by the ancient Greeks had profound influences on how democracy developed, and its impact on the formation of the U.S. government.

The ancient Greeks were the first to create a democracy. The word “democracy” comes from two Greek words that mean people and rule. Democracy is the idea that the citizens of a country should take an active role in the government of their country and manage it directly or through elected representatives. In addition, it supports the idea that the people can replace their government through peaceful transfers of power rather than violent uprising or revolution.

Thus, a key part of democracy is that the people have a voice.
