Exploring a New Place

Every location in the world is unique because of its people, culture, terrain, weather, and other features. If you had the opportunity to explore a new place, where would you go?

Write an essay that identifies one place that you have never visited before and why you would like to go there. Include details about the features of the location that interest you.

As you write, remember your essay will be scored based on how well you:

· develop a multi-paragraph response to the assigned topic that clearly communicates your controlling idea to the audience.

· support your controlling idea with meaningful examples, reasons, and information based upon your research and readings.

· organize your essay in a clear and logical manner, including an introduction, body, and conclusion.

· use well-structured sentences and language that are appropriate for your audience.

· edit your work to conform to the conventions of standard American English.

Assuming that the long term rate of displacement along the San Andreas Fault (about 3.5 cm/year) remains the same and that the l
Kisachek [45]

Answer:

17.71 years

Explanation:

  • As the crust of the San Andrea is continuously moving due to the tectonic activity and is the main manifest of the tectonic boundary of the North America and the pacific plate. This fault along with the pacific plate will move towards the Los angles and eastern San Francisco as it moves about 3.5 cm per year.
  • As  1 km equals to about 100 000 cm , then the distance of 620 km =  62, 000,000 cm  and 62,000,000 will be divided by 3.5 equal to  17. 71 years to collide with the eastern side.

7. Assume you are dealing with a vertical walled reservoir having a surface area of 650,000 mwith an inflow of 0.5 m/s. How many
finlep [7]

Answer:

So reservoir will take 455000 sec to raise 35 cm

Explanation:

We have given surface area of the reservoir = 650000 m^2

Rate of flow = 0.5 m/sec

Height through which reservoir is raise = 35 cm = 0.35 m

So volume \Delta V=surface\ area\times height=650000\times 0.35=227500m^3

We have to calculate the time

Time is given by t=\frac{\Delta V}{rate\ pf\ flow}=\frac{227500}{0.5}=455000sec

The inclusions were most likely broken off from their original rock layers
UkoKoshka [18]

The inclusions were most likely separated from their original rock layers during the magma intrusion.

An intrusion is a body of igneous (heated rock) rock that crystallized from molten magma. Gravity influences igneous rock placement by acting on density differences between magma and surrounding wall rocks (country or local rocks).

The inclusions were most likely separated from their original rock layers during the magma intrusion.

Why did scientists FIRST hypothesize that a meteorite impact caused the extinction at the K-Pg Boundary?
Stolb23 [73]

Answer:

They found evidence of an impact crater in Mexico

Explanation:

The K-Pg boundary is the boundary that separates two periods, but also two eras. The two periods that are separated by this boundary are the Cretaceous and the Tertiary, while the two eras are the Mesozoic and the Cenozoic. The boundary is marked by a mass extinction, and the scientists started to hypothesize as to why it happened. There were numerous different theories, but a clue in Mexico, or rather right next to the Yucatan Peninsula, shed new light on it. The scientists found an impact crater, formed either by a large asteroid or a comet. Such an impact would have easily caused sudden and drastic changes on the Earth, killing of the majority of the species. This impact released such a big amount of energy that it killed everything in the surrounding area in seconds. On top of that, it caused an extremely hot wave of air across the whole planet, killing many more organisms. It managed to trigger most of the volcanoes to erupt, as well as the earthquakes, causing also very large tsunamis. The sunlight got blocked for quite some time from all the aerosols in the atmosphere as well. This resulted in a mass extinction of the dominant species, like the dinosaurs, but it opened up the terrain for the evolution of the others, like the mammals.
