A certain sample of limestone formed when shells from organisms were buried under layers of sediment and experienced pressure. A student classifies the sample as clastic sedimentary rock. What is one problem with this classification
Answer:
The problem with this classification is clastic sedimentary rocks are not formed with organic elements, that is, they do not form with the remains of organisms, such as shells, for example
Explanation:
The student made an incorrect classification. This is because he classified a rock formed from shells as clastic sedimentary rock.
Shells are organic materials, as they are the remains of living organisms. Organic material is not capable of forming clastic sedimentary rocks, as these rocks are formed only by sediments. Remains of organisms, manage to form a type of rock called organic rock.

Horizontal variations in air pressure cause a force which makes the wind blow. These pressure variations are caused by a. warm temperatures in the stratosphere b. non-circular shape of Earth c. uneven heating of the Earth's surface d. greenhouse effect e. Earth's rotation
Answer:
The pressure gradient causes the air to move horizontally, forcing the air directly from a region of high pressure to a region of low pressure. The Coriolis force, however, deflects the direction of the flow of the air (to the right in the Northern Hemisphere) and causes the air to flow parallel to the isobars.

Natural Disaster Risk Assessment
CGC1D - Geography of Canada
Unit 2 Performance Task
Description:
Unit 2 focuses on the interconnection between all elements of physical geography including geology, climate, soil, vegetation, as well as a human activity, across the landscape. This performance task brings all topics of the unit together by researching the causes, effects, prevention, and importance that a natural disaster can have on the people impacted.
You will:
Choose a Canadian town/city that you think is at risk of at least one natural hazard/disaster.
Explain and prove why the city is at risk. The characteristics of the geology, climate, vegetation, and human activity around the city will help in your explanation. An example for geology: “San Francisco is at risk for an earthquake because it is located along a transform plate boundary between the Pacific and North American plates. When the plates slip past each other, large earthquakes are possible.” Use the attached organizer to layout ALL your research.
Present this information in an effective way (poster, Prezi, powerpoint, pamphlet, concise report etc.).
Include pictures, maps, or graphs in a meaningful and relevant way. Consider including risk maps/graphs, pictures of previous disasters, etc.).
Checklist/ Look Fors
I have provided a brief overview of the town's spatial significance. Geographic location (map), landform and climate region, population, and other helpful information related to risk assessment.
I have provided an explanation of how the natural hazard occurs.
I have provided a discussion of interrelationships and patterns/trends found between the landform/geology, climate, vegetation, and human activity. I have explained how these relationships increase or decrease the level of risk with my chosen city.
I have provided an outline of the strategies that are being used around the world to limit the impact of a natural hazard from various geographic perspectives.
I have compared the available strategies to the ones actually used by the city to determine if they are truly prepared for a disaster.
I have explained the social, environmental, political, and economic impacts that a hazard would have on my city.
The mark you receive will reflect how well you follow the guidelines stated above. See rubric for a detailed mark breakdown.
GOOD LUCK!
What continent was part of rodinia and later made up North American Continent?
Answer:
Rodinia was a Neoproterozoic supercontinent that assembled 1.1–0.9 billion years ago and broke up 750–633 million years ago.
Explanation:
Valentine & Moores 1970 were probably the first to recognise a Precambrian supercontinent, which they named 'Pangaea I'.
Information:In geology, a supercontinent is the assembly of most or all of Earth's continental blocks or cratons to form a single large landmass. However, some earth scientists use a different definition, "a grouping of formerly dispersed continents", which leaves room for interpretation and is easier to apply to Precambrian times. although at least about 75% of the continental crust then in existence has been proposed as a limit to separate supercontinents from other groupings
Tips:Neoproterozoic supercontinent
Explain different ways of determining latitude
Answer:
Latitude measures how far a point is north or south of the equator. the earth is round, distance from the equator is measured in angular degrees with the equator being 0 degrees and the northernmost point ..the North Pole -- being at 90 degrees.
A few ways of determining latitude are,
by comparing a person's position on Earth, by taking into consideration other geographical factors. Observing the position of the Sun. What is latitude?A latitude refers to as the unit of measurement, generally used to determine the position of a geographical region compared to the North Pole and the South Pole.
One can determine the latitude of any given region either by comparing their positions with the position of the North Pole. Additionally, the position of the Sun can also be compared with geographical position of any given region to determine the latitude.
Hence, the significance of latitude is aforementioned.

why did the united states of America eatablish a long term military presence in west germany in world war 2
The United States and other western nations occupied Western Germany in an effort to prevent the nation from rising to military power once again, like they did prior to WWII.
The plan was proposed by Joseph Stalin, arguing that if Germany rose to power a second time (like they had with the rise of Hitler between WWI & WWII), it would threaten European and international peacetime once again. The Allies agreed that they each would occupy a specific zone in the nation and administer the country until it could be reunified.
This kept Germany as a whole weak, and dependent on each occupying force for goods, which was part of the plan. By 1948, the Allies had begun unifying their sectors to help rebuild the nation, and the occupation ended around 1952, only to lead to the division of West and East Germany, and the rise of the Cold War.

Describe the different tectonic provinces of the Southern Appalachians, including the different rocks found within them, where they originated, and how they were affected by tectonic collision. Also identify younger examples of these provinces in the Western U.S.
Answer:
There are several tectonic provinces collectively called as crystalline providences.
Explanation:
The geology of Appalachians consists of Blue Ridge, Piedmont, Adirondack, and the New England providences. They are known as Crystalline provinces. The sinking of the oceans continued about 270 million year ago due to which a huge mass of rocks was pushed westwards along the margins of North America and piled up to form the mountains. The Sierra Nevada is the youngest mountain range on the west coast of the United States.Geography Lesson 1. Resources.

The diagram below shows undisturbed fossils in sedimentary rocks in two different locations. (2 points)
The picture shows two layers of rocks. In location 1, the top layer has fossils of leaves, the middle layer has fossils of fish, and the bottom layer has fossils of sea shells. In location 2, the top layer has fossils of sea shells; the middle layer has fossils of fish, and the bottom layer has fossils of leaves.
Which of these conclusions is most likely correct about the locations?
A. Both the locations have dense forests.
B. Both the locations are submerged under water.
C. Location 1 is a forest at present and Location 2 was a forest in the past.
D. Location 2 is a forest at present and Location 1 was a forest in the past.
Answer:
B. Both the locations are submerged under water.
Explanation:
Location 1 is a forest at present and Location 2 was a forest in the past of these conclusions are most likely correct about the locations. The correct option is C.
What are fossils How do fossils form layer by layer?When an organism dies and is buried for various causes, fossils typically form. The bodies or remnants of the organisms are then covered in layers of dirt, lava, ash, or sand. Due to various variables, such as pressure, these layers harden over time.
Location 1 had sea creatures living in its bottom layer, which indicates that it was once underwater. The middle layer has fossils of fish, which further supports the idea that it was submerged underwater. The top layer, which has fossils of leaves, suggests that it was a forest in the past and is above water level now.
Location 2 has sea shells in its top layer, suggesting that it was underwater in the past. The middle layer has fossils of fish, which further supports the idea that it was submerged underwater. The bottom layer, which has fossils of leaves, suggests that it was a forest in the past and is above water level now.
Thus, the ideal selection is option C.
