1. Fossils on continents that are now separated by ________ support the theory of continental drift.
2. Continents closer to the equator have warmer climates, yet fossils of ______________ have been found on islands near the North Pole. This supports the idea that islands drifted from the equator.
3. Coalfields in ____________ match those found in North America, supporting the theory of continental drift.
Answer:
Oceans, tropical species, europe
Explanation:
The continental drift theory put forward by the Alfred Wegner stare that the continental land got separate by the drifting of the plates that the oceans mas as they were close together in the form of a supercontinent, and are now separated by the large ocean bodies like that of the Jigsaw fit. The tropical species that were found in the equatorial belt s are now found in the island that is near to the place the dominance of the movement of the tectonic forces and the flight to poles explained in his theory. The coalfields that found in North America are similar to that of the European landmass that got separated and drifts away. Thus the S shape of the atlantic oceans is characteristic of this.Fossils on continents that are now separated by oceans support the theory of continental drift.
Continents closer to the equator have warmer climates, yet fossils of tropical species have been found on islands near the North Pole.
Coalfields in Europe match those found in North America, supporting the theory of continental drift.
What does Continental Drift show ?The theory of continental drift states that the continents were once joined together in a single landmass, called Pangaea. Over time, Pangaea broke apart and the continents drifted to their current positions.
The fossils of tropical plants and animals on islands near the North Pole provide evidence that these islands were once located closer to the equator. This is because these plants and animals could not have survived in the colder climate of the North Pole.

You have just bought your dream home along a coastline, but you notice that the beach in front of your new house is slowly disappearing. You decide to solve this by building a groin. Winds blow predominantly from east to west, so where do you place your groin? Group of answer choices
Answer:
The groin should be built perpendicular to the shore, and to the west of your house.
Explanation:
The groin will prevent beach erosion over time. And will help to stabilize the beach, if built correctly.
The winds will speed up the longshore drift process, and that is why the groin must be built to the west, to trap the sand and sediments before its washed away.
A beach groin is expected to last for about 40 to 50 years, so the problem would be solved for at least your entire generation.

Answer:
Accretionary prism
Explanation:
An accretionary prism or accretionary wedge is a mass of sedimentary material that is scraped off the descending slab at the boundary of a convergent plate
The sediments are pushed into thick vertical piles, where the pressure expels water from the sediments and converts them into rocks.
Two, small, poorly drained lakes lie close to each other in a northern forest. The basins of both lakes are composed of the same geologic substratum. One lake is surrounded by a dense Sphagnum mat; the other is not. Compared to the pond with Sphagnum, the pond lacking the moss mat should have:
A) lower numbers of bacteria.
B) less-acidic water.
C) reduced oxygen content.
D) reduced rates of decomposition.
Answer:
The correct answer is C)
Explanation: The lake with no Sphagnum mat has less disolved oxygen. The moss is a plant which generates and liberates oxygen as part of its metabolism. The oxygen disolves into the whater of the lake which has this Sphagnum mat, giving it a higher concentration of disolved oxygen than the other one.
What was the first ocean the caspian sea lost connection with
Answer:
The Pacific ocean.
Explanation:
The Caspian sea is actually a lake, a remnant of an ancient ocean during the mesozoic, the Tethys Sea. This served as a connection between Pacific and Atlantic oceans. Later on, as the continental platforms changed locations, it lost contact with the pacific ocean at first, then with the atlantic, and it became an isolated water body.
El Niño Choose one:
A. involves eastward-flowing warm surface currents that suppress the upwelling of nutrient-rich cold water along the coast of South America.
B. occurs when low pressure moves westward away from South America.
C. is regulated by air pressure cells shifting back and forth across the Atlantic.
D. can cause temporary climate changes on a 14-year cycle.
El Niño involves disrupting the usual upwelling of cold, nutrient-rich water along the South American coast due to eastward-flowing warm surface currents. Therefore, option A is correct.
El Niño is a climatic phenomenon akin to nature's intricate tango, where normally cold, nutrient-rich oceanic waters off South America succumb to the allure of warm, eastward-flowing currents.
This rhythmic disruption leads to atmospheric intricacies, triggering widespread shifts in weather patterns worldwide. Characterized by altered ocean temperatures and atmospheric pressures, El Niño orchestrates a symphony of climatic anomalies, affecting everything from torrential rains to parched landscapes.
Its far-reaching impact illustrates Earth's interconnected climatic dance, offering a vivid reminder of nature's delicate equilibrium and the profound influence oceans wield over our planet's meteorological performance.

Final answer:
El Niño involves the eastward movement of warm water across the Pacific, reducing the upwelling of cold, nutrient-rich water and affecting global weather patterns.
Explanation:
The phenomenon known as El Niño is characterized by the eastward flow of warm surface currents in the Pacific Ocean toward South America. This disrupts the normal upwelling of nutrient-rich cold water along the coast, which has various ecological and climatic consequences. During an El Niño-Southern Oscillation event, the trade winds weaken or even reverse, pushing the warm water eastward, which inhibits the normal upwelling process. This can lead to a dramatic drop in marine productivity due to the lack of nutrients reaching the ocean surface, which impacts fish populations and other marine life. El Niño events also influence global weather patterns, causing heavier rains and drought in different regions across the world.
Near the shore, waves of transition begin to "feel bottom" and, as a result, the orbits of the water molecules in the wave become more __________. This process eventually causes __________ to form.
a. elliptical; swells
b. circular; breakers
c. circular; swells
d. elliptical; breakers
Near the shore, waves of transition begin to "feel bottom" and, as a result, the orbits of the water molecules in the wave become more elliptical. This process eventually causes breakers to form. Thus the correct option is D.
What are waves of transition?Waves that travel in liquid at depths larger than a twentieth of the wavelength but less than half the length are known as transitional waves. It denotes a more condensed set of Transition-related tasks that must be carried out or done.
The waves are refracted as they begin to "feel bottom," change in wavelength, and speed as they travel diagonally toward the shore. As where the wave crest hits shallow water, the wave bends in this direction.
Therefore, option D is elliptical; breakers are appropriate.

Which of the following factors could explain a gradual warming trend in a planet's climate?
A) a decreasing albedo.
B) a decrease in the amount of greenhouse gases.
C) a decrease in the brightness of the Sun.
D) a major volcanic eruption that increases the albedo of the planet by making clouds.
E) none of the above.
Answer: I think the correct answer is E) none of the above.
Explanation:
A gradual warming trend in a planet's climate can be explained by a decreasing albedo, which means the planet is absorbing more solar radiation due to a reduction in surfaces that can reflect sunlight.
The question asks which among the given options could explain a gradual warming trend in a planet's climate. The correct answer is A) a decreasing albedo. Albedo refers to a surface's ability to reflect sunlight. A decrease in albedo means that a planet is absorbing more solar radiation, leading to a warming trend. This can occur through natural changes such as the melting of ice caps or human activities like urbanization that replace reflective surfaces with darker, heat-absorbing materials. Unlike the cooling effects of aerosols from volcanic eruptions, as mentioned in option A, a decreasing albedo contributes to warming. In contrast, a decrease in greenhouse gases or the brightness of the Sun would lead to cooling, not warming.

Answer:a.The movement of people between regions promotes the spread of culture.
Explanation: Possibilism is the idea that thought the physical environment can affect human actions, people have the ability to adapt to their environment.
Possibilism is a concept in geography and the statement 'The movement of people between regions promotes the spread of culture' is not an example of possibilism; rather, it is an example of cultural diffusion.
Explanation:Possibilism is a geographic concept that explains that the environment sets certain constraints or limitations, but culture is determined by the actions of humans, which can be independent of the environment. This differs from environmental determinism, where the environment is seen as the dominant influence on culture.
From the examples given, the one that is NOT an example of possibilism is 'The movement of people between regions promotes the spread of culture.' This is simply a statement about cultural diffusion, not about how humans adapt to specific environmental conditions.
The other options, such as 'People who live in dry, mountainous terrain develop sophisticated irrigation systems', 'People living in an arctic environment use snowmobiles to navigate the terrain', 'Fishing is an important source of food for people who live near the ocean', and 'People who live in hot, wet climates grow crops that thrive in these conditions' are all examples of possibilism; they reflect how humans adapt to and operate within different environmental conditions.

Why do many deserts exist at 30° north and south latitudes?a. The temperature is much higher at these latitudes; therefore, moisture evaporates much more quickly. b. Horizontal mountain ranges exist just above these latitudes, resulting in large rain shadows. c. At this latitude, cold air falls downward and becomes warmer, which means it can hold more moisture. d. This is a low pressure zone where air ascends, taking the moisture with it. e. These latitudes receive more solar energy than most other latitudes, making them much warmer and dryer than other areas.
Answer:
the answer is e
Explanation:
The deserts exist at 30° north and south latitudes because these latitudes receive more solar energy than most other latitudes, making them much warmer and dryer than other areas. Thus, the correct answer is option E.
What are latitudes?Latitude is a coordinate in geography that specifies the north-south position of a point on the Earth's surface or another celestial body. Latitude is expressed as an angle ranging from 90° at the south pole to 90° at the north pole, with the Equator at 0°. Parallels, or lines of constant latitude, run east-west as circles parallel to the equator.
The majority of the world's deserts are found between 30 degrees north and 30 degrees south latitude, where heated equatorial air begins to descend. The descending air is dense and warms up, evaporating a large amount of water from the land surface. As a result, the climate is extremely dry.
Therefore, the warm and dry climate at 30° north and south latitude leads to the formation of desert.

In geology, the term "transform fault potential" denotes the extent to which one tectonic plate could be moved along a major transform fault line, such as California’s San Andreas, by an instantaneous strain release, commonly known as an earthquake.
(A) the extent to which one tectonic plate could be moved
(B) the extent to which one tectonic plate could move
(C) the extent that one tectonic plate could be moved
(D) the extent of one tectonic plate moving
(E) the extent of the movement of one tectonic plate
Answer:
(A) the extent to which one tectonic plate could be moved
Explanation:
The transform fault is a zone where the two plates slide past one another and thus the result in the displacement of the large landmass. Due to the presence of the earthquakes and the formation of thin valleys and the splitting of the river beds such as in the San Andreas fault. And the transform fault potential is the potential that the tectonic plates can e be moved to the extent that the earthquakes can occur. The transform fault is found in the oceanic basin and is offset by the mid-oceanic ridges. Thus they form an interactive zone of the dextral zone of the plate movements.According to Milutin Milanković, which of the following are a contributing factor to ice-age cycles?

The Spratly Islands are small and barely above water at high tide, but they are geopolitically important. Many countries in the region and beyond, including the Philippines, Malaysia, Brunei, Vietnam, China, and Taiwan, have claimed territory here. Why are these islands geopolitically significant?
Answer:
The Spratly Islands are geopolitically significant because of the oil and natural gas deposits found in the bed of its territorial waters.
Explanation:
The Spratly Islands are an archipelago in the southwestern part of the South China Sea. The islands do not have a resident population, ports or harbors, but there are four airports. Currently, the archipelago is used as a fishing area.
The territory of the islands is disputed by six states: Vietnam, China, Taiwan, Malaysia, the Philippines and Brunei. Despite their tiny size, the islands of the archipelago are important in terms of presence in the region. In addition, studies indicate the presence of a significant amount of oil and gas. According to the US Department of Energy, up to 5.4 billion barrels of oil and up to 55.1 trillion cubic meters of natural gas are concentrated in the Reed Bank area of the archipelago.
About 45 islands are occupied by relatively small military contingents from Vietnam, China, Malaysia, the Philippines and Taiwan. The Brunei fishery area includes the southern reef, but Brunei has not made any official territorial claims.
