All continents fit together with the least number of overlaps and gaps when the continents are matched along:________
A) contours at around 2,000 meters depth.
B) current shorelines.
C) edge of the continental shelf.
D) edges of the deep sea floor.
E) oceanic trenches in subduction zones.

Answers

Answer 1

Answer:

A) contours at around 2,000 meters depth.

Explanation:

As the contours of the world when measured from a 2000 meters depth shows us the same orientation and fitting f the continental shelf sand the plates as the lines joined the place as they are then overlapped and hence are connected by the values that are assigned to them.
Answer 2

Final answer:

All continents fit together with the least number of overlaps and gaps along the edge of the continental shelf, which is the underwater extension of the continent before the continental slope.

Explanation:

The continental shelf is the ocean floor nearest the edges of continents, characterized by a gentle slope and shallow waters, usually extending about 100 to 200 kilometers from the shore up to the shelf break. This feature represents where the continental crust continues underwater before reaching the steep continental slope.

While options such as contours at around 2,000 meters depth, current shorelines, edges of the deep sea floor, and oceanic trenches may seem plausible, they do not represent the precise match points that existed when the continents were once connected. Oceanic-continental convergence, which shapes features like trenches and submarine canyons, occurs at plate boundaries but is not where continents would seamlessly connect.

"Flat-lying sedimentary strata or volcanic rock layers may erode to form isolated structures called"

Answers

Final answer:

Isolated structures formed from flat-lying sedimentary strata or volcanic rock layers by erosion are called monadnocks or inselbergs, which are resistant to weathering and provide geological insights.

Explanation:

Flat-lying sedimentary strata or volcanic rock layers may erode to form isolated structures called monadnocks or inselbergs. These formations are a result of the erosion of surrounding softer materials leaving the more resistant rock layers exposed as prominent, isolated structures. The structures give insights into the geological past and can indicate the presence of ancient mountain ranges or plateaus that have since been worn down through weathering and erosion while the harder monadnocks have resisted these forces.

Characteristics of passive continental margins include which of the following? a.Volcanic and earthquake activity b.Broad continental shelves c.Chains of islands d. Deep-sea trenches e.Thin sediment accumulation

Answers

Answer:

(B) broad continental shelves

Explanation:

Passive continental margins have broad continental shelves

Many passive continental margins have a continental rise, a very low‐angle ridge of sediment that forms between the continental slope and the abyssal plain.

Final answer:

Passive continental margins are characterized by broad continental shelves and thin sediment accumulations, with a noticeable lack of tectonic activity like earthquakes or volcanoes. They don't feature chains of islands or deep-sea trenches.

Explanation:

The characteristics of passive continental margins include mainly vast, broad continental shelves and thin sediment accumulation. Unlike active continental margins, passive margins are not associated with plate boundaries, so they do not witness much volcanic or earthquake activity. They do not have chains of islands or deep-sea trenches. These features - chains of islands, deep-sea trenches, volcanic and earthquake activity - are characteristic of active rather than passive margins. Passive continental margins are typically marked by a lack of tectonic activity, broad, gently sloping shelves, and thick accumulations of sediment eroded from the adjoining continent.

Answers

Answer:C. continental-interior desert.

Options:

A. rain-shadow desert.

B. polar desert.

C. continental-interior desert.

D. desert that forms because cold, dense air cannot rise to form clouds.

Explanation:

Deserts are dry areas which receive low rainfall, less than ten inches annually, or experience much higher evaporation compared to the annual rainfall received.  

The Gobi desert is an example of a continental interior desert. These are deserts located in the center of continents, far from oceans or other large water bodies. Therefore, the winds that reach these deserts lose all humidity due to their distance from the coast.

Final answer:

The Gobi Desert's remote location away from the ocean and behind the Himalayas classifies it as a high-altitude cold desert with arid conditions and cold winters.

Explanation:

The Gobi Desert in the interior of Asia is situated over 2,000 km from the nearest ocean, providing a classic example of a high-altitude cold desert. Its remote location, beyond the influence of oceanic moisture due to distance and physical barriers like the Himalaya Mountains, contributes to its arid conditions.

Furthermore, the Gobi, along with the Taklimakan Desert in western China, and several others, are subject to freezing temperatures in the winter, distinguishing them as cold deserts, a subtype of deserts characterized by cold weather and snowfall as the primary form of precipitation.

These vast and harsh environments are part of the greater Central Asian region, which includes extensive treeless, grassy steppes surrounding the deserts, often linked with the steppes of Eastern Europe geographically.

Why did the policy of treating the great plains as a huge reservation change?

Answers

Answer:

Policy of treating Great Plains as a huge reservation changes because white settlers began wanting land on the plains.  

Explanation:

Settlers are the one who migrate from the other area to that new one. Jamestown, Virginia was the place where first colony was established and many people settle there as they were persecuted by various regions in 1607. In '1770', more than '2 million' people settled to 13 northern American colonies. Because of more people settling there, reservation policy changed. 
Final answer:

The policy of treating the Great Plains as a huge reservation changed due to increased demand for land by settlers, leading to constant displacement of Native Americans. Policy changes, like the Dawes Act of 1887, further encouraged assimilation of Native Americans into American society and the transition from collective reservation system to individual land ownership.

Explanation:

The policy of treating the Great Plains as a huge reservation changed mainly due to settlers' increasing demands for land for farming, mining, and ranching. As the pace and number of western settlers increased, territories initially allocated to the native tribes under the Treaty of Fort Laramie became prime locations for these activities. The reserved lands, often poor and unsuitable for traditional occupations of most western tribes, resulted in failed agricultural attempts and made tribes heavily reliant on the Bureau of Indian Affairs for support.

As tribal lands became increasingly desirable for white settlement, Native Americans faced waves of displacements. The U.S. government abandoned treaties and empowered local or state militia units to forcibly remove tribes from their lands. Meanwhile, an Americanization policy was adopted, aimed at assimilating Native Americans into American society. This included transitioning them from the collective reservation system to individual land ownership, promoting Christian worship and providing education for children.

The Dawes Act of 1887 further facilitated this process by allowing the government to dissect reservation land into individual allotments for natives and white settlers alike, diminishing the strength of native tribes as collective entities. This shift in policy marked a significant change in the U.S. government's approach towards Native American tribes, resulting in their increased assimilation into American society and a profound transformation of the Native American way of life.
