The movement of Earth's lithosphere is caused by convection within the_____(crust, core,mantle) layer of the earth.

The correct answer is - 4.543 billion years.

Our planet, the Earth, is considered to have formed approximately 4.543 billion year ago. It is thought that the Earth had formed at roughly the same time with the other planets, or rather they all formed in a relatively small space of time.

The Earth is part of the inner planets, and it is the the third most closest to the star in our galaxy, the Sun. Also, it is the only planet on which is known that life can exist, at least so far, as it is the only planet that provides the right conditions for the development of living organisms.

The biggest interaction that the Earth has is with the gravitational pull of the Sun and the Moon, the only natural satellite of the Earth.

The currently accepted age of Earth is estimated to be between 4.4 and 4.57 billion years based on scientific methods, including radioactive dating. This greatly surpasses the previously believed age of 6,000 years, providing important context for the development of life on Earth.

Answer:

Tectonic processes has played most important role in shaping the physical landscape of east Africa.

Explanation:

A rift valley is a swamp area that appears where Earth's tectonic plates shift apart or rift. Rift valleys occur both on land and about the depths from the ocean, where all are formed by the process of seafloor expanding. Tectonic plates are tremendous, rocky parts of Earth's lithosphere—its outside and above the mantle.

Earth has so few impact craters compared to the Moon because of erosion, plate tectonics, and volcanoes.

1. Erosion

Weather, running water, and plants all wear down the ground and level it out. The moon has none of these.

2. Plate tectonics

The Earths surface consists of several tectonic plates floating over a liquid core.

As the plates tear apart and crush against each other, new rocks form and older ones disappear.

Over billions of years, all traces of old impact craters have disappeared.

The moon has no moving plates, so tectonics cannot remove lunar craters.  

3. Volcanoes

Volcanic flows cover up impact craters. The Moon has not had active volcanoes for three billion years.

Earth has fewer visible impact craters than the Moon due to three main processes: plate tectonics, which recycles the Earth's crust; volcanism, which buries craters under lava and ash; and erosion, which weathers away and fills in craters.

Earth's surface is considered "young" compared to the Moon because it exhibits few visible impact craters. Despite being struck by interplanetary debris at about the same rate as the Moon, Earth's craters have largely been erased due to several key processes:

These geological activities are largely absent on the Moon, which is why its surface is saturated with craters, offering a stark contrast to Earth's rejuvenating landscape. The years of geological formation and erosion on Earth speak volumes about its active history and evolution of life which was significantly influenced by such impactful events.

A mid-1600s map of North America showcases colonial settlements by European powers, depicting territorial competition and impact on indigenous cultures and socioeconomic structures.

When examining a map of colonial European settlements in North America from the mid-1600s, it reveals a complex tapestry of territorial claims and settlements by various European powers, including the English, Dutch, French, and Spanish. Each European nation sought to expand its empire, with settlements often strategically located to access resources, trade routes, and support military endeavors. The presence of Native American tribes is also noted, highlighting the rich indigenous cultures that existed before European colonization. The geopolitics of the era was marked by competition and conflict, as these powers vied for control and influence over the New World. This period also saw the introduction of slavery and significant shifts in agriculture, which had a profound impact on the social and economic fabric of the continent.

The composition and structure of Earth's layers vary as we go deeper. Starting from the thin crust made of silicate rocks, we move to the mantle with increasing density, and finally to the iron-rich, differentiated core with both solid and liquid parts.

The composition and structure of Earth's layers change as one goes deeper into the Earth. The layers include the crust, the mantle, and the core.

The Earth's outermost crust is a thin layer, no more than a few kilometers deep. It is predominantly composed of silicate rocks. Beneath the crust is the mantle, which can deform and flow slowly. The mantle's density increases from about 3.5 g/cm³ to more than 5 g/cm³ as one goes deeper, due to the compression produced by the weight of overlying material. The mantle comprises of upper and lower portions, with different compositions and physical behaviors.

Beyond the mantle is Earth's core, divided into an outer and inner core. The outer core, which is liquid, and the inner core, which is solid, largely consist of iron. However, other elements like nickel and sulfur are also present. Overall, studying the Earth's interior is challenging, and much of what we know comes from indirect evidence, like the study of seismic waves from earthquakes.

Answer:

74.02%

Explanation:

Mass percentage -

Mass percentage of A is given as , the mass of the substance A by mass of the total solution multiplied by 100.

i.e.

mass % A = mass of A / mass of solution * 100  

Given,

mass of carbon = 12 g/mol

mass of  nitrogen = 14 g/mol

mass of hydrogen = 1 g/mol

Hence , the mass of solution is calculated as the summation of the  mass of the atom * number of atom ,

Hence ,

mass of solution =  10 * 12 g/mol + 14 * 1 g/mol + 14 * 2 g/mol = 162 g/mol

Mass of carbon = 10 * 12 g/mol = 120 g/mol

The mass percent of carbon can be calculated from using the above formula

mass % C = mass of C / mass of solution * 100

mass % C = 120 g/mol / 162 g/mol * 100

mass % C = 74.02% .

there are woods and hills and such, there could also be more water to cross

Answer:

The Mississippi River and its alluvial plain houses a rich fauna and flora that make up the largest marsh system in the North American continent, therefore, the settler must cross this system in order to settle.

Explanation:

The marshes are wet-type ecosystems with the presence of water, as well as a low and superficial vegetation that covers all the water but does not dry it. This system is usually found in regions near the sea.

The marshes, depending on the depth of the terrain, can become navigable. They are able to trap and bind sediments, so they act as a filter for pollution. They constitute a habitat for animals, especially migratory birds that use the marshes as a place to rest and feed during their long trips.

The type of goods that is interchangeable with another good fungible.  

Further Explanations:

Fungible goods are those goods that are substitutable as they are alike to each other as per practical use. Commodities, mutual shares, opportunities, and dollar bills are some such illustrations of fungible goods. It is also defined as the commodities are having nature of being replaced by another such like commodity or quantity in paying a dues or settling an account.Oil, wheat, and lumber are also considered as fungible commodities.  

Substitute goods are defined two unusual goods that can be used for the similar purpose. If the cost of one commodity upsurges, then demand for the substitute upsurges proportionally. Therefore, a substitute lays a “positive cross elasticity” of demand. While, normal goods are those goods experiences increase in its consumption due to a surge in the consumers’earnings.

The great rocky mountains

Answer:

Environmental Influence:

Administrative Circumstances and Management Policies

Commercial Circumstances

Ancient Circumstances

Explanation:

Temperature and rain are the two main important climatic factors. Regions of great attitude own low population because of very low temperatures encountered. Solid forests are sparsely populated. It is challenging to contract a transmission line in such regions. Excellent seepage areas pull settlement and therefore have the high populated areas. Muddy places and regions with periodically sloughs are normally unsettled. Past effects may also be effective for low population quantities in some areas. Financial development rising from exercises such as the exploitation of native resources lure a large group of job-seekers and assistance providers.

Population density varies due to factors such as economic opportunities, climate, geography, and infrastructure. Areas with fertile land, water sources, and favorable climate attract more people. In contrast, harsh environments or lack of resources lead to lower population densities.

Population is denser in areas with economic opportunities due to the availability of jobs and better living standards. Cities and urban areas tend to attract more people because of industrialization and services.

Climate and geography play a crucial role. Regions with a temperate climate and fertile soil can support agriculture and sustain larger populations. River valleys and coastal plains are examples of such areas.

Infrastructure is another important factor. Well-developed transportation, healthcare, and educational facilities make an area more attractive. Areas lacking good infrastructure typically have lower population densities.

Lastly, political stability and security also influence population distribution. People tend to migrate away from conflict zones to safer, more stable regions.

Sediments are defined as solid fragments of inorganic or organic material.

So I believe the answer is right let me know

The tide will be neap tide.

The moon has the strongest effect on the rise or fall of the tides due to its gravitation pull. The normal tides are always present in the ocean at different hours of a day. But in spring tides, the moon has its full phase, it has the strongest effect on the tides as high tides convert to highest tides and low tides to the lowest tide. In the neap tide, the low tide converts to lowest high tide and high tide converts to a highest low tide which makes the extreme difference between high and low tide.

Final answer:

A spring tide has the greatest difference between high and low water, creating the highest high tides and the lowest low tides, which occur near the times of new and full moons due to the aligned gravitational forces of the moon and the sun.

Explanation:

The type of tide with the greatest difference between high and low tide is known as a spring tide. It occurs near the times of the new and full moon when the gravitational pull of the moon and the sun are aligned. The combined gravitational forces exert a stronger pull on the Earth's oceans, leading to higher high tides and lower low tides, thus increasing the tidal range. Contrary to spring tides are neap tides, which occur during the moon's first or third quarter when the sun and moon are at right angles to each other, resulting in a smaller difference between high and low tides.

According to definitions provided in educational materials, it is during the spring tides that one may observe some rocks or shoals that are continuously covered by the sea at one time being laid bare at another. This tidal phenomenon is observed globally and is an essential aspect of oceanography. Coastal areas may experience different tidal patterns such as mixed semidiurnal, semidiurnal, and diurnal tides, but it is the spring tide that has the most significant tidal range.
