Where and when did the largest magnitude earthquake occur in the united states?

Silicon and _______ stay in the the outer cells pls tell me fast

mario62 [17]

Answer:

Oxygen

Explanation:

The earth has been divided into three major categories crust, mantle, and core which are further segregated into sub-parts. Since the crust is the outermost layer of the shell, the outer crust of the earth consists of a combination of silicon and oxygen in the majority followed by some percentage of other metals as well. <u>The percentage of Oxygen includes nearly 50% i.e. 46.6% followed by 27.7% of Silicon and the other 25.3 % includes aluminum, iron, sodium, magnesium, etc</u>. Thus, '<u>oxygen</u>' is the correct answer.

How does gravity affect the movement of plates at mid-ocean ridges?

vazorg [7]

Answer:

Convection currents push up on parts of the plate. Then gravity pulls on those areas, bringing them downward. And, as these areas move lower, the ridges then push the plates away and outward.

The distance from Alexandria to Syene is about 500 miles. On the summer solstice the sun is directly overhead at noon in Syene.

svp [43]

Answer:

Earth circumference is 25000 miles

correct option is 25,000 miles

Explanation:

we have given here Alexandria to Syene distance = 500 miles

the sun is 1/50th of the circumference of the sky (about 7°)

as we know that Earth circumference done by astronomer Eratosthenes in 240 B.C

He observe on a particular time of day ( in noon) during the summer solstice

and there was no shadow in Syene in Egypt so This was verified that the sun must be directly on overhead and not at an angle to the surface of the city at that time

so

In Alexandria he measured the position of sun at the same time and found it to be nearly (1/50)th of a complete circle

it would be 7.2 degree (when we do $\frac{360}{50}$ = 7.2)

so 2 reference points being 2 cities for the sun

all measure circumference = the distance between these two cities × 50

and we have given 500 miles

so

Earth circumference = 500 × 50

Earth circumference is 25000 miles

correct option is 25,000 miles

What is China’s major land problem?

stira [4]

Property rights. The rapid growth of cities has led to government transfers of rural land to urban and industrial uses. Inadequate compensation to farmers whose property rights have been poorly defined has fueled growing civil unrest, while urban leaseholders seek to strengthen their new property rights.
Property tax implementation. Recent tax reform has reduced local government revenues and prompted local officials to rely on land sales receipts, fees, and off-budget revenues to finance government expenditures. China’s government is seeking to implement a property tax as a local revenue source to take advantage of the rapid growth of the real estate market.
Farmland preservation. The large amount of land removed from agricultural production by the complex forces of urbanization has exacerbated concerns about farmland preservation, especially related to food security.
Urban planning and development. Rapid urbanization has also resulted in increased urban poverty, housing affordability problems, inequality between urban and rural population groups, regional disparities, and other social and economic challenges. China’s urban planning practices are in need of reform to better reflect market forces and economic behavior.
Environmental sustainability. China’s economic and demographic changes over the past 30 years have been associated with severe environmental degradation. With rapid urbanization forecast over the next decade, there is growing consensus that China must find a more sustainable development model. More sustainable cities are integral to any low-carbon development trajectory.
