These smaller pieces of rock (such as sand, silt, or mud) can be deposited as sediments that, after hardening, or lithifying, become sedimentary rocks. Extreme pressure from burial, increasing temperature at depth, and a lot of time, can alter any rock type to form a metamorphic rock.

Calculate the total mass of water in kg on Earth's surface from the following data: total planetary surface area: 510,066,000 km

irinina [24]

Answer:

The total mass of water in on Earth's surface is $3.61419\times 10^{22} kg$ .

Explanation:

Total planetary surface area = T = $510,066,000 km^2$

Total land area of planet = L = $148,647,000 km^2$

Total water area of planet = W

T = L + W

$510,066,000 km^2=148,647,000 km^2-W$

$W=510,066,000 km^2-148,647,000 km^2=361,419,000 km^2$

Volume = Area × Depth

Volume of water on earth = V

V= $361,419,000 km^2\times 100 km^=36,141,900,000 km^3$

$km^3=10^{12} L$

$V=36,141,900,000 km^3=36,141,900,000 \times 10^{12} L$

Total mass of total water on the earth = M

Density of the water,D = 1 g/mL = 0.001 kg/0.001 L=1 kg/L

1 g - 0.001 kg

1 mL = 0.001 L

$D=\frac{M}{V}$

$M=D\times V$

$M =1 kg/L\times 36,141,900,000 \times 10^{12} L=3.61419\times 10^{22} kg$

The total mass of water in on Earth's surface is $3.61419\times 10^{22} kg$ .

Answer:

(b) Decompression melting , flux melting

Explanation:

Decompression melting : The procedure of decompression melting includes the upward development of the earth mantle to a zone of lower pressure. The decrease in overlying weight empowers the stone to melt, prompting magma arrangement. Magma is shaped by the melting of the earth mantle.

Flux melting :I n molten petrology and volcano logy, flux melting happens when water and other unstable segments are added to hot strong shake. In designing and metallurgy, transition is a substance, for example, salt, that creates a low dissolving point blend with a metal oxide.

Similarly, the expansion of water and other unstable mixes to rocks made out of silicate minerals brings down the softening temperature of those stones.

Why do you think that people of every nationality and ethnicity live in Hong Kong (At least 3 sentences in your own words).

rusak2 [61]

Despite Hong Kong historically being part of China and being inhabited by Chinese people, that drastically happened in the last century. Hong Kong got into the hands of the European colonial powers, and even after they left the area, they didn't left Hong Kong. The reason why the presence in Hong Kong was kept was because of its excellent strategic position.

The newly formed nation had excellent ports and excellent location. It was quickly industrialized. That led to rapid economic growth. The economic growth and the prosperity of the small nation made, as well as it deep connections with the Western World, attracted lot of people to move in it. The Chinese population is still dominant, but over time people from all over the world moved in, thus the ethnic structure of this nation changes significantly, to a point where now it has citizens from pretty much every corner of the world.
