Approximately what per cent does Central America contribute to the total amount of carbon dioxide produced in the world?

Assume that the Moon is hit by about 25 million micrometeorite impacts each day (this number comes from observations of meteors

mestny [16]

Answer:

3.03 Billion Days or 8.30 Million years

Explanation:

Given,

No. of micrometeorite impacts per day on the Lunar surface = 25000000

Impacts needed to erase a footprint = 20

Area of footprint = 300 cm²

We know that surface area of the Moon = 37.93 Million Km² = $37.93\times 10^{16} cm^{2}$

To find: How long will it take to erase one footprint?

Using the above information,

No. of impacts per cm² per day is

$= \frac{25000000}{37.93\times 10^{16}}$

No. of impacts on area of a foot print (300 cm²) per day will be,

$= \frac{25000000}{37.93\times 10^{16}}\times 300$

$= 6.59\times 10^{-9}$

To erase the footprint there must be 20 impacts on the area of footprint.

Time taken for $6.59\times 10^{-9}$ impacts = 1 Day

Time taken for 1 impact is

$= \frac{1}{6.59\times 10^{-9}} days$

Hence, time taken for 20 impacts will be

$= \frac{1\times20}{6.59\times 10^{-9}} days$

$= 3.03 \times 10^{9} days$

$= \frac{3.03 \times 10^{9}}{365}years$

$= 8.30 \times 10^{6} years$

It would take around 3.03 Billion Days or 8.30 Million years for one of the footprints left by the Apollo astronauts to be erased.

Briefly describe how buoyancy, isostatic equilibrium, and epeirogenic processes are related.

nataly862011 [7]

<h2><u>Relation between buoyancy, isostatic equilibrium, and epeirogenic processes</u></h2>

Buoyant force or buoyancy, is the force exerted in an object which is fully or partially occupied in a fluid. Isostatic equilibrium is the gravitational equilibrium between earth's crust and underlying mantle. while epeirogenic process is the depression of land having long wavelengths.

Both epeirogenic process and isostatic equilibrium uses the principle of buoyancy. The crust of the Earth or the lithosphere floats over underlying mantle at an elevation depending upon its density and thickness.
