Because one might have other minerals in it as well
It is a terrestrial planet.
It was formed from gas and dust.
It was formed in a debris disk from colliding planetesimals.
Explanation:
The earth is one of the four terrestrial planets that orbits the sun and forms a significant part of the solar system.
The solar system is made up of the planets moving round the sun which is the star. The satellites moves round the planets. Also, there are other interplanetary bodies that moves in the solar system.
- According to the solar nebular theory, the earth was formed from a gas of intersellar dust which was rotating.
- Intense pressure and temperature led to the collapse of the core under gravitational pull. The core formed the sun.
- The debris disk accreted to form several planetesimmals from which the earth was derived.
- Most of the solid and denser materials were pulled in closely to sun and they are rock balls called terrestrial planets.
- The outer parts are gas giants.

In 1990 rice production= 350 million tons
In 1999 rice production = 400 million tons
400-350= 50 million ton increase
50/350=.1428 To calculate the percentage increase you divide the total amount increased by the initial amount to determine the percent.
Therefore the world rice production increased by approximately 14% from 1990 to 1999.
Acid rain damages the protective waxy coating of leaves and allows acids to diffuse into them, which interrupts the evaporation of water and gas exchange so that the plant can no longer breathe
