Answer:
Back into the sky and sewers/drainage holes
Explanation:
Water becomes evaporated from the sun and Rain also goes into drainage holes
A.They all have similar chemical properties
The mantle is mostly rich in iron and magnesium oxides and silicates. The mantle is usually divided into the Upper and Lower mantle separated by a transition zone that is smaller than the one that exists between the Inner and Outer core.
Some key things to remember when discussing states of Earth's structure are:
1. Temperatures are highest at depth and increase as you go towards the surface
2. Materials are thicker at depth, with high viscosity, due to increased pressure
Therefore, rocks in the lower mantle are at a high enough temperature that they become soft and are able to flow slowly.
The number of silicon atoms in atypical computer chips(0.001g of silicon) is 2.14 × 10¹⁹ atoms
The atomic mass of silicon = 28.0855 amu
Using the mole concept that 1 mole = 6.022 × 10²³.
This number is called the Avogadro's number.
Therefore,
1 mole / 28.0855g of silicon contains 6.022 × 10²³ atoms of silicon
0.001 g will contain ? atoms of silicon
cross multiply
number of atoms of silicon = 6.022 × 10²³ × 0.001 / 28.0855
number of atoms of silicon = 6.022 × 10²⁰ / 28.0855
number of atoms of silicon = 2.14 × 10¹⁹ atoms
