Explanation:
An object can possess energy in tow ways by it's motion or position
Answer:
Weathering involves the use of water and or wind to wear down the environment. The sand dunes were most likely carried by wind to form them and form its shape. Erosion most likely took away parts of the sand to make the sand dune. Deposition most likely deposited sand to the area.

The Lithium-ion Battery Problem
Overheating. They overheat and explode if charged too fast.
Short life time. They die after less than 1,000 charge/discharge cycles.
Flammable. They use chemicals that are flammable. ...
Toxic. ...
Underperform in extreme temperatures. ...
Expensive casing. ...
Expensive to transport.
To figure out the ratios of these compounds, it is important to remember that the charge of these compounds must be <em>
neutral</em>.
So in order to make them neutral, you must have specific ratios:
![Na^{+}: Br^{-} =1:1](https://tex.z-dn.net/?f=Na%5E%7B%2B%7D%3A%20Br%5E%7B-%7D%20%20%3D1%3A1)
; This is true because they both have a charge of magnitude of 1.
![Al^{3+}: Cl^{-}=1:3](https://tex.z-dn.net/?f=%20Al%5E%7B3%2B%7D%3A%20Cl%5E%7B-%7D%3D1%3A3%20%20)
; We need 3 chlorine atoms because we need to balance out the charge from the 3+ charge of aluminum - therefore since chlorine has a 1- charge, we need 3 atoms.
![Mg^{2+}: O^{2-}=1:1](https://tex.z-dn.net/?f=Mg%5E%7B2%2B%7D%3A%20O%5E%7B2-%7D%3D1%3A1)
; The charges of the magnesium (2+) are balanced with the oxygen charge (2-).
![Al^{3+}: O^{2-}=2:3](https://tex.z-dn.net/?f=%20Al%5E%7B3%2B%7D%3A%20O%5E%7B2-%7D%3D2%3A3%20%20)
; This is correct because if charges are like this, you must find the least common factor in order to know the ratio. The LCF is 6, therefore, for the atom with a 3+ charge, you need 2 of them, and for the atom with a 2- charge, you need 3 of them. This keeps the charge neutral.
