Answer: D) Monitor the sea level over set period of time.
Since global warming causes land ice to melt, that water goes into the ocean to raise sea levels. This is an effect of global warming.
Choices A through C are things to measure if you want to measure causes of global warming, so we can rule those out.
When an atom of the element lithium (Li) transfers an electron to an atom of the element fluorine (F), then the bond results between the atoms is ionic bond.
<h3>what is chemical bond? </h3>
A chemical bond is defined as the bond which holds atoms together in molecules.
Bonds arise due to the electrostatic forces present between positively charged atomic nuclei and negatively charged electrons.
<h3>Types of chemical bond</h3>
- Ionic bond
- Covalent bond
- Coordinate bond
<h3>What is Ionic bond ? </h3>
Ionic bond is defined as the transfer of electron from one atom to another atom.
Since, electron transfer from lithium to fluroine. Thus lithium get positive charge and fluorine occupy negative charge.
Thus, the bond form between lithium atom and fluorine atom is ionic bond.

A physical process is a process which do not change the substance structure only its shape or phase is changed. On the other hand, a chemical process involves the formation of new substances.

No. i can go from my house to New York and back in a day since my final destination is the same as my beginning no work is done. if i go 20 ft from the house and stay i would have done more work. displacement is the key
