Covalent bonds are formed when two atoms are able to <em>share</em> electrons.
Iroinic bonds are form when two atoms are <em> </em> electrons from each other to complete the bond. This results in a pair of ions.
<u>Covalent bonds:</u>
- Have a definite shape.
- Have a low melting point.
- At room temperature they are in a liquid or gas.
- They occur between two non-metals.
<u>Ionic bonds:</u>
- Have no definite shape.
- Have a high melting point.
- At room temperature they are solid.
- They occur between a metal and a nonmetal.
What is the question here? There’s multiple answers
Pine trees have deep roots which enable them to adapt to the climate of the northwestern coniferous forests. Their roots extend deep down to the soil where oxygen content is limited and water is scarce. During the change of seasons when the soil is wet the roots tend to recede and when it is dry the roots tend to spread downward.
The process of subduction and sea floor spreading can change the size and shape of the oceans. I Hope This Helped! (Mark as Brainliest If You Agree!)
