I NEED THIS ASAP <br><br> Describe or define transform plate boundary
ohaa [14]
The most famous example of this is the San Andreas Fault Zone of western North America. The San Andreas connects a divergent boundary in the Gulf of California with the Cascadia subduction zone. Another example of a transform boundary on land is the Alpine Fault of New Zealand.

Which pair of atoms would form a covalent bond ?
Liula [17]
I think O and Cl will form covalent bonds since they are both non-metals and don't have a large enough difference in electronegativities to create an ionic bond.

I hope this helps.  Let me know if anything is unclear.

When water is released from a dam, what happens?
malfutka [58]

Answer:

Potential energy is transformed to kinetic energy

Explanation:

Once a river is dammed it changes its physical and chemical structure. Damming also changes the biological communities associated with the river and its floodplain. When water is kept behind dams, seasonal flow patterns are usually lost.

A hydroelectric dam converts the potential energy stored in a water reservoir behind a dam to mechanical energy—mechanical energy is also known as kinetic energy. As the water flows down through the dam its kinetic energy is used to turn a turbine.
