Answer:
Earthquakes happen when rock below the Earth's surface moves abruptly. Usually, the rock is moving along large cracks in Earth's crust called faults. Most earthquakes happen at or near the boundaries between Earth's tectonic plates because that's where there is usually a large concentration of faults.

Answer:
A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure. As such, it is one of the four fundamental states of matter (the others being solid, gas, and plasma), and is the only state with a definite volume but no fixed shape.
Air pollution is the addition of impurities to the atmosphere. A physicist would be concerned because pollutants can reduce sunlight reaching the earth and this quantity, radiation, would fall under the scope of a physicist. Physicists might also be concerned with the absorption of heat by certain pollutants. They would be concerned with studying how much heat is absorbed by each molecule to ascertain the impact of the entire contamination in the atmosphere.
Human use of land has negative impacts. Human activities contribute to the erosion and pollution of beaches. Deforestation of land can also lead to desertification and a loss of biodiversity.
Answer:
The coordination number is 4.
Explanation:
- Square planar clusters can be either cis or trans, as they form 180 and 90-degree bond angles. Therefore, a pair of ions may be adjacent (cis) to one another and immediately across (trans) from one another.
- A square planar molecule could never be simultaneously cis and trans, so because several coordinators are 4.
- Since linear complexes have only an angle of a bond of 180 degrees, they can not have cis or trans-isomers. In the coordination complex, there is only yet another way possible of bonding the two binding sites to the steel.
