Answer:
B. P waves can travel through liquids
Explanation:
P waves or primary waves are elastic waves produced from an earthquake. They are the first waves that arrives a Seismic station when an earthquake disturbs the earth.
P and S waves are both body waves that moves within the earth.
P- waves travel faster than S- waves and can propagate through any medium. S-waves or Secondary waves are shear waves that can only propagate through soilds.
Both waves are longitudinal and moves parallel to their source of propagation. They move by disturbing other particles in their line.
Transverse waves are the love and rayleigh waves. They are both surface waves that travels and cause disturbance on the surface of the earth during an earthquake. They move up and down.

Answer:
The relationship between the warming of the earth’s northern latitude and ice is a practical example of a positive feedback on the earth system.
Explanation:
A positive feedback is a process that brings about an increase in the process of interaction in the earth activities The warming of the northern latitude which is responsible for generating more heat through sunlight with time, usually results in an increase in the melting of ice bodies in the ocean by movement. This activity is regarded as positive because it is associated with an increase in the process. This process is directly proportional to the exchange activities that takes place and often leads to an equilibrium in the earth system.
