Answer:
Volcanoes are created over approximately 10,000-500,000 years by thousands of eruptions -- each lava flow covering the one before it. In the case of oceanic island volcanoes, lava erupts first from fissures, or cracks, on the deep ocean floor. The flows continue to build up and finally an island emerges from the sea.

Meninges and cerebrospinal fluid both protect the brain from physical shock.
Meninges is one of the membranes that engulf the brain .
Cerebrospinal fluid is the fluid that the brain floats in and absorbs shocks. #answerwithquality #BAL
Answer:
P wave
Explanation:
Electrocardiogram records the strength and timing of electrical activity in heart. As various regions of heart contract at different times and for different duration, the electrical activity is not constant and shows a series of rise and fall. There are three main components of ECG: P wave, QRS complex and T wave.
P wave indicates the beginning of electrical signal in the right atrium. The signal spreads in both right and left atria which leads to their contraction. As a result, blood is pumped into the ventricles and rest of the process occurs.
Yes, the specific heat capacity of substances change when there is a change in temperature. At molecular level, the internal energy of a substance is stored in form of translational, rotational and vibrational energy. It has 3 degrees of freedom for each form of energy. In lower temperature ranges, say below 1000 degree celsius, vibrational energy is insignificant.
