What is it called when the footwall block moves up relative to the hanging wall block? Reverse Faults • If the hanging wall moves up relative to the footwall, the fault is a reverse fault. Reverse faults are caused by compressional stress, or stress that pushes rocks together. Reverse fault. Which type of force is […]

Why does air pressure increase after a cold front passes?
Why does air pressure increase after a cold front passes? If the air is moist and unstable enough, rain and thunderstorms can accompany the passage of the front. Air pressure usually falls as a cold front approaches, rising rapidly after passage as the dense cold air moves in. The dew point falls indicating the change […]
What happens to the air pressure inside a balloon when the balloon is squeezed to half its volume at a constant temperature?
What happens to the air pressure inside a balloon when the balloon is squeezed to half its volume at a constant temperature? What happens to the air pressure inside a balloon when it is squeezed to half its volume at constant temperature? The atmospheric pressure decreases as they rise, so they expand. What causes pressure […]
What are the two types of charge?
What are the two types of charge? Summary There are only two types of charge, which we call positive and negative. The vast majority of positive charge in nature is carried by protons, whereas the vast majority of negative charge is carried by electrons. Can we produce heat by using our hands? Answer: yes we […]
Is speed always equal to velocity?
Is speed always equal to velocity? Common mistakes and misconceptions. Average speed does not have to equal the magnitude of the average velocity. People may think that average speed and average velocity are just different names for the same quantity, but average speed depends on distance and average velocity depends on displacement. Does speed mean […]
What is the character in hybridization of carbon when it exerts strongest effect a 25% B 50% C 75% D 100%?
What is the character in hybridization of carbon when it exerts strongest effect a 25% B 50% C 75% D 100%? The correct option is (b) 50%. This is because, in any hybridisation, there is no feasibility to have s character more than 50%. Thus, maximum -I effect is shown by sp hybridisation having 50% […]
What is the relationship between length and period?
What is the relationship between length and period? The longer the length of string, the farther the pendulum falls; and therefore, the longer the period, or back and forth swing of the pendulum. The greater the amplitude, or angle, the farther the pendulum falls; and therefore, the longer the period.) Is period directly proportional to […]
Why does the temperature of a substance not change when the phase changes?
Why does the temperature of a substance not change when the phase changes? But there is no temperature change until a phase change is complete. i.e. during phase change, the energy supplied is used only to separate the molecules ; no part of it is used to increase the kinetic energy of the molecules. So […]
