- Q1: What is the pressure exerted by the air in the atmosphere called?
Answer: Atmospheric
Explanation: The air around Earth exerts pressure, which is known as atmospheric pressure. - Q2: What instrument is used to measure atmospheric pressure?
Answer: Barometer
Explanation: A barometer helps measure the amount of pressure exerted by the atmosphere. - Q3: What layer of gases surrounds the Earth and creates atmospheric pressure?
Answer: Atmosphere
Explanation: The blanket of air surrounding Earth is called the atmosphere, which exerts pressure. - Q4: Which gas exerts pressure in all directions in the atmosphere?
Answer: Air
Explanation: Air molecules constantly move and collide, exerting pressure in all directions. - Q5: What causes the atmospheric pressure to exist on Earth’s surface?
Answer: Weight
Explanation: The weight of air above us creates atmospheric pressure on the surface of the Earth. - Q6: What happens to atmospheric pressure as altitude increases?
Answer: Decreases
Explanation: As you go higher, the amount of air above you decreases, reducing atmospheric pressure. - Q7: What is experienced when air pressure pushes on the surface of our body?
Answer: Force
Explanation: The atmospheric pressure acts as a force over the surface area of the body. - Q8: What allows a suction cup to stick to a surface?
Answer: Pressure
Explanation: Air is pushed out from inside the suction cup, and atmospheric pressure outside holds it tightly. - Q9: What balances the atmospheric pressure on our body from inside?
Answer: Blood
Explanation: The pressure of blood and other fluids inside our body balances the atmospheric pressure outside. - Q10: What is reduced inside a vacuum that causes external air to crush a can?
Answer: Pressure
Explanation: When air is removed from inside a can, external atmospheric pressure crushes it due to imbalance.
