What happens when we move vertically upwards from the earth?
the atmosphere becomes thinner as we go upward from the earth
no
When we move vertically upwards from the Earth, we are essentially moving against the force of gravity. The force of gravity pulls objects toward the center of the Earth, so as we move upward, we are moving away from this force.
As we move upwards, several things happen:
1. Decrease in gravitational force: The farther away we move from the Earth's surface, the weaker the gravitational force becomes. This means that the force pulling us downwards gradually diminishes.
2. Decrease in weight: Since weight is essentially the force of gravity acting on an object, as we move upward, our weight will decrease. This is why astronauts experience weightlessness in space, where the gravitational force is very weak.
3. Decrease in air pressure: As we move higher in the atmosphere, the air pressure gradually decreases. This is because the weight of the air above us decreases, resulting in lower atmospheric pressure.
4. Drop in oxygen levels: As we ascend vertically, the concentration of oxygen in the atmosphere decreases. This is why climbers scaling high mountains often require supplemental oxygen.
In summary, when we move vertically upwards from the Earth, we experience a decrease in the force of gravity, weight, air pressure, and oxygen levels.
