Magnetosphere: Satellites, Space Debris, and What Else?

July 10, 2020

Without the magnetosphere, the Earth’s atmosphere would have been destroyed by the solar wind long ago. It stretches way beyond satellites’ reach, and is affected both by the Earth and the Sun. It protects humans, living on both Earth and in space, from the high-energy particles. […]

Low Earth Orbit: Troposphere and Stratosphere

July 9, 2020

The atmosphere has numerous layers, two of the most important of which are the troposphere and stratosphere. The significance of these layers in human life lies in things that happen there: weather and its components, planes and their passengers, and about 80% of the atmosphere’s mass. […]

The Coriolis Effect, Earth’s Spin, and Its Consequences

July 5, 2020

The Coriolis effect is caused by Earth’s rotation around its axis. The effect is the strongest at poles and reaches almost zero at the equator, leaving the equator areas with no storms and hurricanes. The effect can be seen in large-scale movements, not throwing paper airplanes or buckets of water. […]

Air Resistance, Drag Force, and Velocity: How Falling Works

July 5, 2020

Gravity is not the only force involved in falling or throwing. Gravity determines weight, but the object’s shape and surface area determine how much resistance it will experience when falling or flying. Air resistance, drag, and the speed of the moving object also affect the motion. […]

Mathematics of Falling: The Parabolic Movement

July 5, 2020

The parabolic movement of objects that are ‘thrown’ is predictable through math. Even though what happens in physics is usually different from a perfect parabola due to the effects of other elements and the environment, math can still help calculate the movement and its shape. […]

Plate Tectonics Play a Crucial Role in Sustaining Life on Earth

July 4, 2020

The tectonic plates drift around—moving continents, causing earthquakes and volcanoes and determining the composition of the air we breathe. Plate tectonics play a major role in making our planet so vibrant and abundant, as well as sustaining life on Earth. […]
