Saturation Mixing Ratio

Water vapor in the air Liquid water can evaporate and turn into water vapor in the air. Conversely, water vapor in the air may turn back into the water. Some are very dry, with no moisture at all, such as … more

Continental Drift (Continental Drift Theory)

Move the continents to create a connected supercontinent (Pangea).

Seismic Wave

Investigation inside the Earth The surest way to see what the Earth is like is to penetrate and see it yourself. However, there is a limit to penetration because the temperature and pressure rise as you enter the Earth. Therefore, … more

Equilibrium

* If the simulation does not move, please refresh the web page. Radiation Places near the stove feel warmer than far away. This is due to the direct transfer of heat from the stove without the movement of matter. This … more

Stratum Making

About this simulation, When you press the button, you can see the corresponding strata. Combining the layer, you can create a variety of stratum. This simulation is presented as a mathematical model. Actual strata may be different.

Coriolis Effect

Coriolis effect The French mathematician Coriolis first explained that the direction of fluid movement on the Earth’s surface is slightly warped. You can observe this effect in all spinning places like Earth. The Coriolis effect causes the following: 1. In … more

Weather front and temperate cyclone

You can drag the screen to rotate it. Temperate cyclone (also known as Extra-tropical cyclone) The temperate zone is where the north’s cold air mass meets the south’s warm air mass. When two different chunks of air meet, they cannot … more

Atmosphere

Altitude-temperature data is based on ISA(International Standard Atmosphere). Values ​​other than the data were obtained using spline interpolation. Altitude(km) Air Temperature(℃) 0 15 4 -11 8 -37 12 -56.5 20 -56.5 30 -46.5 40 -22 50 -2.5 60 -26 70 … more

The Air Pressure and Wind

If you fill the Coriolis effect 100%, the actual wind on the surface of Earth will appear. High atmospheric pressure and low atmospheric pressure The cause of wind blowing is the difference in air pressure. A high-pressure system has higher … more

Sea and Land Breeze

Sea and Land Breeze Sea and Land Breeze is a wind that changes its wind direction every day in coastal areas. During the day, a sea breeze blows from the sea to the land, and at night, a land breeze … more

Torricelli’s Experiment

* You have to wear gloves when handling mercury. Torricelli’s Experiment The first person to measure the magnitude of air pressure is Italian scientist Torricelli. He was filled with mercury (Hg) in a glass tube with one end blocked. And … more

Galileo’s Pump Problem

Galileo’s Pump Problem A duke living in Tuscany, Italy, in the 17th century installed a well in the courtyard of the palace. But, the duke saw the pump fail to pull water up. The Duke asked Galileo for this. Galileo … more
