How Seawater Becomes Salty
General Statement:
Two-thirds of the Earth’s surface is covered in water, and 97% of that is salty seawater. Only 3% of our planet’s water is fresh such as water in rivers, lake, and streams. This fresh water plays a big role in explaining how the sea becomes salty. Water moves around our planet in a cycle powered by the sun: from the sea, to the sky, to the land and then back to the sea.
Explanation:
When the sun heats the water in the sea, it changes into gas called water vapour and rises into the air, through a process called evaporation. After that, the water vapour turns back into liquid water while floating in the air, forming clouds through a process called condensation. Then this water eventually falls from the clouds in the sky as rain, sleet, hail or snow in which the process is also called precipitation. When these flows into streams and rivers, and eventually makes its way back to the sea.
Furthermore, the rain that falls from the sky contains small amounts of chemicals called carbon dioxide and sulphur dioxide which makes the rain slightly acidic. This acid can absorb small amounts of mineral salts, including sodium and chloride. These mineral salts are dissolved from the rocks which then enter the water.
Conclusion:
Thus, the main salt in seawater is sodium chloride. The rain water flows off the land and into the rivers and streams that lead all the way to the sea, carrying the dissolved salts along with it that makes the seawater salty.

Aurora Borealis
General Statement
The northern lights, or aurora borealis, are a spectacular, colorful display of light commonly seen in the night sky in the northern hemisphere. Auroras in the southern hemisphere are known as the southern lights or aurora australis. Both the northern lights and the southern lights are polar lights, or aurora Polaris, because they occur near Earth’s magnetic poles.
Explanation
Auroras occur when charged particles (electrons and protons) collide with gases in Earth’s upper atmosphere. Those collisions produce tiny flashes that fill the sky with colourful light. As billions of flashes occur in sequence, the auroras appear to move or “dance” in the sky.
Earth’s magnetic field steers the charged particles towards the poles. The shape of Earth’s magnetic field creates two auroral ovals above the North and South Magnetic Poles. That is why auroras occur almost every night in the northern sky, from August to May.
The aurora often appears as curtains of lights, but they can also be arcs or spirals, following lines of force in Earth’s magnetic field. Most are green in color, but sometimes you’ll see a hint of pink. Strong displays might also have red, violet and white colors. The lights typically appear in the far north – the nations bordering the Arctic Ocean – Canada, Scandinavian countries, Iceland, Russia and the state of Alaska. But strong displays can extend down into more southerly latitudes.
The colors in the aurora were once a source of mystery throughout human history. But science says that different gases in Earth’s atmosphere give off different colors when they are excited. Oxygen gives off the green color of the aurora, for example. Nitrogen causes blue or red colors.
Conclusion
So today the mystery of the aurora is not as mysterious as it used to be. Yet people still travel thousands of miles to see the brilliant natural light shown in Earth’s atmosphere. And even though we know the scientific reason for the aurora, the dazzling natural light show can still fire our imaginations to visualize fire bridges, gods, or dancing ghosts.

How Rain Happens
General Statement
Rain is one of the main sources of fresh water for almost all people in the world. It provides suitable conditions for diverse ecosystems. It is also used as hydroelectric power plants and crop irrigation. But, do you know how rain happens?
Explanation
The rain’s phenomenon is actually what we often call as “water circle.” The concept of the water cycle involves the sun heating the Earth’s surface water and causing the surface water to evaporate. Then the water vapor rises into the Earth’s atmosphere. The water in the atmosphere cools and condenses into liquid droplets. The droplets grow bigger and heavier and fall to the earth as precipitation.
Conclusion
