This is salt water. This is fresh water. What's the difference? Salt water contains a high concentration of dissolved salts, mainly sodium chloride, and makes up about 97% of Earth's water. It is found in oceans and seas and is generally not safe to drink without desalination. Fresh water contains very little dissolved salt and makes up only about 3% of Earth's water. It is found in rivers, lakes, glaciers, and underground sources and is the main source of drinking water. This is a tornado. This is a hurricane. What's the difference? A tornado is a rapidly rotating column of air that extends from a thunderstorm to the ground. It is usually smaller in size but can produce extremely powerful winds over a short distance. A hurricane is a large tropical storm that forms over warm ocean water. It can stretch hundreds of miles across and bring strong winds, heavy rain, flooding, and storm surges. This is an earthquake. This is a tsunami. What's the difference? An earthquake occurs when energy is suddenly released beneath the Earth's surface, causing the ground to shake. It is usually caused by movement along tectonic plate boundaries. A tsunami is a series of massive ocean waves most commonly triggered by an underwater earthquake, volcanic eruption, or landslide. The waves can travel across entire oceans before reaching land. This is lava. This is magma. What's the difference? Magma is molten rock that remains beneath the Earth's surface. It contains molten minerals, gases, and crystals deep inside the planet. Lava is magma that is erupted onto the Earth's surface through a volcano or crack in the ground. Once exposed, it begins cooling and hardening into solid rock.
