From the oceans
The first step in the water cycle is evaporation, where water from bodies of water like oceans and lakes turns into water vapor and rises into the atmosphere.
evaporate
Nerve agents are highly toxic in all forms whether solid, liquid, or vapor
Ice, liquid, and vapor
it measures the water vapor content of air or the humidity.
Scientists believe that Earth's oceans formed about 4 billion years ago through a process called "outgassing," where water vapor and other gases were released from the Earth's interior through volcanic activity. As the Earth cooled, the water vapor condensed and fell as rain, filling the low-lying areas to create the oceans.

Scientists collect data about water vapor in the air to understand the moisture content of the atmosphere, which is crucial for studying weather patterns and climate change. Water vapor plays a key role in the Earth's energy balance, influencing temperature, cloud formation, and precipitation. Monitoring water vapor helps scientists improve weather forecasting models and predict future climate trends.
Clouds, fog.
Scientists studying the Earth's climate changes have found that increased temperatures lead to increases in water vapor in the atmosphere, which adds to global warming. This means that increases in temperature and water vapor feed each other.
No, water vapor is the most abundant gas in the Earth's atmosphere, not liquid water. Water vapor makes up around 1% of the atmosphere.
Yes, scientists believe that a significant portion of Earth's early ocean water was formed from the condensation of water vapor in the primitive atmosphere, as well as from water-rich materials like comets and asteroids that collided with the planet during its formation.
Yes, scientists believe that most of Earth's water came from volcanic activity releasing gases like water vapor, which later condensed and fell as rain, filling up the low-lying areas to form the oceans. Cooling of the Earth's surface also played a role in the formation of oceans by allowing the water to accumulate in depressions on the Earth's crust.
Frozen water vapor that falls to earth as flakes is called snow.
There is no first in a cycle but, most are comfortable thinking ice melts to water, water evaporates to vapor, vapor condenses and fall to earth as rain to snow.
The water vapor concentration constantly fluctuates.
The rain cycle, Water vapor rises, cools , condenses into drops, and falls back to earth.
