Science
This process transforms liquid water into a gas or water vapor.
What is evaporation?
This river is the longest in Texas, extending 1,280 miles and running near such cities as Waco and College Station.
What is the Brazos River?
In this process, water is transformed from a gas to a liquid.
What is condensation?
This type of rock slowly dissolves in acidic water forming caves or caverns.
What is limestone?
Areas that are periodically or permanently covered with fresh or salt water.
What is a wetland?
At sea level, water boils at this temperature.
What is 212 degrees Fahrenheit, or 100 degrees Celsius?
This river flows through Texas' capital city?
What is the Colorado River?
This process describes how water moves into the soil surface.
What is infiltration?
These form as a result of geothermal springs, bringing warm or hot water to earth's surface. Many of these are found in Yellowstone National Park.
What are geysers?
A water basin or drainage area which collects precipitation within its topographic boundaries.
What is a watershed?
When water is placed in a tube, this forms as water is pulled slightly higher on the sides of the tube compared to the middle, forming a crescent shape.
What is meniscus?
This river forms a long stretch of the northern border between Texas and Oklahoma.
What is the Red River?
This term describes the movement of water from plant pores into the atmosphere.
What is transpiration?
Many of these naturally bring groundwater to the surface, and are often a primary water source for rivers and streams.
What are springs?
In this process, energy in sunlight is captured by a plant to produce food from carbon dioxide and water, releasing oxygen as a byproduct.
What is photosynthesis?
This term describes how heavy something is compared to its volume.
What is density?
This river stretches from southern Colorado to the Gulf of Mexico extending through three states.
What is the Rio Grande River?
This process occurs when solid water transforms directly into water vapor without becoming a liquid first.
What is sublimation?
This large aquifer underlies portions of eight states, including the Texas Panhandle.
What is the Ogallala Aquifer?
This type of pollution comes from a broad area or wide variety of sources.
What is non-point source pollution?
This property of water explains how some insects are able to remain on the water's surface without falling in.
What is surface tension?
This remote, 90-mile long river located in southwest Texas is considered the most pristine in Texas.
What is the Devils River?
Water that flows off of surfaces into streams and rivers, ponds, lakes or the ocean.
What is runoff?
In this type of water well, water comes to the surface without being pumped.
What is artesian?
This is caused by excessive nutrients such as nitrogen and phosphorus in a water body. It causes dense growth of aquatic plants and decreases oxygen levels in the water.
What is eutrophication?
