Aquifer Conservation and Features

The video explores the Lady Bird Johnson Wildflower Center's role in promoting native plants and its location over the Edwards Aquifer. It delves into the geological history of Central Texas, focusing on limestone formation and its role in water recharge. The video explains karstic limestone's unique properties, aquifer dynamics, and the environmental significance of the Edwards Aquifer, emphasizing conservation efforts to maintain water quality.

What was the primary purpose of the Lady Bird Johnson Wildflower Center?

• To study dinosaur fossils

• To promote the use of native plants

• To develop new plant species

• To create a wildlife sanctuary

How did limestone form in Central Texas?

• From volcanic activity

• From the accumulation of shells in a shallow sea

• From desert sand deposits

• From glacial movements

What is a key feature of karstic limestone?

• It is formed from volcanic lava

• It has characteristic holes like Swiss cheese

• It is impermeable

• It is a type of igneous rock

What happens when water enters the aquifer?

• It turns into steam

• It forms a new rock layer

• It becomes part of the groundwater system

• It evaporates immediately

What are stalactites and where are they found?

• They are rock formations found on cave floors

• They are plant roots found in soil

• They are mineral deposits found on cave ceilings

• They are water channels found in rivers

How does water travel from the surface to the aquifer?

• Through evaporation

• Through karst features like sinkholes and caves

• Through direct absorption by plants

• Through man-made channels

Why is the Edwards Aquifer important for endangered species?

• It is a breeding ground

• It offers a migration path

• It is a source of food

• It provides a unique habitat

What did the dye tracing study reveal about water movement in the aquifer?

• Water moves very slowly

• Water evaporates before reaching the springs

• Water moves quickly through the aquifer

• Water does not move at all

Why is the Edwards Aquifer not a good filter for water?

• It is too deep underground

• It has a network of holes and cracks

• It is covered by a thick layer of soil

• It is made of solid rock

What can individuals do to help keep the aquifer clean?

• Use more plastic products

• Plant non-native species

• Increase water usage

• Pick up litter and clean up after pets
