Global Maps of Dryness Help Prepare for Water Use Around Globe

The video explains gravity's role in Earth's orbit and water tracking through the GRACE mission. It highlights how advanced models forecast water availability, aiding in drought and flood preparation. Case studies from Okavango, Australia, and Europe illustrate the impact of climate events on water resources. NASA's global monitoring helps manage water extremes.

What is one of the primary functions of gravity as mentioned in the video?

• To keep Earth orbiting around the sun

• To keep the moon orbiting around Mars

• To prevent satellites from launching

• To make water evaporate faster

What is the main purpose of the GRACE mission?

• To study the sun's surface

• To explore outer space

• To track water movement on Earth

• To measure air pollution

How do advanced computer models help in water forecasting?

• By predicting the weather

• By distinguishing water in different soil layers

• By measuring air temperature

• By tracking animal migration

What is a key factor in predicting flash floods?

• The height of mountains

• The speed of wind

• The level of surface soil moisture

• The amount of sunlight

How did the GRACE mission help during the drought in Australia?

• By increasing rainfall

• By cooling down temperatures

• By drying up vegetation

• By monitoring changes in water layers
