What new discovery did LIDAR reveal about the floods in the Okanagan Valley?

• There were no floods in the valley

• Floods originated from the Pacific Ocean

• Major floods came from Canada

• Floods were caused by volcanic eruptions

What is the significance of the ripple marks found along the Columbia River?

• They are remnants of ancient glaciers

• They are evidence of tectonic shifts

• They show the impact of enormous water flow

• They indicate volcanic activity

How does LIDAR help in predicting future river flooding?

• By measuring current water levels

• By mapping vegetation growth

• By tracking weather changes

• By analyzing historical flood patterns

What is the expected impact of climate change on river flooding in the United States?

• Flooding will only affect coastal areas

• River flooding will intensify

• No change in flooding patterns

• Decrease in flooding events

What does the study of ancient deglaciation processes inform us about?

• Future tectonic activity

• Past volcanic eruptions

• Historical climate patterns

• Expected changes in ice-covered regions

What is the role of LIDAR in geomorphic investigations?

• It tracks animal migration patterns

• It helps in identifying mineral deposits

• It provides a detailed view of Earth's surface

• It measures atmospheric pressure
