Glaciers and Their Impact on Earth

Mikaela, a NASA geologist, studies glaciers using satellites to understand their impact on Earth's landscape. She observes how glaciers move and change, affecting rivers and transporting rocks and minerals. By comparing satellite images over time, she documents the shrinking of glaciers and shares her findings on social media to highlight the effects of climate change.

What is the primary role of a geologist?

• To study the stars and planets

• To explore the ocean depths

• To study the Earth and its natural resources

• To design spacecraft

What is a glacier?

• A large body of water

• A giant thick piece of ice covering land

• A type of rock formation

• A small ice cube

How do glaciers affect the Earth's surface?

• They create deserts

• They form mountains, valleys, and lakes

• They cause earthquakes

• They increase volcanic activity

What tool does Mikaela use to study glaciers from space?

• A microscope

• A satellite

• A drone

• A telescope

What changes has Mikaela observed in the glaciers on Mount Rainier?

• The glaciers have disappeared completely

• The glaciers have shrunk and moved down the mountain

• The glaciers have remained the same

• The glaciers have grown larger

What effect does melting glacier ice have on rivers?

• It has no effect on rivers

• It dries up the rivers

• It widens rivers as water flows down

• It makes rivers narrower

How does Mikaela share her findings about glaciers?

• By giving public speeches

• By posting on social media with the hashtag #shrinkingglacier

• By writing books

• Through television broadcasts

What might happen if Earth's temperature continues to rise?

• Glaciers will stop melting

• Glaciers will melt faster, changing the landscape

• Glaciers will freeze more

• Glaciers will remain unchanged

What is the main purpose of Mikaela's report?

• To describe the history of Mount Rainier

• To entertain readers

• To explain how Earth's landscape might change due to glacier melting

• To predict future weather patterns

What invitation does the video extend to the viewers?

• To explore geology and go on an adventure

• To become astronauts

• To study marine biology

• To visit Mount Rainier
