13 Questions
What is the main reason Hawai'i is a great place to observe lithospheric changes?
It experiences both volcanoes and earthquakes
What causes earthquakes to occur?
Stress buildup in the Earth's crust
What is a fault?
A crack in the Earth's crust caused by stress in surrounding rocks
How do volcanoes and earthquakes contribute to landscape transformation?
They can radically transform the landscape in a short time
What causes stress buildup in the Earth's crust?
Pieces of the Earth pushing and grinding past each other
What gives people a small glimpse of interesting features of the Earth?
Snorkeling
How do people benefit from identifying lithospheric features both underwater and on land?
It provides clues about how the Earth's crust changes
What causes tsunamis?
Earthquakes, landslides, or volcanic eruptions
How are volcanoes formed?
Lithosphere pulling apart, crust being forced back into the mantle, or mantle plumes rising to the surface
What are hot spots like Yellowstone National Park and the Hawai'ian islands caused by?
Mantle plumes rising to the surface
How do rocks cause earthquakes?
Pressure changes due to new sediment deposits
What do seismologists study to understand the Earth's interior?
Earthquake waves
What do lava types from volcanoes provide clues about?
The Earth's interior
Study Notes
- Rocks store energy and cause earthquakes when the pressure changes due to new sediment deposits
- Seismologists study earthquake waves to understand the Earth's interior, revealing the five layers: solid inner core, liquid outer core, liquid mantle, taffy-like upper layer, and outer crust
- Tsunamis, or tidal waves, can be caused by earthquakes, landslides, or volcanic eruptions
- Tsunamis travel fast in the open ocean but slow down near the shoreline, causing destruction and sometimes multiple waves
- Volcanoes form in three ways: lithosphere pulling apart, crust being forced back into the mantle, or mantle plumes rising to the surface
- Hot spots, such as Yellowstone National Park and the Hawai'ian islands, are areas of volcanic activity caused by mantle plumes
- Lava types from volcanoes provide clues about the Earth's interior
- Weathering and deposition, processes on the surface of Hawai'i, are caused by natural agents like wind, water, or sun
- The Hawai'ian islands were formed by a mantle plume depositing volcanic lava over a long period, with the Big Island being the most active volcanic area currently
- A new island, Lo'ihi, is forming off the Big Island's southeast coast but is currently underwater and will take a long time to reach the surface.
