Question

Match the geologic feature with its description. 1. seamount underwater volcano that never reaches above sea level 2. syncline underwater volcano whose top is eroded flat by waves 3. hot spring on rolling hills, this a dip between hills 4. volcanic neck break between rocks where a hanging wall rises relative to a footwall 5. caldera magma that filled the central vent that remains after the volcano has eroded 6. horst natural hot water on Earth's surface containing many minerals 7. graben a raised footwall block between normal fault creates this 8. crater less than a mile in diameter; looks like a bowl at the top of a volcano 9. guyot over 1 mile in diameter; looks like a bowl over a volcano 10. reverse fault created when a block with hanging walls slips down between normal faults

Answer 1

Answer:

Explanation:

1. Underwater volcano that never reaches above sea level

GUYOT

2. Underwater volcano whose top is eroded flat by waves

SEAMOUNT

3. Hot spring on rolling hills, this a dip between hills

SYNCLINE

4. volcanic neck break between rocks where a hanging wall rises relative to a footwall

REVERSE FAULT

5. Magma that filled the central vent that remains after the volcano has eroded

VOLCANIC NECK

6. Natural hot water on Earth's surface containing many minerals

HOTSPRING

7. A raised footwall block between normal fault creates this

HORST

8. Less than a mile in diameter; looks like a bowl at the top of a volcano

CALDERA

9. Over 1 mile in diameter; looks like a bowl over a volcano

CRATER

10.Created when a block with hanging walls slips down between normal faults

GRABEN

Answer 2

Answer:

1. seamount : underwater volcano that never reaches above sea level

2. syncline : on rolling hills, this a dip between hills

3. hot spring : natural hot water on Earth's surface containing many minerals

4. volcanic neck  : volcanic object created when magma hardens within a vent on an active volcano.

5. caldera : magma that filled the central vent that remains after the volcano has eroded

6. horst : a raised foot wall block between normal fault creates

7. graben : created when a block with hanging walls slips down between normal faults

8. crater : over 1 mile in diameter; looks like a bowl over a volcano

9. guyot : underwater volcano whose top is eroded flat by waves

10. reverse fault :break between rocks where a hanging wall rises relative to a foot wall

Explanation:

• A guyot is seamount that is built above the sea levels.  A horst is transformed when the walls are uplifted and the graben is formed when the wall are downshifted, a crater is a circular depression on the surface, a calendar is feature due to the collapse of the volcano itself.

• A seamount under water volcano that never reaches the surface, and the reverse fault s one side of the fault that moved over the other side of the foot wall.
