Earth Science

Question 0

Folded Mountains

Answer 0

produced by rock layers folding during formation. ex: Himalayas, Alps

Question 1

Orogeny

Answer 1

Natural Mountain Building

Question 2

Fault-block mountains

Answer 2

Tension rather than compression forces. (diverge or slip) ex: Utah, Arizona, New Mexico

Question 3

Dome mountains

Answer 3

When magma pushes up on crust but fails to break through. Like a blister on earth’s surface

Question 4

Upwarped mountains

Answer 4

broad arching of the crust. Formed also by rock thrust upward along high angle faults. ex: black hills South Dakota

Question 5

Volcanic Mountains

Answer 5

built up by successive deposits of volcanic materials

Question 6

Shield volcano

Answer 6

Quiet eruptions. Lava emerges by vent or opening in the crater and flows freely out over the earth’s surface until it cools and hardens in a layer of igneous rock. Ex: Mauna Loa, Hawaii - largest volcano on earth.

Question 7

cinder cone volcanos

Answer 7

explosive eruptions. Lava hurled into the air in a spray of various sized droplets. These pile up to form a small volcano

Question 8

Composite volcanos

Answer 8

built from both lava flows and layers of ash and cinder. EX. Mount Fuji, Mount St. Helens, Mount Vesuvius.

Question 9

anticlines

Answer 9

up-folded sections of folded mountains (crest)

Question 10

synclines

Answer 10

down folded sections of rock (trough)

Question 11

Dip-Slip fault

Answer 11

Movement of plates is vertical and opposite. (one side moves up, one side moves down.)

Question 12

2 types of dip-slip fault

Answer 12

1. normal, footwall up, hang wall down (divergent boundaries)
2. reverse (or thrust), footwall down, hang wall up (convergent boundaries)

Question 13

strike-slip faults (transform fault)

Answer 13

horizontal motion (San Andreas fault is a strike slip)

Question 14

Oblique-slip fault

Answer 14

vertical and horizontal motion.
