Linear (Seif) Dune

long, narrow sand dunes that form in ridges that are roughly parallel, or side by side. A linear dune is the most common type of sand dune and is also known as a seif dune. Linear dunes are shaped by winds blowing in two directions.

parabolic (blowout) dunes

U-shaped dunes with an open end facing upwind

transverse dune

A relatively straight, elongate dune oriented perpendicular to the wind.

Barchan dune

A solitary sand dune shaped like a crescent with its tips pointing downwind.

A, B, D, F

Asteroids commonly A. Are not spherical because they are too small B. Have no craters C. Are made of water ice D. Orbit closer to the Sun than Earth

A. Are not spherical because they are too small

What is the most common rock type in the DARK regions of the moon (aka the lunar maria)? A. Basalt B. Peridotite C. Breccia made from feldspar D. Volcanic glass E. Sandstone

A. Basalt

Which of the following mineral resources are concentrated through weathering and/or groundwater processes? A. Gold B. Chrome C. Platinum D. Beryl

A. Gold

The volume of water ice found in the gas giants (Jupiter, Saturn, Uranus, Neptune) is greater than that of the inner planets (Mercury, Venus, Earth, Mars) because: A. There was more matter farther from the Sun B. The solar wind sucked all the water molecules toward the Sun C. Water ice was not stable close to the Sun where the inner planets orbit D. Drought associated with el Nino

C. Water ice was not stable close to the Sun where the inner planets orbit

_______ are named such because they contain solar energy preserved from past geologic ages. A. solar deposits B. pegmatite deposits. C. fossil fuels D. hydrothermal deposits

C. fossil fuels

star dunes

Dunes that are isolated hills of sand that exhibit a complex, star like form. Develop where wind patterns are changing.

Utah's Bingham Copper mine (Kennecott Copper run by Rio Tinto) is a A. contact metamorphism deposit B. pegmatite deposit. C. placer deposit. D. banded iron formation. E. hydrothermal ore deposit.

E. hydrothermal ore deposit.

Because the earth gets hotter as we dig deeper (the geothermal gradient), geothermal energy is readily available in all areas of the continents. True False
