People in the oil-rich country of Dubai must adapt to a lack of natural
freshwater. How does this contribute to carbon emissions and global
warming?
A. Oil is used for many purposes that water fulfills in other countries.
B. Fossil fuels are burned for energy to remove salt from seawater.
C. The sand gets too hot because there are no rivers or lakes to cool
it.
D. Cars are used to drive many miles in search of something to drink.
Answer:
D
Explanation:
4. Search for 39 05 52.46N 84 30 56.16E and zoom out to an eye altitude of ~9,000 meters. The large-scale structures in this sedimentary environment are asymmetrical ripples (known as dunes at this size). Zoom in and out and examine the sedimentary environment. What type of sedimentary environment is this
Answer:
Eolian sedimentary environment
Explanation:
Winds can transport many different-sized particles of material from the ground through the process of erosion. These particles might travel many kilometers until they deposit somewhere. Regions with scarce vegetation have too much dust and grain-sized particles that move and crush each other, increasing erosion. This process is known as eolic erosion.
The most prominent accumulations of wind deposits are the dunes. However, there are other smaller accumulations such as the ripples and other larger ones called Draas. Their main differences are in addition to size, is the wavelength between them.
Dunes are winds deposits, formations that are, in general, typical of deserts. Dunes are orientated according to the direction and speed of winds, to the presence of loose material, and vegetation. Strong winds transport material until it collides with an object or obstacle where it is deposited, originating a new dune.
Dunes are very dynamic formations that are constantly being remodeled by the direction and strength of the winds. Dunes always have a soft slope and a sharp one. The soft slope is directed to the area or region where the wind is coming from and is the product of the wind erosion on the same dune. The opposite sharp slope is protected from the wind and is the deposition place, where the wind losses strength and the carrying material falls, depositing in this side of the dune.
Sinkiang is a desert in China. Placing yourself at 39 05 52.46N 84 30 56.16E lets you appreciate the duned shape of the ground. By zooming in and out, you can notice the soft and sharp slopes that are forming each of the dunes and the distance between them.
In the Layers panel, turn on Borders and Labels and also Gallery > Volcanoes, then double-click on the Problem 7 placemark. Divergent boundaries often begin as triple junctions composed of three rift "arms" at ~120° apart (which may or may not evolve into divergent boundaries). Knowing that rifts (red lines) generally open perpendicular to the rift (or sub-parallel to the light blue transform faults), which of the statements below about this area is incorrect?
a. the NW-trending Red Sea is a linear sea that is opening in a NE-SW direction
b. the ENE-trending Gulf of Aden is a linear sea that is opening in a NNE-SSW direction
c. the volcanoes in Africa define a narrow linear rift that is opening in a NW-SE direction
d. the volcanoes in Africa define a volcanic arc related to subduction off Africa's east coast
Answer:
d. the volcanoes in Africa define a volcanic arc related to subduction off Africa's east coast
Explanation:
Many crust plates move over the mantle. These plates are limited by three types of ridges or borders that differ in the movement they produce.
Boundaries types: Divergent, Convergent, and Transforming.
Divergent boundary: Occurs along with an underwater mountain range, known as the mid-oceanic ridge or divergent ridge. New crust is created by the molten materials rising from the mantle. The two plates at each side of the rift separate, and the stream of hot material creates a new seabed between them. It occurs an expansion of the sea bottom, which separates the plates. The divergence direction is transversal to the rift orientation. Old plates get separated, and the new crust instantaneously gets formed. The emerging mantle occupies the space left by the separation of the two plates.
a. the NW-trending Red Sea is a linear sea that is opening in a NE-SW direction. CORRECT → The diverging direction is perpendicular to the rift orientation.
b. the ENE-trending Gulf of Aden is a linear sea that is opening in a NNE-SSW direction. CORRECT
c. the volcanoes in Africa define a narrow linear rift that is opening in a NW-SE direction. CORRECT.
d. the volcanoes in Africa define a volcanic arc related to subduction off Africa's east coast ⇒ INCORRECT. The collision between plates creates volcanic arches and continental arches. This process belongs to the convergent boundaries, in which two oceanic plates collide, or one oceanic plate crushes with a continental one.
