Deserts are defined by the lack of precipitation, and in fact, Antarctica is also a desert - so we can reject the first and last option since they're not typical of Antarctica.
most deserts are characterized by drastic differences in temperatures: so the best answer is: c. a huge difference between minimum and maximum daily temperatures
I don’t know if anyone will know the answer to this one
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.
Answer: (b) Planet orbit shown as a moderately-flattened ellipse slightly wider than the others with the Sun at precise center of the ellipse. Minor axis is the same as other ellipses.
Explanation:
According to the first Kepler Law of Planetary motion, the orbit of a planet around the Sun, is in the form of an ellipse <u>with the Sun at one of the two foci of that ellipse</u>. This is also valid for any mass orbiting another mass greater than the first one in the space.
In this context, the ellipse is a conic, whose eccentricity is between 0 and 1. So, when its value is 0 we are talking about a circular orbit and when it is 1, a parabolic orbit.
That is, the nearer to the value of 1 (without reaching 1) the eccentricity of the orbit is, the more elliptical it will be.
In this sense, the only option that is incorrect is:
(b) Planet orbit shown as a moderately-flattened ellipse slightly wider than the others <u>with the Sun at precise center of the ellipse</u>. Minor axis is the same as other ellipses.
This statement contradicts Kepler's first law, because the Sun is <u>at one of the two foci of that ellipse</u>. The only way in which the Sun can be at the very center of the orbit is when we talk about a circular orbit. Since a circumference is a especial case of an elipse with eccentricity zero and we get only the center instead of the two foci.
Answer:
C. San Francisco
Explanation:
As the nearby San Andreas, and Hayward faults are responsible for much of tectonic activity i this region. Hence it is more likely that places located close to this would get a Tsunami generated by displacement of earth's floor due to earthquakes. Also many islands and bays that are constructed earlier are also disturbed time to time by this.
