The dunes space hills developed by grains of sand held together by the activity of wind or water. Over time, together sand dunes have tendency to migrate in the exact same direction as the wind blows.

You are watching: Over time sand dunes tend to migrate

They have a larger side the is eroded (windward) and also a smaller, steeper side (leeward) where deposition that eroded product occurs. V this mechanism of erosion and also deposition the dunes are considered highly dynamic, "moving" end time.

3.0 m/s236.3°

Step-by-step explanation:

The wind speed have the right to be uncovered using the legislation of Cosines. It will be the unknown next of a triangle through sides 6 and 5 and included angle 30°.

s^2 = 6^2 +5^2 -2·6·5·cos(30°) ≈ 9.038476

s ≈ √9.038476 ≈ 3.0064 . . . . M/s

The direction the the wind have the right to be found from the law of Sines, i beg your pardon tells united state the relationship of the internal angle A to velocity vector a is ...

sin(A)/a = sin(30°)/3.0064

A = arcsin(5/3.0064·sin(30°) ≈ 56.26°

To uncover the wanted angle, us must add 180° come this value.

The wind is blow 3.0 m/s in direction 236.3°.

Explanation:

From the land to the ocean

Explanation:

Hi, an initial of all, you can"t say that the wind literally comes or goes to the moon. For this reason the real concern is: that goes indigenous land come the ocean or the otherway?

The waves type when lock wind moves from the ocean to the shore. Being the said and also looking the there isnt any kind of waves in the photo you can say the the wind blows from the land to the ocean.

Step-by-step explanation:

Given

Initially aircraft is flying at the rate of

to the

north of east

Now wind began Blowing and plane started moving towards eastern with rate

suppose

is the rate of wind

So,

So magnitude of wind is

Explanation:

When a hurricane intensifies and the wind speed increases, an eye starts to kind in the center of the storm. This normally occurs once the winds reach around 80 mph. Almost always the eye is circular when viewed indigenous above, and measures around 20 come 40 miles in diameter. It looks cylindrical in a cross section of the storm, and extends with the center of the storm choose a chimney. The air over the storm sinks through the facility of the eye.

Hurricanes are formed from centers of low atmospheric pressure in heat waters around which strong air currents begin to circulate.

When ocean water heats up, the waiting rises and also swirls to fill the low push that this creates.

This causes the air come be suck in and also up, which reinforces the low press in the center.

Thus, when the wind speed boosts to 128 km / h, a sort of "vacuum" is created that meteorologists speak to "eye", because it has an practically circular shape.

The airflow will certainly be northwest.

Explanation:

A heat moist waiting mass moves northwest over an arid and cool area.

The winds normally blow from eastern to the west rather than blowing from the north to the south in the northern and the southerly hemispheres.

Explanation:

The factor for the punch of the wind indigenous the east to the west rather than indigenous the phibìc to the south in both the hemispheres which room the northern and also the southern hemispheres are since it wake up in irradiate of the truth that Earth"s rotation around it"s own axis create what is well-known as the Coriolis effect.

The Coriolis affect makes wind frameworks revolve counter-clockwise in the north Hemisphere and clockwise in the southern Hemisphere.

west to eastern I go this in course today and also is relates

it is a

At wind speeds above 1000 centimeters per 2nd (cm/sec), significant sand-moving events start to occur. Wind speeds listed below 1000 cm/sec deposit sand and wind speeds over 1000 cm/sec move sand to new locations. The cyclic nature the wind and also moving sand determines the shape and also location of big dunes. In ~ a check site, the prevailing direction the the wind go not change noticeably. However, the velocity go change. Sixty wind speed readings gave an mean velocity the x = 1075 cm/sec. Based upon long-term experience, σ have the right to be suspect to be 270 cm/sec. Uncover a 95% trust interval for the populace mean wind speed at this site.
