What else can I help you with?
Why are upper winds stronger than surface wind?
Surface winds are slowed by friction caused by topography as well as the built environment.
Is it true or false that winds are caused by differences in air pressure?
yes this is true. this is also why you can get stronger winds if the pressure gradient in the atmospshere is greater
How are transverse dunes different from barchan dunes?
Barchan dunes are solitary crescent dunes formed on a flat, hard ground with limited supplies of sand and vegetation. Transverse dunes are a series of long ridges that are found in areas that have a lot of sand but sparse vegetation.
What are BWh climates caused by. Subtropical Highs. Trade Winds. Westerlies. Warm Ocean Currents. None of these?
Subtropical Highs
What keeps sand dunes in place?
Plants can help stabilize sand dunes and prevent them from moving.
Is Barchan dunes are created by strong onshore winds?
Barchan dunes are crescent-shaped dunes that are formed by winds blowing consistently in one direction. These winds are typically strong and blow a constant supply of sand, causing the dunes to migrate downwind.
What erosional force can make sand dunes?
The force of winds shapes sand dunes.
What is a hill of sand broken by winds?
Sand dunes
Was sand dunes formed by erosion or deposition?
sand dunes are caused by deposition . some people think its caused by erosion , but erosion is the braking down of land formations. sand dunes are caused by strong winds pushing sand grains into piles.
What causes deserts dunes?
Wind moving sand causes dunes, both in the desert and at the beach.
Why are sand dunes formed at the northern end of beaches on the east coast of Australia?
Because the Southerly winds shape the dunes. The dunes are primarily formed over winter when Southerlies are prevalent.
What are the strong winds that keep moving the sand dunes in a desert from place to place?
The strong winds that move sand dunes in a desert are often referred to as "trade winds" or "desert winds." These winds are typically dry and can reach high speeds, effectively lifting and transporting sand particles across the landscape. The constant movement and shifting of these winds cause the dunes to change shape and location over time. Additionally, local wind patterns, influenced by topography and temperature variations, also contribute to the dynamics of sand movement.
Photographs of the surface of Mars reveal the presence of sand dunes that shift over time. These dunes demonstrate the presence of what phenomenon on Mars?
winds
When winds blow steadily from the west sand dunes will be steepest on the?
east side.
Why does sandstorms occur?
This wind is usually caused by convection currents (which are created by intense heating of the ground), and is usually strong enough to move entire sand dunes. Air is unstable when heated, and this instability in the air will cause the mixture of higher winds in the troposphere with winds in the lower atmosphere, producing strong surface winds.
What is caused by a wave depositor?
sand dunes
What causes sediment that is picked up by the wind to fall to the ground?
This wind is usually caused by convection currents and is usually strong enough to move entire sand dunes. Air is unstable when heated, and this instability in the air will cause the mixture of higher winds in the troposphere with winds in the lower atmosphere, producing strong surface winds.
