What are the similarities in the way a barchan forms and the way a hooked spit forms?
choli [55]

Answer:

The similarities in the way barchan and hooked spit forms are:

First, they are formed from sediment or sand movement.

Second, this movement makes them have a peculiar curved form that provides them their major characteristic.

Explanation:

First of all, barchans are sand formations that are created after the accumulation of sand in a place is moved by the wind and provides them a curved form. However, they exist only out of the sea.

Second, hooked spits are formations that happen after sea movement displaces the sediment to create a curved structure that can only exist in the sea. These formations affect the strength and direction of the waves in the sea due to their curved form.
