luda_lava [24]
Harriet Beecher Stowe's novel Uncle Tom's Cabin was a book that worked to expose northerners to the evils of slavery. Harriet Beecher Stowe sought to write a book that would expose the horrors of slavery and to expose the injustices that were taking place in the American South that Northerners might not have been fully informed about at the time. The book was certainly not hailed as a marvelous work in the South and was instead decried and bashed because it sought to expose the practices employed in the South's use of slave labor.

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.
