This is the definition of a "barrier spit". (A tombolo is a sandbar that connects the mainland to an island, forming a permanent or temporary isthmus, and the island can be known as a "tied island".)
They are alike because both are just alike..
How is is fifteen and flatter alike
The only way they are both alike as if they a equilateral.
The answer depends on what they are meant to be alike and different from!
They're known as spits, if they are merely pieces of land unattached to a second island. However, when they become attached, they form a tombolo.
Sand spits form when elongated sandbars remain in place due to wave action along a shoreline. The spit can remain attached to the shore as an isthmus, or a bar can be separated to form a barrier island. Tombolos can create the same form but in the opposite manner. An island near the shore accumulates sandbars in the separating strait, and can become a "tied island" when the tombolo creates a permanent land bridge.
a tombolo is a spit that joins the mainland to an island
What is a Tombolo?
Tombolo's are ridges of sand and shingle which join the mainland to an island. Tombolo's are created through the process of longshore drift. Where there is a change in the shape of the land, a spit forms in the shallow / sheltered water. A tombolo is formed where the spit continues to grow until it reaches an island, forming a link with the mainland

When you have longshore currents that transport the sand along a beach, they can create a spit where there is a projection along the coast. Spits develop from a wave train that is oblique to the shore causeing the sand to be deposited longitudinally projecting from the protruding point on the shore. They are attached to the shore at one end. Trombolos can occur when currents create a bar from the beach out of a large quantity of oceanic sediment called a stack. A trombolo is somewhat like a large ripple created from the stack accumulation. The are alike in a general sense of oceanic deposits but are very different in that the currents are oblique (tombolo) and more perpindicular (spit).

Mark Spits is alive!
spits are the processes of longshore drift, this is where the waves deposit sand down a beach according to prevailing wind, this happens gradually and this sand can stretch around the headlandand out from the shore, the are behind the spit will become a salt marsh as it will get less water, these spits can then extend and join up two parts of the headland (a bar) or a headlant ot an island (a tombolo).
there are 550 types of spits
