Yes, deposition can take place without erosion. Deposition is the process by which sediment is laid down on the Earth's surface. This can happen when the water or wind slows down and can no longer carry the sediment. It can also happen when the water or wind changes direction and deposits the sediment in a new location.

One example of deposition without erosion is when a river slows down as it enters a lake or the ocean. The sediment that the river was carrying will settle to the bottom of the lake or ocean, creating a new layer of sediment.

Another example of deposition without erosion is when wind slows down as it passes over a hill or mountain. The sediment that the wind was carrying will settle to the ground, creating a new layer of sediment.

Deposition can also occur when the Earth's crust moves, such as during earthquakes or volcanic eruptions. When the crust moves, it can create cracks or gaps in the ground, which can fill with sediment.
