Both.
While most of the landmass of Earth is made of igneous and metamorphic rocks, most of the rocks that we can actually see (i.e. those on the surface) are sedimentary. Sedimentary rocks are formed from deposition by forces like rivers, waves and glaciers. Sediment, however, comes from eroded material. The same forces that deposit material also erode material. Most sand in deserts and on beaches is made by silicon oxide, otherwise known as quartz. Quartz is an extremely common mineral in igneous (volcanic) rocks. The sand comes from eroded igneous rocks, mostly granite. Quartz happens to be more resistant to erosion than other minerals in granite, like feldspar and mica which erodes to clay-like substances.
If you're talking about the landforms themselves, then it's still both. Landforms are usually categorised as being erosional or depositional in origin.

Are horns caused by deposition?
yes. horns are caused by deposition, and not by erosion. two or more glaciers surround land pushing it up into a sharp point.
What is the usual order by which a land form is changed?
weathering, erosion, deposition
Is a drumlin caused by erosion?
A drumlin is a land-form from glacial deposition, which was once eroded. It is formed both by erosion and deposition. A drumlin is formed when moraine deposited by a retreating glacier is subsequently reshaped by the returning glacier the following year or after the glacial interval with caused the glacier to retreat in the first place.
How do landform evolve?
There are many different ways that a land form evolve. These land forms can evolve by erosion or deposition for example.
How erosion and deposition are related?
Erosion and deposition have an amazingly close relationship. Erosion and depositions are the exact opposites of each other in terms of land.
What part of a cycle shapes and reshapes land?
answer is deposition and erosion~
Describe the two major processes by which a river changes the land?
Deposition and erosion are two major processes by which a river changes the land. Erosion is the combination of weathering and deposition in which the water loosens and moves the land to another place.
How does weathering erosion and deposition affect where people live?
no
What type of glaciers are there and how do they erode the land?
glacial deposition and glacial erosion
Explain the difference between erosion and deposition?
Glacial erosion is the process by which a glacial flows over the land, picking up rocks. Glacial deposition is the process by which a glacier gathers a huge amount of rock and soil as it Erodes the land in the path
How do erosion and deposition work together to change the shape of land?
erosion moves, and depostion is dropping off sediments
What land form change is most easily controlled by human A volcanic deposition of lava B coastal erosion C surface movement in earthquakes D erosion of desert sand by wind?
C
