Earth 's Layered Structure
Earth 's interior is composted of distinct layers with varying physical and chemical performanties. These layers drive thee tectonic movements andd thermal energy that build landforms. The main layers are thee cruct, mantle, outer core, and inner core.
TheCruct
Te kruche is Earth 's outermost solid shell, ranging frem about 5- 70 km in gruxs. It is divided into two type: continental cruct, which is thicker and less dense (mostly granite), and oceanic cruct, which is thinner anddenser (basalt). All landforms we see are part of thee crust, whih is broken into tectonik plates. The composition and structure of thee cross direcTY influence thee type type of landforms thathan develoop.

Geological Processes That Sculpt the Surface
Landforms are built and destrucyed by a handful of fundamentamental geological processes. These processes operate over million of years, constantly reshaping thee landscape.
Plate Tectonics
Plate tectonics is the engine behind many of Earth's largest landforms. At convergent boundaries, plates collide. When two continental plates meet, they crumple and thicken, forming mountain ranges such as the Himalayas. When an oceanic plate subducts beneath a continental plate, it creates volcanic arcs and ocean trenches. Divergent boundaries, such as the Mid-Atlantic Ridge, produce rift valleys and new oceanic crust. Transform boundaries, like the San Andreas Fault, generate linear valleys and fault scarps. The continuous motion of plates also triggers earthquakes and volcanic eruptions, which further modify the landscape.
Wulkanizm
Volcanic activity events when magma from the mantle rises through gh thee cruct. The resucting landforms included shield wulcan (broad, gently sloping cones like those in hawaji), stratovolcautoes (steep, explosive peaks like Mount Fuji), and wulcan plateaus (extensive lava flows). Volcanic eritions also create new land - such as thee island of Surtsey, whch emerged from thee Atlantic oceain 1963.

Erosion andWeathering
Erosion is te removal and transport of surface material at, wind, ice, or gravity. Weathering breaks rock into smaller piece distrang physiar or chemical means. Together, these processes carve valleys, shape coastrides, and wear down mountains.

Sedimentation
Eroded material is transportowane and deposite eldere, creating new landforms. Rivers deposit sediment in floodprews andd deltas. Wind builds sand dunes. Lakes and oceans acculate layers of sediment that contee sedimentary rock. Deposition can also occur slowly, as in the formation of alluvial fans at mountain bases. These sedimentary landforms are often flat and inventie, supporting aid dene spomenations.
Major Landform Types andTheir Formation
Landforms are e categorized by their shape and elevation relative te otherrounding terrain. Each type results from specific combinations of tectonic activity, wulkan action, erosion, and deposition.

Góry are elevated landforms rising prominently above arounding terrain. They are primaryly formed by tectonic compression at convergent plate boundaries. Fold mounts (e.g., the Appalachians), fault- block mounts (e.g., the Sierra Nevada), and wulkan mountail (e.g., Mount Rainer) convergent processes (e. the Appalachians), fault- block mounche locame by fordinforcing air to rise and cool, creating contritation on ward slopes raid shaun bladond.

Plateaus are flate- topped elevated areas that rise rise abovie adjacent lowlands. They can form when magma pushes up thee crust (plateaus wulkan), when horizontal rock layers are uplofted, or wheren erosion removes arounding material, leaving a resistant cap (mesas and buttes).

Valleys are elongated low area between hills or mounders. River valleys are V- shaped, formed by downcuting streams. Glacial valleys are U- shaped, formed by the scouring action of moving ice.

Wind
In dry, sparsely vegetate areas, wind transports sand andd duss, creating dune fields andloess deposits. Wind erosion can produce ventilfacts (rocks switched by windblow sand) and deflation hollows. Coastal winds also shape sand dunes. While wind is less effective than water, it is a dominant force in deserts and some planetary surfaces.
