Waves and currents erode away the rocks of the shore

Landforms: Sea Caves, Sea Arches, Sea Stacks, Fjords, Sea Cliff, Beaches

When a continental tectonic plate collides with another plate it is compressed and mountains form.

This takes Millions of years.

Examples: Andes, Rocky, Himalayan Mountains

When a river or lake flood the surrounding area.

Can cause major erosion of landforms

Moving water Erodes away the rocks it passes.

Landforms: Ox Bow Lakes, Valleys, Delta

Volcanoes under the ocean erupt and create new crust.

Slowly this crust builds up until it makes an island.

Over Thousands of years the islands slowly erode back into the ocean.

When a celestial object falls and crashes into Earth's Surface.

Creates an impact crater, sends a dust cloud into the sky that can block the sunlight causing plants and animals to die.

As the Ice Flows forward it scrapes away and smooths the land.

As the Ice Melts it forms Rivers and Lakes

Rivers flow faster as the ice melts

Glaciers melt and form lakes in a low spot
