Continents and oceans are formed through a process called plate tectonics. This process involves the movement of the Earth's lithosphere, which is made up of large plates that float on the semi-fluid asthenosphere below.
Continents are formed when two plates collide, causing the crust to buckle and fold, creating mountain ranges and landmasses. Oceans are formed when plates move apart, creating gaps that are filled with water from the Earth's mantle.
Over millions of years, the movement of these plates has shaped the Earth's surface, creating the continents and oceans that we see today. The formation of continents and oceans is an ongoing process, with new landmasses being created through volcanic activity and erosion constantly reshaping coastlines.

Formation of Continents:
- Continental Crust Formation: The Earth's mantle melted to form magma, which rose to the surface and crystallized into igneous rocks. These rocks were denser than the surrounding rocks and sank beneath the ocean crust.
- Collision and Accretion: Over time, tectonic plates carrying these igneous rocks collided with each other, forming mountain ranges and eventually continents.
- Continental Drift: The continents continued to move, driven by plate tectonics. Collisions and rifting created and separated landmasses, giving rise to the present-day continents.
Formation of Oceans:
- Early Ocean Formation: As the Earth cooled, water vapor in the atmosphere condensed and formed oceans. This process is thought to have occurred within the first billion years of Earth's history.
- Plate Formation: The Earth's crust began to break into rigid plates. These plates moved and collided, creating subduction zones where one plate slipped beneath another.
- Seafloor Spreading: At mid-ocean ridges, new oceanic crust is created as magma rises from the mantle and solidifies. This process pushes the ocean floor apart and expands the oceans.
- Subduction and Recycling: At subduction zones, oceanic crust is recycled back into the mantle. This process helps to maintain the balance of crustal materials and the size of the oceans.
