The basalts of the ocean floors are created at the mid-ocean ridges and moves away from these ridges as new crust is created. thus as sea floor spreading occurs the older rock gets pushed away from the ridge towards the continents and the younger rock comes up beside the ridge.
good example is the Atlantic Ocean

What are the two types of crust that makes up the continents and ocean?
The two types of crust that make up the Earth's surface are continental crust and oceanic crust. Continental crust is thicker, less dense, and usually older than oceanic crust. Oceanic crust is thinner, more dense, and typically younger due to the process of seafloor spreading.
How do oceanic and continental crust differ?
Oceanic crust is typically thinner, denser, and younger than continental crust. It is primarily composed of basaltic rocks and forms the ocean floor, while continental crust is thicker, less dense, and contains a wider variety of rock types, including granitic rocks. Continental crust forms the continents and is older than oceanic crust.
What is continental and oceanic crust?
Continental crust is the thicker, less dense, and older type of crust found beneath continents, primarily composed of granite and sedimentary rock. Oceanic crust is the thinner, more dense, and younger type of crust located beneath oceans, primarily composed of basalt. The boundary between continental and oceanic crust is known as the continental-oceanic crust boundary.
Where does the oceanic crust begin?
The oceanic crust begins at the Mid-Ocean Ridge, where tectonic plates are moving apart, allowing magma to rise and solidify, forming new crust. This process of seafloor spreading creates the youngest oceanic crust at the ridge and older crust farther away from it.
Compared to the oceanic crust the continental crust is?
Thicker, less dense, and older than oceanic crust. It primarily consists of granitic rock, is less abundant, and makes up the continents' landmasses. Continental crust also tends to have higher elevations and is more likely to contain mineral resources.
What is older the oceanic crust or the continental crust?
Continental crust is far older than oceanic crust.

What crust is older in years the continental or the oceanic?
Continental crust is far older than oceanic crust.
What is older the continents or the ocean floor?
On average, continents are older than ocean basins. Due to the action of plate tectonics, ocean crust is being formed and destroyed continuously. The oldest oceanic crust is about 200 million years old, whereas continents, which are less dense than oceanic crust and tend not to be subducted into the mantle, can be more than 3,000 million years old in places.
How do oceanic and continental crust differ?
Oceanic crust is typically thinner, denser, and younger than continental crust. It is primarily composed of basaltic rocks and forms the ocean floor, while continental crust is thicker, less dense, and contains a wider variety of rock types, including granitic rocks. Continental crust forms the continents and is older than oceanic crust.
What evidence can prove that the ocean floor was moving?
Oceanic crust that was farther away from a mid-ocean ridge was older that crust closer to the ridge
What evidence proved the ocean floor was moving?
oceanic crust that was farther away from a mid-ocean ridge was older than crust closer to the ridge
Is ocean crust or landform crust yonger?
Ocean crust is younger than landform crust. Oceanic crust is constantly being created at mid-ocean ridges through volcanic activity, making it much younger in comparison to the older landform crust found on continents.
Is oceanic crust near the mid-ocean ridge older thean oceanic crust farther away from the ridge?
Its oceanic crust
How do the ages of the rocks making up continents and those making up the ocean bottom differ?
Continental crust is normally much older than oceanic crust.

Is oceanic crust older than continental crust?
