What is a long ridge of sediments deposited alongside a river channel called?
the oak ridges
A narrow winding ridge composed of out wash deposited in a tunnel or channel cut into stagnant glacial ice?
An eskers
What forms an esker?
An esker is formed by the deposition of sediments carried by meltwater from a retreating glacier. As the glacier melts, the sediment is deposited in a sinuous ridge-like formation. Eskers are typically composed of sand and gravel.
What are the youngest sediments found compared to the mid-Atlantic ridge?
The youngest sediments found near the Mid-Atlantic Ridge are typically associated with the oceanic crust formed at the ridge itself, which is less than a few million years old. These sediments primarily consist of pelagic clay, biogenic material, and volcanic ash, accumulating as the seafloor spreads. The rate of sedimentation is relatively low, meaning that the youngest sediments are generally found closest to the ridge and become progressively older with distance from it.
How do the sediments on the ocean floor vary in relation to an ocean ridge?
Sediments become thicker away from the mid ocean ridge. This is because the oceanic crust away from the mid ocean ridge is older than the crust close to it, so sediment has had more time to accumulate.
The sediment deposited at the edge of a glacier forms a ridge called a?
Moraine.
Does a esker represents a former meltwater channel or tunnel in glacial ice that was filled with sand and gravel?
Yes, an esker is a sinuous ridge formed by sediment deposited by meltwater flowing through a channel or tunnel within glacial ice. As the glacier retreats, the meltwater carries sand and gravel, which accumulate in the channel. Once the glacier has melted away, the remaining ridge of sediment is exposed, creating the distinctive landform known as an esker.
Does the thickness of ocean floor sediments decrease with distance from an ocean ridge?
yes
What are the sediments that are found on the ridge of the ocean floor called?
The sediments found on the ridge of the ocean floor are primarily known as "pillow lavas" and "basaltic sediments." These sediments are formed from volcanic activity, where magma erupts and cools rapidly upon contact with seawater, creating pillow-shaped formations. Additionally, hydrothermal vent deposits and other sediment types, such as biogenic and pelagic sediments, can also be present in these regions.
Ridge consisting of unsorted sediments deposited at the sides of a glacier?
Such ridges are referred to as lateral moraines. As a glacier moves, it shears debris, such as rock and soil, on both sides, and this unsorted sediment forms ridges along the edges of the glacier.
What is the sediment deposited by the edge of a glacier forms a ridge called?
It is known as moraine.
Is long ridge formed by boulders carried and deposited by a glacier moraine?
