What is a ridge zone?
A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. Ridge-push occurs when the weight of the ridge pushes the rest of the tectonic plate away from the ridge, often towards a subduction zone. At the subduction zone, “slab-pull” comes into effect.
What are ridges called?
The sides of the ridge slope away from narrow top on either side. The lines along the crest formed by the highest points, with the terrain dropping down on either side, are called the ridgelines. Ridges are usually termed hills or mountains as well, depending on size.
What are the 4 types of ridges?
Mid-Ocean Ridges: Types of Ridges
- Axial Ridge.
- Magnetics & Polarity.
- Fast/Slow Spreading.
What is ridge in fingerprint?
Terms used in Fingerprint Technology. Friction Skin -Skin that covers the inside surface of the hands and fingers and the bottom of the feet and toes. Friction ridges or papillary ridges – Elevated strips of skin that begin as raised apertures around the pores and then are joined together into rows forming the ridges.
What are the sides of a ridge called?
The sides of the ridge slope away from narrow top on either side. The lines along the crest formed by the highest points, with the terrain dropping down on either sides, are called the ridgelines. Ridges are usually termed hills or mountains as well, depending on size.
What are the characteristics of a mountain ridge?
A ridge or a mountain ridge is a geographical feature consisting of a chain of mountains or hills that form a continuous elevated crest for some distance. The sides of the ridge slope away from narrow top on either side. The lines along the crest formed by the highest points, with the terrain dropping down on either sides,…
What are oceanic ridges and where are they found?
Oceanic ridges are found in every ocean basin and appear to girdle Earth. The ridges rise from depths near 5 km (3 miles) to an essentially uniform depth of about 2.6 km (1.6 miles) and are roughly symmetrical in cross section .
What type of tectonic plate boundary forms a spreading ridge?
Oceanic spreading ridge: In tectonic spreading zones around the world, such as at the Mid-Atlantic Ridge, the volcanic activity forming new plate boundary forms volcanic ridges at the spreading zone.
