What is the oceanic ridge?

What is the oceanic ridge?

An oceanic ridge is any elongate elevation of the deep seafloor that has steep slopes and irregular topography.

How oceanic ridges are formed?

A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.

Which is characteristic of mid-oceanic ridges?

Principal characteristics. 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. They can be thousands of kilometres wide.

Which of the following describe the oceanic ridge system?

Which type of boundaries movement causing the formation of oceanic ridges?

Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt.

What is the function of the Mid Oceanic Ridge?

Mid-ocean ridges represent one of the most important geologic processes shaping the Earth: Over the last 200 million years, two-thirds of the Earth has been resurfaced through this process of seafloor spreading, either at conventional mid-ocean ridge spreading centers or at spreading centers in back-arc basins behind …

Which mid-ocean ridge is spreading the slowest?

The Ridge is named after him, and the name was recognized in April 1987 by SCUFN (under that body’s old name, the Sub-Committee on Geographical Names and Nomenclature of Ocean Bottom Features). The ridge is the slowest known spreading ridge on earth, with a rate of less than one centimeter per year.

What are common in rift valleys and oceanic ridges?

Rift valleys and ocean ridges are common in the aspect that they are both similar seismic structures, meaning both were formed out of the moving tectonic plates. Furthermore, rift valleys and ocean ridges were the result of two plates, moving away from each other, respectively the continental and oceanic plates.

What is the difference between rifts and ridges?

If the boundary is found between two continental plates you are left with a rift valley. If two oceanic plates begin moving away from each other it creates a mid-oceanic ridge. Continental plates are less dense, and thus float much higher on the mantle.

Why Rift Valley is found between two block mountains?

A rift valley is a linear shaped lowland between several highlands or mountain ranges created by the action of a geologic rift. Rifts are formed as a result of the pulling apart of the lithosphere due to extensional tectonics. The linear depression may subsequently be further deepened by the forces of erosion.

What are the common in the four pictures of rift valleys and oceanic ridges?

Answer: The common among the pictures is the formation of divergent plate boundary, where it forms the rift valleys and oceanic ridges.

What are the common in the four pictures science 10?

Answer: Common among the pictures is the formation of divergent plate boundary, where it forms rift valleys and oceanic ridges.

What is common in the four figure?

Answer: 1. All four figures shows 2 lines intersecting or intersecting lines. Two distinct lines intersecting each other at 90° or a right angle are called perpendicular lines.

Where is the easiest place to pull the blocks of wood?

Yes. Although the sandpapers were placed in between the block of woods where they all meet, you can still pull the blocks of woods despite the grinding effect. Because of the divergent plate boundaries between the blocks 1 and 2 and blocks 3 and 4, it causes the moving away motion of each other.

What do you see is common in the four pictures?

Answer: Rift valleys and oceanic ridges represents the 4 pictures. However, what is common among these pictures is the formation of divergent plate boundary.

What is the interaction between Block 1 and 3 How about 2 and 4?

Answer Expert Verified Remember that the presence of a ridge is an indication of diverging plates, and as the plates diverge between the two segments of the mid-ocean ridge, the adjacent slabs of crust are grinding past each other (blocks 2 and 3, blocks 1 and 3, and blocks 2 and 4).

How will you describe the interaction between Block 2 and 3 as you pull each block?

Answer Expert Verified If you pull either of these two blocks, this will cause a shake and change to another block. They will be moved apart. This illustration is the same with tectonic plates which are moving from time to time and affect the other plates when some of them move that causes us shakings.

What happens when a continental plate converges with an oceanic plate Brainly?

Answer. Answer: When oceanic crust converges with continental crust, the denser oceanic plate plunges beneath the continental plate. This process, called subduction, occurs at the oceanic trenches.

What can you see on the surface of the bond paper?

On the surface of any bond paper that is used in the experiment we have made an observation that it is is a wet patch that we see on the bond paper because of the contact it has with the test tube.

Which of the features will be the most active the least active?

Answer Expert Verified The most active volcano is the youngest one (the one that is currently on top of the magma source). While the least active volcano, is the oldest (because it is already cut-off from the source of magma).

What do you see on the paper when the glass of water was exposed to sunlight?

Answer. of water was exposed to sunlight? Answer: You will see a rainbow.

What do the bond paper represent?

It is an uncoated stock that is used for writing, drawing, and of course printing things like letterhead and business documents. Its name comes from its use as a paper for government and legal documents such as (you guessed it) government bonds. Today, bond paper is often found in the average copier and printer.

What is the thickness of bond paper?

Notes about Paper Thickness

Paper thickness*1 Paper weight
Thin Paper*2 52–59 g/m2 (14–15 lb. Bond)
Plain Paper 1 60–74 g/m2 (16–20 lb. Bond)
Plain Paper 2 75–81 g/m2 (20 lb. Bond)
Middle Thick 82–105 g/m2 (20–28 lb. Bond)

Is bond paper coated?

Uncoated bond paper is typically used for everyday drawing, printing, and copying. The coating fills in the tiny pits in the base paper, providing an even, less porous surface for the inks. Text, color renderings, and photographs look sharper on coated papers because less ink soaks into the paper.

What bond is normal paper?

For instance, regular everyday copy paper is most commonly referred to as a “20 lb. bond” but is other times referred to as a “50 lb.

What is erasable bond typing paper?

Eaton’s Corrasable Bond is a trademarked name for a brand of erasable typing paper. Erasable paper has a glazed or coated surface which is almost invisible, is easily removed by friction, and accepts typewriter ink fairly well. Removing the coating removes the ink on top of it, so mistakes can be easily erased once.

Is Bond Paper good for printing?

Bond paper is a durable paper that is suitable for electronic printing and use in office machines, including copiers and network and desktop printers. People typically use it for letterhead, stationery, business forms, and a variety of documents produced with inkjet and laser printers.

What is the difference between bond and text paper?

Bond paper is manufactured exclusively to be uncoated sheets. While text weight paper is manufactured to be uncoated or coated. You will never find a glossy or a matte “bond” sheet. However, the uncoated text shares a lot of the same manufacturing processes as the matte and glossy “text” sheets.
