What is the difference between a rift valley and a spreading ridge

Click to see full answer. In this manner, what is the difference between a rift and a ridge? The two words are nearly opposites. A rift is a break, crack, split, or fissure. If you imagine a glacier breaking into two pieces with a long narrow crevice between the two halves, you are imagining a rift.

A ridge is high narrow elevation, such as an extended narrow hilltop or a mountain range. Secondly, what is the Rift Valley? A rift valley is a linear shaped lowland between several highlands or mountain ranges created by the action of a geologic rift or fault. A rift valley is formed on a divergent plate boundary, a crustal extension or spreading apart of the surface, which is subsequently further deepened by the forces of erosion.

Continental rift valleys and rift valley along the center of the Mid-Oceanic Ridge system Earth, pg A trench is a long, narrow, steep-sided depression of the seafloor formed where a sub ducting oceanic plate sinks into the mantle causing the seafloor to bend downward like a flexed diving board Earth, pg As tectonic plates move away from one another at mid - ocean ridges , molten rock from the mantle may well up and harden as it contacts the frigid sea, forming new oceanic crust at the bottom of the rift valley.

Over millions of years, the Mid -Atlantic Ridge has formed rift valleys as wide as 15 kilometers 9 miles. Asked by: Chi Unnikrishnan asked in category: General Last Updated: 10th March, What is the difference between a rift valley and a spreading ridge? The major difference between different types is what type of plate the divergent boundary is between. If the boundary is found between two continental plates you are left with a rift valley.

This leads to steep mountainsides spreading apart from a widening valley. What will happen if a Rift Valley continues to pull apart? 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. Answer: Rift valleys and oceanic ridges represents the 4 pictures. However, what is common among these pictures is the formation of divergent plate boundary.

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.

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. 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. 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. 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. 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.

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. 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. 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.

Bond paper is manufactured exclusively to be uncoated sheets. While text weight paper is manufactured to be uncoated or coated. Begin typing your search term above and press enter to search.

It is an active continental rift that began millions of years ago, splitting at 7mm annually. Rift valleys are found both on land and at the bottom of the ocean, where they are created by the process of seafloor spreading.

The idea that humans evolved in Africa can be traced to Charles Darwin. The system is some 4, miles 6, km long and averages 30—40 miles 48—64 km wide. It extends c. What is the difference between a rift and Ridge? Can rift valleys be underwater?
