If divergent plates cause new land to be added to the Earth why doesn't the Earth just grow and grow?
While divergent plates do create new land through processes like seafloor spreading, the Earth doesn't continually grow because this new land is balanced by subduction, where tectonic plates are pushed back into the mantle at convergent boundaries. The Earth's size remains relatively constant as the material created at divergent boundaries is offset by the material lost at subduction zones. Additionally, the recycling of crustal material ensures that land is constantly being transformed rather than simply accumulating.
What else can I help you with?
Should water be added to car battery?
Only if clean rainwater or distilled, and even then not very much. Just enough to cover plates, and charge immediately on long 2 amp charge.
Can you Compare Convergent Plate Boundary and Divergent Plate Boundary?
Okay this is going to be long :X IN GENERAL... Divergent Plate Movement (plates move away from each other)- Continental and continental, oceanic and oceanic -Constructive Plate Boundary Convergent Plate Movement (plates move towards each other)- Continental and Oceanic, Oceanic and Oceanic, Continental and Continental -Destructive Plate Boundary Transform Plate Movement (plates sliding past each other)- Continental and Continental -Conservative Plate Boundary DIVERGENT PLATE MOVEMENT When plates move apart, magma wells up from Earth's mantle to form a new ocean floor with mid-oceanic ridges. It is a constructive plate boundary because new land crust is being created. O & O (Oceanic and Oceanic) Oceanic Ridges and Submarine volcanoes are formed. Shallow earthquakes may occur and there may be volcanic activity. Magma from the deeper mantle wells up into the gap formed when two oceanic plates move away from each other, and some of it melts and is erupted on the surface as lava, while others are injected near the surface to crystallize as other igneous rocks. The seafloor may also spread, and magma rises to the floor and solidify, forming new crust. Therefore it is a constructive plate boundary as new crust is formed and added to the ocean floor. An example of the resulting landforms would be the Mid-Atlantic Ridge. C & C (Continental and Continental) When two continental plates move away from each other, a sea is formed. E.g. Red Sea. CONVERGENT PLATE MOVEMENT When plates move towards each other, they may collide. When 2 oceanic plates collide, plate edges are bent into a deep trench called thesubduction zone. It is a destructive plate boundary because the subducted plate is destroyed in the process. O & O Subduction takes place, and the over-riding plate (the plate above) folds and form islands, whilst the heavier plate sinks into the mantle of the Earth and is melted away by the magma. The magma rises and forms volcanoes. E.g. Japan. C & O When an oceanic plate collide with a continental plate, the oceanic plate sinks as it has a larger density. Lithosphere materials from the oceanic crust are subducted in the trench whilst the continental border is fractured, folded and uplifted. Magma rises and a mountain accompanied by volcanic activity are formed. E.g. Andes Mountains. C & C When two continental plates collide, neither sinks because they have similar densities. The continental lithosphere buckles and is uplifted instead, forming fold mountains. Little volcanic activity occur as rocks from the lithosphere do not sink deep into the asthenosphere (upper mantle zone) Earthquakes, faulting and folding however, are common. E.g. Himalayas. TRANSFORM PLATE MOVEMENT Occurs when two plates slip past each other. Tear faults form, accompanied by earthquakes due to great amount of stress built up in these areas, but there is little volcanic activity and little crustal material is destroyed.
What was the part of the constitution that was added later?
its was later added that mklsmkxjsnjk
Why 2 of gypsum is added to cement?
Gypsum is added to cement to decrease the setting time.
It is possible to register the birth certificate of a newborn baby if the FATHER doesnt want to sign on it and doesnt want to use hes SURNAME?
Yes, you can. Most states prohibit naming a father without either a marriage license or a DNA test. Of course, if you are unmarried and sue the child's father for child support, the father's name will be added to the birth certificate. Also, in almost all child support cases, the child's last name is changed to the father's last name.
What two tectonic forces keep the earth the same size?
None. The Earth remains the same size because it does not lose or add material (except for meteorites, which are negligable. Tectonic forces move the -parts- of the Earth around, moving the water out of the way as needed, but nothing is added to or taken from the Earth's size.
Where is the new earth's crust added as it pertains to plate boundaries?
New Earth's crust is added at divergent plate boundaries, where tectonic plates move away from each other. At these boundaries, molten rock rises from the mantle and solidifies, creating new crust. A prime example of this is the Mid-Atlantic Ridge.
How does the movement of the earth's crustal plates cause the formation of ocean basins?
The movement of earth's crustal plates causes divergent boundaries where plates move apart, allowing magma to rise from below and solidify to form new crust. This process creates mid-ocean ridges, which is where new oceanic crust is formed. Over time, as more crust is added, the ocean basin widens and gets deeper.
What is the midatlantic ridge?
The Mid-Atlanic Ridge is the divergent boundary that is responsible for seafloor spreading. Consisting mostly of divergent boundaries, with transform faults as well, this is the site where new oceanic crust is added, increasing the size of the ocean. This location is dotted with underwater volcanoes as igneous basaltic magma is added to fill in the gap left as the oceanic plates drift away.
What type of plate boundary is Hekla the volcano formed?
A diverging is the type of plate boundary that the Hekla volcano formed. Hekla last erupted in 2000. It is located in Iceland. ADDED. Also called a "constructive" plate boundary, because the upwelling magma adds rock to the edges of the two plates.
What happens when plates of movement move apart?
This is known as a divergent boundary. Divergent boundaries are constructive boundaries as opposed to convergent boundaries which are destructive. When plates move away from each other, magma is allowed to seep up and fill the crack. Thus, new rock is added onto the plate as they move away from each other. An example of the Earth taking care of itself.
Which mountain is formed when new material is added to earth's surface?
A mountain is formed when tectonic plates converge and push against each other, causing uplift of the Earth's surface. This process can involve the collision of two plates, resulting in the formation of mountain ranges such as the Himalayas.
Why is the youngest oceanic crust found near the divergent plate boundaries?
New rock is formed near the mid-oceanic ridge as oceanic plates diverge or separate from each other. Hot rocks rising from the asthenosphere melt from decompression as they rise, filling the fault and forming new basaltic oceanic crust. As new crust is added, older crust is pushed away. Therefore, the further away from the mid-oceanic ridge, the older the crustal rocks.
Why isn't air added until the ice cream mixture is cooled?
because is doesnt want to be added till its cooled :)
Is the amount of water on earth added to every time it rains and why?
is the amount of water on earth added to every time it rains
Is Eyjafjallajokull on a constructive plate boundry?
Yes. It is believed to have erupted in 2010 twice because of the constructive margin. The plates were pulled apart by convection currents then because of this basalt lava seeps in to form a new crust beneath the sea and existing volcano. Much of the magma was intruded as dolerite dykes (thin sheets of igneous rock.) New lava and dykes then added extra crust at each side of the spreading ridge.
Why does the ocean plate and the continental plate move against each other?
The Earth's rocky outer crust solidified billions of years ago, soon after the Earth formed. This crust is not a solid shell; it is broken up into huge, thick plates that drift atop the soft, underlying mantle.The plates are made of rock and drift all over the globe; they move both horizontally (sideways) and vertically (up and down). Over long periods of time, the plates also change in size as their margins are added to, crushed together, or pushed back into the Earth's mantle. These plates are from 50 to 250 miles (80 to 400 km) thick.Oh and if you want to know how to make things huge: go to power point and copy down what you want then copy and paste.
