Why does the earths surface not get any smaller or larger using divergent and convent plate boundarys?
The Earth's surface remains relatively constant in size due to the processes occurring at divergent and convergent plate boundaries. At divergent boundaries, tectonic plates move apart, allowing magma to rise and create new crust, which offsets the surface area lost at convergent boundaries where plates collide and one is subducted into the mantle. This recycling of crust ensures that, overall, the Earth's surface area remains stable. Thus, any new crust formed at divergent boundaries is balanced by crust being destroyed at convergent boundaries.

What processes found at a divergent boundary help form the following rocks?
The process of upwelling magma is found a divergent boundaries. As this magma nears the surface it decompresses, and some of it flows onto the surface of the Earth as lava. Magma that solidifies beneath the surface of the Earth hardens into gabbro while lava on the surface of the Earth hardens into basalt. Both of these are igneous rocks. Metamorphic rocks are formed from the heat flowing from the igneous rocks. Sedimentary rocks are formed from the sediments collecting in the basins created from rifting (that is, the divergent boundaries). Metamorphic and sedimentary rocks are not considered to be formed at divergent boundaries.
When breaking a rock into smaller pieces the surface area to volume ratio?
When a rock is broken into smaller pieces, the surface area to volume ratio increases. This is because the total surface area of the smaller fragments is greater relative to their combined volume compared to the original rock. As the pieces get smaller, more surfaces are exposed, allowing for increased interaction with environmental factors like weathering and erosion. This higher ratio can enhance processes such as chemical reactions and physical breakdown.
What are the similarities of divergent and transformed fault boundaries?
Divergent and transform fault boundaries are both types of plate boundaries where tectonic plates interact. At divergent boundaries, plates move apart, creating new crust as magma rises to the surface, while at transform boundaries, plates slide past each other horizontally, often causing earthquakes. Both types of boundaries are associated with seismic activity and are crucial in shaping the Earth's geology. Additionally, they contribute to the dynamic nature of the Earth's lithosphere.
Why is a DVD able to store 4.3GB of data even though it is the size of a normal CD?
Single layer recordable DVD's can store 4.3GB of data. Data is stored on CD's and DVD's via reflective and non reflective pits on the surface of the media. These "dots" are much smaller on DVD's which gives you more room to store information on the surface of the disc. Dual Layer DVDs hold 8.5GB. The pits on a DVD are much smaller and closer together than those on a CD. The new BlueRay disks can pack the pits even closer together because the blue light used to read them has a smaller wavelength and hence is able to resolve smaller details on a disks surface. CDs are read by a red or infrared light which has a much longer wavelength and is not able to resolve smaller pits on a disks surface.
Why do broken down pieces of rock have more surface area then larger pieces?
Broken down pieces of rock have more surface area than larger pieces because the process of breaking creates additional surfaces that were previously internal. Each fragment exposes new surfaces that were not visible in the larger, intact rock. As the size of the rock decreases, the ratio of surface area to volume increases, resulting in a greater total surface area for smaller pieces. This increased surface area can enhance weathering and chemical reactions, making smaller fragments more reactive.

Plates on the surface move away from each other?
They are called divergent plate boundaries.
When a hotspot rises and cracks the surface is it a convergent divergent or transform boundary?
When a hotspot rises and cracks the surface, it is typically associated with a divergent boundary. At divergent boundaries, tectonic plates move apart, allowing magma from the mantle to rise up and create new crust.
