What is the boundary surface between two different rock types or ages of rocks?

An inhumed erosional surface that splits two strata of dissimilar ages or two rock masses is called unconformity. Generally, the older layer was exposed to erosion for a period of time before depositing the younger layer.

How far beneath the earth's surface would you have to go before you were no longer passing through rocks?
Roughly 2900 kilometers to the boundary between the mantle and the outer core which is a liquid.
What makes up earths surface?
70% of the Earth's surface is water. The rest is land masses that are made up of many different kinds of rocks.
Why can two igneous rocks have the same minerals but different names?
The rocks may have different textures
What is the dirrerence between extrusive and intusive rocks give an example of each?
The difference between extrusive and intrsive rocks are thatextrusive rock is a ingeous rock and formes by lava that erupes onto earth surface, and that intrusive rock is igneous rocks that hardenes beeatg earth's surface.
What processes found at convergent boundary will help form the following rocks?
The processes found at convergent boundary that help in the formation of rocks are subduction zones. Igneous rocks form around convergent boundaries.
What is the Basal surface of weathering?
Basal Surface of Weathering is also known as the Weathering Front, which is the boundary between weathered and unweathered rocks.
How the rocks are different from rocks associated with plate-boundary orogeny?
How are what rocks different?

Roughly 2900 kilometers to the boundary between the mantle and the outer core which is a liquid.
How is magma different from rocks on Earth's surface?
Magma is under the surface of Earth's crust. Rocks on earth's surface are well ... on Earth's surface. Magma is also molten rock, not solid rock like the rocks on earth's surface.
What processes at a divergent boundary will 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.

What thin outer layer of the lithosphere that forms earths surface is the?
the thin layer that humans inhabit is called the crust. it is the smallest layer compared to the others. it is the boundary between the liquid and solid innerds and the atmosphere. including all of it's content below such as soil, sediments, sedimentary rocks and weathered crystalline rocks.

What is the difference between instrusive rocks and extrusive rocks?
Extrusive rocks form above the surface, cooling quickly and bearing a glassy or fine texture and may be vesicular. Intrusive rocks form below the surface and form slowly, giving it a coarse texture.
What makes a fault different from other kinds of fractures in rocks?
Rocks on either side of a fault move along the surface of the fault.
