Question

need help with this few questions!!!

1. Tensional stress ___________________________.

a.tends to compress rocks

is caused by the load of overlying rock

is between ninesional and elevensional stress

is due to sedimentary layering

acts to pull rocks apart

Consider this fairy tale (which might be true) for the order of the earliest stages of our planet: Earth started as a completely molten ball after accretion then differentiation. Then it became solid. Then continental crust was formed. Then atmospheric weathering became an active process. Then plate tectonics kicked in, as did volcanism, and mountains were built. Which is the most likely order for the creation of rock types for this scenario, one rock type was created at a time (before the rock cycle was fully evolved)?

a.Metamorphic then sedimentary then igneous

.Sedimentary then metamorphic then igneous

c.Igneous then metamorphic then sedimentary

d.Plutonic then iconic the demonic

e.Igneous then sedimentary then metamorphic

f.Metamorphic then igneous then sedimentary

g.Sedimentary then Igneous then extrusive

Molten then crystaline then sedimentary

Explanation / Answer

Q.1) Tensional stress ___________________________.

Ans. e. acts to pull rocks apart.

Q.2) Consider this fairy tale (which might be true) for the order of the earliest stages of our planet: Earth started as a completely molten ball after accretion then differentiation. Then it became solid. Then continental crust was formed. Then atmospheric weathering became an active process. Then plate tectonics kicked in, as did volcanism, and mountains were built. Which is the most likely order for the creation of rock types for this scenario, one rock type was created at a time (before the rock cycle was fully evolved)?

Ans. e. Igneous then sedimentary then metamorphic.

Q.3) What is the name for the deformed sequence of layers in the accompanying image labeled "B" ?

Ans. Syncline.

It is Concave upward.

Q.4) What is the name for the deformed sequence of layers in the accompanying image labeled "A" ?

Ans. Anticline.

It is Convex upward.

Thats all

Thank you.
