Sediments are pieces of rock that come from other rocks that were eroded or broken by wind, water or other mechanical forces. Debris are pieces of other materials that were also swept away.
When these sediments and debris settle, they create layers. These layers are called beds. In time, several layers of other sediments and debris form on top of each other which press down onto the previous layers. Because of the pressure from the weight of the newer layers, the sediments and debris are pressed together and go through cementation. These then produce sedimentary rocks.
Metamorphic rocks form when rocks undergo heat and pressure. The heat comes from the friction resulting from the pressure. The heat can also come from radioactive decay. The rocks then slowly bake into new rocks called metamorphic rocks.
Igneous rocks form when magma and lava cool down. Magma is molten fluid found beneath the surface of the Earth. Lava is magma that has reached the surface of the Earth. When they cool down, they crystallize which make igneous rocks.
The difference between intrusive and extrusive igneous rocks is that one is made beneath the Earth and the other is made on the surface of the Earth. When magma cools, it takes a long time and the product of this cooling are intrusive igneous rocks. On the other hand, extrusive igneous rock is the result of lava cooling, which does not take as long to cool down because it occurs on the surface of the Earth.
Examples of the following types of rocks:
Sedimentary: limestone, sandstone, siltstone
Metamorphic: Marble, gneiss, slate
Igneous: Gabbro (intrusive), granite (Intrusive), obsidian (extrusive)
<h2>Answer:</h2>
<u>The correct option is</u><u> (C) its greater tensile strength </u>
<h2>Explanation:</h2>
Elasticity is the property of any material to return to its original shape when it is de-shaped. for example a spring comes to its original shape when it is stretched and then released. so the property that brings the spring back to its original form is called elasticity. On the other hand tensile strength is the maximum stress that a material can withstands before it breaks. Since polymers are also elastic so the greater tensile strength means greater elasticity.
Faults are cracks on the ground that is caused by the movement of the plate tectonics. They usually cause rocks to break.
Anitclines and synclines form when rocks are also put under stress, but they fold, not necessarily break apart. They create sharp folds.
Island arcs are formed through volcanic events and not rocks.
Mid ocean ridges are formed when oceanic plates move apart.
Looking at their differences, the answer to your question is B.
<span> For this case we have the following number:
1,000,000
We note that the number has 7 significant figures.
To write it in scientific notation we must write the number as follows:
</span>

<span> Where,
a: first significant figure
b: Exponent that represents the rest of significant figures.
Rewriting the number we have:
</span>

They are short on water because the environment is not the same everywhere some are more dry so not water is there at all or just to hot like a dessert
