77julia77 [94]

Answer:

$A=\dfrac{x^2}{2}$

Explanation:

The diagonal of a square is x units.

Let the side of a square is s.

Using pythagoras,

$s^2+s^2=x^2\\\\2s^2=x^2\\\\s^2=\dfrac{x^2}{2}$

The area of the square is,

A = s²

So,

$A=\dfrac{x^2}{2}$

So, the area of a square is $\dfrac{x^2}{2}$ sq units.

A. Describe the roles of mechanical and chemical weathering in the formation of the sediments that are eventually incorporated i

Serhud [2]

Answer:

As explained below.

Explanation:

Sedimentary rocks that are formed due to the accumulation of sediments that are derived from the deposition of small particles and their cementation of minerals and organic particles in the seafloor by the impact of various geological and earth processes like the wind, water, and glacier erosion.

Earth's crust is covered by 73% of sedimentary rocks and about 8% of the total crustal surface. Based on their formation, these rocks are thus classified as Siliciclastic, Carbonate, Evaporite, Iron-rich, and Phosphatic sedimentary rocks.

The color of these rocks is always determined by the iron and oxide contents, their size texture is a result of the density and permeability of the rocks like in the case of sandstone and limestone.

The relationship between the plate tectonics and the earthquakes is explained through the seismic waves that travel; through the three-layer of the earth from core to mantle to crust.

Earthquakes are directly related to plate boundaries as these are areas where these waves come out in the form of shocks and shaking of lands thus we expect of seeing three types of boundaries as Convergent, Divergent and Transform.
