How can chemical weathering contribute to physical weathering?
lora16 [44]

A-leads to the abrasion of rocks and minerals

A-dense vegetation cover

True

Explanation:

Weathering is the physical disintegration and chemical decomposition of rocks to form sediments and soils.

Agent of weathering are wind, water and glacier.

Chemical weathering contributes to physical weathering in that it leads to the abrasion of rocks and minerals.

During chemical weathering, a rock chemically combines with materials in the environment and weakens it.

When physical weathering processes are induced, grains produced independently weakening of bonds in rocks grind against one another and wears each other off.

An area with a dense vegetation cover undergoes rapid chemical weathering:

  • Plant roots penetrates deep into the rock and increases the surface area of chemical action.
  • Plants produce chemicals that combines with rocks and causes them to decay.
  • Since the area is always moist, chemical action becomes more severe.

Buildings and statues made of stone are subjected to the same degree of weathering as rocks exposed naturally.

This is true.

Statues and buildings weather just like rocks we find in nature.

It is the same sunshine and rain that impacts rocks that also impacts buildings and statues.

So they degrade at the same rate except they are protected.

For the following species, draw a Lewis structure for one important resonance form. Include all lone pair electrons and assign f
Gemiola [76]

Answer:

The Lewis structures are shown in the figure

Explanation:

The lewis structure will be drawn using following steps

i) we will calculate the total number of valence electrons in the molecule

ii) will assign one bond (two electrons in between two atoms)

iii) then distribute the rest of the valence electrons as lone pair or shared pair based on completion of octet.

The structure of each molecule is given in the figure.

Valence electrons:

NO_{2}^{+}

V.E = 5 +(2)6-1=16

NO_{2}F

V.E =5 +(2)6+7=24
