Answer: C. The overall temperature of the Earth will increase.
Explanation:
Let's begin by explaining that Earth has a layer, the atmosphere, that is almost transparent to solar radiation, which is composed mainly of shortwave radiation (ultraviolet (UV) and visible light). Then, this layer allows to pass most of the sunlight (visible light and a small part of the UV radiation), without being absorbed.
When this radiation reaches the Earth, it is absorbed by the water 
), soil, plants, animals; well, everything that inhabits and also the buildings. Once this absorption process ends, the light turns into long wave (IR) radiation, generating heat that is then released into outer space and known as albedo.
However, due to climate change (caused by the humankind), the Earth now tends to absorb more energy than it emits to the space as IR radiation. If this process is mantained for a long term, the planet's global temperature will highly increase.
Answer:
The answer is C.
Explanation:
That process occurs when the water inside of rocks freezes and expands. That expansion cracks the rocks from the inside and eventually breaks them apart.

Answer:
The Bulk density = 1.3 g/cm³
the porosity of the sample is 132 cm³
Explanation:
Given:
Volume of cylinder = 260 cm³
Mass of container and the soil = 403 g
Mass of the empty container = 65 g
Thus,
The mass of the soil is = 403 - 65 = 338 g
Now,
The Bulk density = 
or
The Bulk density = 
or
The Bulk density = 1.3 g/cm³
also,
average particle density for mineral soil is usually given as 2.65 g/cm³
i.e the air present in the given soil sample has reduced its density from 2.65 g/cm³ to 1.3 g/cm³
The mass of the whole sample = Volume × Density
= 260 × 2.65
= 689 gm
but,
The actual mass of the dry sample = 338 g
thus,
Mass of air in the sample = 689 - 338 = 351 g
Therefore,
the volume of 351 g soil = 
= 
= 132.45 cm³
so the porosity of the sample is 132 cm³
