Sedimentary rocks form by breaking down other kinds of rocks into small particles and washing or blowing them away; metamorphic rocks form from other rocks and igneous rocks form by melting other rocks. Igneous Rocks: form by crystallizing melted material (magma).

The rock cycle is a process in which rocks are continuously transformed between the three rock types igneous, sedimentary and metamorphic. If the sediments are buried under further layers of sediment, they can become lithified to produce a sedimentary rock. Magma is produced when rocks are melted.

Soil is formed through the process of rock weathering. Weathering is the breakdown of rocks into smaller particles when in contact with water (flowing through rocks), air or living organisms. This acidifies water in rocks leading to further chemical reaction with rock minerals.

The accumulation of material through the action of water, wind and gravity also contributes to soil formation. These processes can be very slow, taking many tens of thousands of years. Five main interacting factors affect the formation of soil: parent material—minerals forming the basis of soil.

Earth’s oldest soil could be tucked away in an ancient rock outcrop in Greenland, according to new research. Dating back some 3.7 billion years, the suspected soil—exposed underneath a retreating ice cap—could potentially contain fossilized traces of primordial life.

Even better for growing plants in containers are artificial soils or soilless mixes. They are called artificial because they contain no soil but are made up of peat, perlite, vermiculite, and nutrients. They have a lot of plusses over soil. They are clean, lightweight, provide for excellent drainage, and easy to get.

Full Basement Full basements are the most expensive foundation type averaging $18 per square foot.

Answer. ✒House don’t be built on soft soil because it will led to be damage of house. This is because if the soil is soft in nature then we are not able to build a strong base house which can live longer without any damage.

There are three main foundation types; basement, crawlspace, and concrete slab.

Isolated footings are provided where the soil bearing capacity is generally high and it comprises of a thick slab which may be flat or stepped or sloped. This type of footings are most economical when compared with the other kind of footings. Economical when columns are placed at longer distances.

Treated wood pilings are a time-tested foundation, so it is not surprising beach home builders call wood pilings the foundation of choice for most of their projects. A home built in any flood zone (beach, coastal area, etc.) must be elevated above the floor level.

Slab – The Most Popular Foundation Type Because a slab is by far the most cost-effective choice, customers flock to this budget-friendly option. It’s quick and easy, as far as foundations go – a slab can often be poured directly on the ground or on a bed of gravel.

If you’re building a home, a concrete slab makes sense because of its low cost. It’s the cheapest option available, and, comparatively speaking, it’s the quickest solution. The right crew can lay a concrete slab foundation in a short period of time, and the drying process doesn’t take much longer.
