What products are made from lava?
Lava makes many rocks that are very fertile with minerals that plants need, and the land around volcanoes is rich and fertile and is very good to be used for farming. Lava rocks (extrusive igneous rocks) make useful road building materials as aggregates, and can be cut and polished for use as a decorative stone inside buildings. Pumice is used as landscaping rock and as an abrasive in cleaning products and some polishing compounds. In less recent history, lava rocks were used as building materials, grinding stones, toolmaking, and weapon construction.
How are the laws of superposition and crosscutting relationships used to determine the age of rocks?
They are used to determine the relative ages of rocks by stating that younger rocks lie above older rocks, and that rocks that cut through a layer are younger than the existing layer.
What is the main type of energy used to help converts rocks in metamorphic rocks in the rock cycle?
Sedimentary rocks

What is the diameter of coarse aggregates that used to strip foundation?
20mm
What is fine aggregate?
Fine aggregates are the aggregates whose size is less than 4.75 mm.Example: Sand is used as fine aggregate in the preparation of concrete and cement mortar.
What are the components of concrete?
cement fine aggregates and course aggregates and water for the hydration of cement are the main component of plain cement concrete. and for RCC M-S bars are used with these component.
Why is wind an agent of erosion?
Wind can pick up small aggregates and soil particles and displace them in another soil series. Wind can also erode rocks by picking up particles of sand that then slowly erode at the exposed rocks.

Why suitable coarse and fine aggregate used in the concrete ingredient?
aggregates are used to concrete for following purposes: 1.if totally binding materials like cement is used in concrete, the cost of concrete will be high which is uneconomical. 2.to prevent high shrinkage of concrete mix fine aggregates are used. 3.to increase the volume of concrete mix aggregates are used.
Which things used in IPS cement concrete?
Different minerals used in concrete are cement, water, aggregates, syphorites.
What are the different types of aggregates?
There are two different types of aggregates namely,Fine aggregates - size of the aggregate is less than 4.75 mmExample : SandCoarse aggregates - Size of the aggregate is more than 4.75 mmExample : Gravel
