Answer:
3. Rocks erode and sediment is deposited.
4. No sediment is deposited over a long time.
Explanation:
An unconfomity is a break in stratigraphic record of a place usually as a result of non-deposition or erosion.
In a sequence of sedimentary rock strata some surfaces called unconformity surfaces gives clues about the depositional history of a particular place. During an unconfomity, there is usually no sediment deposition and when deposition resumes, the underlying rocks and the new ones will not share the same attribute especially by age. Unconformity can also be as a result of erosion of a sequence.
In the case of non- conformity, a sedimentary rock is deposited above an igneous or sedimentary rock. Option 5 is a simple example of an igneous intrusion called a sill. It is not unconformity.
Answer:
When microorganisms release carbon dioxide into the soil, the acidity of water surrounding soil particles is increased. This increase in acidity allows for rock present in soil to be broken down, releasing minerals into the soil. These minerals are then available for use by plant life.
In Earthquake testing, the engineers are using the world largest shake tables to test new construction methods for buildings in the areas prone to the earthquake.
<u>Explanation:</u>
They believed that they have the devised a system to build the taller wood-frame buildings that can still safely withstand even very powerful tremors. To withstand the collapse, the buildings need to redistribute the forces that travel through them during a seismic event.
Shear wells, cross braces, diaphragm, and moment-resisting frame are the central reinforcing the building. Shear wells are the technology of the useful building. That helpful to transfer the earthquake forces.
The answer for the question is Migraine<span>. Migraines Headaches are extremely, nearly paralyzing headaches that are located on one side of the head and are sometimes accompanied by dizziness, nausea, or vomiting. They normally develop in two phases; The first phase, in which blood vessels in the brain narrow (vasocontsriction), such that the flow of blood to arts of the brain is reduced. Second phase; occurs when the blood vessels expand, such that blood flows through them rapidly, thus stimulating many neuron endings and causing pain. </span>
