Answer: a. Heavy rain and thunderstorms followed by lighter stratiform precipitation.
Explanation:
In their order of severity, thunderstorms range from single-cell, multi-cell, squall line, supercell, bow line to Mesoscale Convective systems (MCS)
. An MCS, therefore is a serious weather condition.
A Mesoscale convective system is an organized, group of thunderstorms with a wide geographical coverage and can last for hours. It can come with hail, flash floods, lake effect snow and trigger disasters such as tropical cyclones.
Answer:
Super position
Faunal Succession
Crosscutting Relationships
Inclusions
Explanation:
Superposition: The most basic concept used in relative dating is the law of superposition. Simply stated, each bed in a sequence of sedimentary rocks (or layered volcanic rocks) is younger than the bed below it and older than the bed above it. This law follows two basic assumptions: (1) the beds were originally deposited near horizontal, and (2) the beds were not overturned after their deposition.
Faunal Succession: Similar to the law of superposition is the law of faunal succession, which states that groups of fossil animals and plants occur throughout the geologic record in a distinct and identifiable order. Following this law, sedimentary rocks can be “dated” by their characteristic fossil content. Particularly useful are index fossils, geographically widespread fossils that evolved rapidly through time.
Crosscutting Relationships: Relative ages of rocks and events may also be determined using the law of crosscutting relationships, which states that geologic features such as igneous intrusions or faults are younger than the units they cut across.
Inclusions: Inclusions, which are fragments of older rock within a younger igneous rock or coarse-grained sedimentary rock, also facilitate relative dating. Inclusions are useful at contacts with igneous rock bodies where magma moving upward through the crust has dislodged and engulfed pieces of the older surrounding rock.
Answer:
2 opposite forces
Explanation:
Conflict between two opposite forces idead or belief
for short
2 opposite forces
The answer to the question is true
Answer:
The intermediate to felsic eruptions may be usually moderately to highly explosive
Explanation:
- Felsic lavas are hot, high in silica and volatiles, and have a high viscosity of fluid matter. They are thick and heavy and resistance movements.
- They thus represent the shielded nature of volcanoes etc. Fluid lava flow, tephra, lapilli, and volcanic bombs.
- Felsic magma is rich in feldspar, and silica as opposed to mafic magma which is rich in magnesium and iron.
- Felsic magma is usually acidic.
- As a result of the high intensity of volcanic eruptions, the lava is sticky and dark in color also it's bulky, etc. An example of Mount Saint Helens that erupted destroying both property and human life.
