If a mineral has a parent to daughter ratio of 1:3 (one parent atom for every three daughter atoms), how many half-lives have passed since the mineral formed?
a. 0
b. 1
c. 2
d. 3
e. 4
Answer:
c. 2
Explanation:
Given that
Parent to daughter ratio = 1:3
Based on the above information, after considering the 1 half-life of radioactive isotope there is one-half of the real radioactive atoms of the parent left also the equivalent number of daughter atoms produced
Therefore after one half, the ratio between parent and daughter atom is 1:1
Now after the second half, half of the left parent atom would be transformed into the daughter cells
This remains a quarter of parent atom and 3 quarter of daughter atoms
So, the ratio of 1:3 would be shown after 2 half-lives
After it experiences a "helium flash" a star like the Sun will have a brief period of stability, fusing helium into carbon (and sometimes oxygen). During this brief stable stage, the star:_________a. Increases tremendously in luminosity.b. Gets to be even larger in diameter than it was as a red giant.c. Returns to the position on the H-R diagram that the star had in its main-sequence stage.d. Is able to fuse many of the heaviest elements (such as iron and gold) in its superhot core.e. None of the answers provided is the correct answer
Answer:
a. Increases tremendously in luminosity
Explanation:
The helium flash is a thermal nuclear fusion with large quantities of helium gas into carbon. During the red giant phase, the sun is predicted to have a flash 1.2 billion after it leaves the main sequence and this helium fusion cannot be produced by the low mass stars. The sun in this stage will burn out or run out of its fuel and eventually will lead to gravitational collapse. The star being to shrink in size and core starts to collapse.zeugen and yardang differences

A. Extrusive igneous rock
B. Sedimentary rock
C. Metamorphic rock
D. Intrusive igneous rock
Answer:
C. metamorphic rock
Explanation:
Although metamorphic rocks typically form deep in the planet's crust, they are often exposed on the surface of the Earth. This happens due to geologic uplift and the erosion of the rock and soil above them. At the surface, metamorphic rocks will be exposed to weathering processes and may break down into sediment. hope this helps you :)

Which situations describe increasing atmospheric stability (choose all that apply): Group of answer choices daytime solar heating of the surface increases surface temperatures cold air from land moves over a warm lake rising surface temperatures on a calm, sunny summer day environmental lapse rate increasing with time a North wind brings in cold air from Canada, lowering surface temperatures Surface air cools while air aloft warms
Answer:
daytime solar heating of the surface increases surface temperatures.
Explanation:
Atmospheric stability is the condition where the air is generally considered to be stable than earlier due to the certain changes that take place over the period of time which are associated with the weather and climatic variability. As the colder air mass is denser than the warmer and lighter air mass thus reverse in the condition leads to instability.If__________is added to the single cell model of global circulation, the single cell convection system becomes a three cell convection system.
Answer:
Thermal energy
Explanation:
The atmospheric circulation is a large system of movement of air along with the circulation of water and thermal energy is redistributed o the surface of the earth through this method. The three cells namely Hadley, Ferrel, and polar cells that exist in the northern and southern parts of the world are balanced by the high and low pressures. The latitudes of 30 to 35 degrees are the place of high pressure were they diverge form.What is the channel-tunnel called between Calais (France) and Dover (England)?

What major geographical advantage does agriculture in the Coastal South have over most other regions of North America
Answer:
The region is largely frost-free so many frost intolerant crops can be grown.
Explanation:
The Coastal South in North America consists of cities like Florida, Texas, and North Carolina. This region is known for the exceptional agriculture that occurs there. The nature of their soil is not the cause of this, rather it has a lot more to do with their climatic conditions which range from the time of the last frost in spring to the beginning of the next frost in fall. So, this allows for about nine months of intensive agriculture.
Frost is ice which is mostly seen on the surface of the soil. It is quite difficult for many plants to survive the harsh condition imposed by frost. So the lengthy number of days and months without frost in the Coastal South gives it a great advantage over compared to many other regions in North America.

Understanding how to recognize landslides and other styles of mass wasting is important for homeowners! An earthflow is best described as:
a. The movement of soil downslope along a planar surface of rupture
b. A non-cohesive soil flow made up of sand to boulder sized sediments that is triggered by intense rainfall or rapid snow melt
c. A cohesive soil flow made up of mostly fine grained sediments (e.g., silt, clay and sand) that is triggered by intense rainfall or rapid snow melt
d. A landslide induced by the liquefaction of sediment during an earthquake
e. a mass of rock dislodged from a steep slope that free falls, bounces or rolls downslope
f. The gradual movement of soil downslope over the course of years or even centuries
g. The rotational movement of soil downslope along a rotational surface of rupture
Answer:
b. A non-cohesive soil flow made up of sand to boulder sized sediments that is triggered by intense rainfall or rapid snow melt
Explanation:
Earth flow is characterized by fine grained particles which are usually in a downwards motion as a result of the impact of the forces of gravity and water sweeping through it.
It is also known as a non-cohesive soil flow made up of sand to boulder sized sediments that is triggered by intense rainfall or rapid snow melt.

Bioplastics made from corn grown using industrialized agricultural methods would have a smaller ecological footprint that bioplastics made from native prairie switchgrass.
A. True
B. False
Answer:
A this is true
Explanation:
i had to answer this question and i got it right
Bioplastics made from corn grown using industrialized agricultural methods would have a smaller ecological footprint that bioplastics made from native prairie switchgrass.
Thus, the correct option A.
What are Bioplastics?Plastics made from renewable biomass sources, such as plant fats and oils, maize starch, straw, woodchips, sawdust, and recovered food waste, are known as bioplastics.
Some bioplastics are made by processing polysaccharides (such as starch, cellulose, chitosan, and alginate) and proteins (such as soy protein, gluten, and gelatin) directly from natural biopolymers.
Other bioplastics are made chemically from sugar derivatives (such as lactic acid) and lipids (such as oils and fats) from either plants or animals, or biologically by fermentation of sugars or lipids.
Contrarily, conventional plastics like fossil-fuel plastics, often known as petro-based polymers, are made from natural gas or petroleum.
Bioplastics have the advantage of not requiring fossil fuel as a raw material, which is a limited and unevenly distributed resource with political and environmental implications.

The discontinuity separating the crust from the mantle is named as: A.Mohorovicic B.Conrad C.Reppetty D.Gutemberg
Answer:
A.mohorovic
Explanation:
The Mohorovičić discontinuity (/moʊhəˈroʊvɪtʃɪtʃ/ MOH-hə-ROH-vitch-itch, Croatian: [moxorôʋiːtʃitɕ]),[1] usually referred to as the Moho discontinuity or the Moho, is the boundary between the Earth's crust and the mantle. It is defined by the distinct change in velocity of seismological waves as they pass through changing densities of rock.[2]
The Moho lies almost entirely within the lithosphere.[3] Only beneath mid-ocean ridges does it define the lithosphere–asthenosphere boundary. The Mohorovičić discontinuity is 5 to 10 kilometres (3–6 mi) below the ocean floor, and 20 to 90 kilometres (10–60 mi) beneath typical continental crusts, with an average of 35 kilometres (22 mi).
Named after the pioneering Croatian seismologist Andrija Mohorovičić, the Moho separates both the oceanic crust and continental crust from underlying mantle. The Mohorovičić discontinuity was first identified in 1909 by Mohorovičić, when he observed that seismograms from shallow-focus earthquakes had two sets of P-waves and S-waves, one that followed a direct path near the Earth's surface and the other refracted by a high-velocity medium.[4]
