Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.
How does a quickly changing coastline affect wildlife
Answer:
It can change the wildlife's habitat and which traits are favourable.
Explanation:
Ex: If there are less islands for seals to rest on, seals that can swim for longer periods of time will reproduce more.

A fish farmer intends to place a few cages along the coast of a large inland lake in Africa to grow a popular species of fish from North America. Which of the following is the most valid concern for people who practice traditional subsistence or commercial fishing in the area?
A.
If fish escape the cages, they may disrupt native species and reduce fishing production.
B.
The caged fish may consume all the nutrients in the lake water and cause a die-off.
C.
North American fish species produce excess nutrients that will create algae blooms.
D.
The local population will become accustomed to eating more fish, causing overfishing.
E.
The introduced fish will not be incorporated into local diets, and the new industry will fail.
Answer:
The answer is A.
Explanation:
In a new environment, a invasive species is not included in the natural niche yet and doesn't have any natural predators. In turn, this would cause the environment to bloom with these fish, along with different sub-species of this fish due to evolution and natural selection that would occur over the time it is an inhabitant.
First of all, some background knowledge. Over the years, people have attempted to create a state named “Lincoln” in areas of eastern Washington, the panhandle of Idaho and western Montana. The most recent attempt was in 2005. My question is why don’t they just rename Washington State or Washington DC? Instead of cutting out a portion of 3 states? Wouldn’t that be easier? I mean, they only want to create Lincoln State because they think that it is unfair that only one president gets a state.

How are the relative length of geologic time periods determined?
Answer:
Geologists have done the same thing to geologic time by dividing the Earth's history into Eras -- broad spans based on the general character of life that existed during these times -- and Periods -- shorter spans based partly on evidence of major disturbances of the Earth's crust.
Explanation:
Where are 90% of volcanoes located?
Answer:
The ring of fire
Explanation:
Seventy-five percent of Earth's volcanoes—more than 450 volcanoes—are located along the Ring of Fire. Ninety percent of Earth's earthquakes occur along its path, including the planet's most violent and dramatic seismic events. This is where I was supposed to be going for my vacation, but that plan failed because of a volcano that had erupted so badly.
native to a certain place.
Answer:
1 : one born or reared in a particular place. 2a : an original or indigenous inhabitant. b : something indigenous to a particular locality. 3 : a local resident especially : a person who has always lived in a place as distinguished from a visitor or a temporary resident.
Explanation:
In which location are earthquakes least likely to occur?
O A. Where tectonic plates are being pushed apart
O B. Along a fault line at a tectonic plate boundary
O C. At the center of a tectonic plate
O D. Where tectonic plates are being pushed together
At the center of a tectonic plate is the location are earthquakes least likely to occur. Hence, option C is correct.
What is a tectonic plate?Tectonic plates are massive pieces of the upper mantle and crust of the Earth. They are made up of both oceanic and continental crust. Earthquakes occur around mid-ocean ridges and important faults that create plate boundaries.
The heat generated by nuclear reactions taking place inside the planet's center causes the plates to move periodically toward and occasionally away from one another. This movement is also referred to as a tectonic shift.
There are four different types of boundaries between the tectonic plates as a result of their movement: divergent and convergent boundaries, transform fault boundaries, and plate boundary zones.
Thus, option C is correct.

When do stars, in their life cycles, fuse other elements together heavier than hydrogen or helium?
Answer:
As the main sequence star glows, hydrogen in its core is converted into helium by nuclear fusion. When the hydrogen supply in the core begins to run out, and the star is no longer generating heat by nuclear fusion, the core becomes unstable and contracts. The outer shell of the star, which is still mostly hydrogen, starts to expand. As it expands, it cools and glows red. The star has now reached the red giant phase. It is red because it is cooler than it was in the main sequence star stage and it is a giant because the outer shell has expanded outward. In the core of the red giant, helium fuses into carbon. All stars evolve the same way up to the red giant phase. The amount of mass a star has determines which of the following life cycle paths it will take from there.
diagram of the life cycles of low and high-mass stars
The life cycle of a low mass star (left oval) and a high mass star (right oval).
the different evolutionary paths low-mass stars (like our Sun) and high-mass stars take after the red giant phase. For low-mass stars (left hand side), after the helium has fused into carbon, the core collapses again. As the core collapses, the outer layers of the star are expelled. A planetary nebula is formed by the outer layers. The core remains as a white dwarf and eventually cools to become a black dwarf.

Why isn't glass considered a natural resource
Answer:
Glass is not considered a natural resource because it has to be made and can not be found already made before humans
Explanation:
Answer:
Cuz its almost always man-made
Explanation:
Believe it or not, glass is made from liquid sand. You can make glass by heating ordinary sand (which is mostly made of silicon dioxide) until it melts and turns into a liquid. You won't find that happening on your local beach: sand melts at an incredibly high temperature of 1700°C (3090°F) Although most people think of glass as a man-made material, it is found in many forms in the natural world. ... Scientists tell us that glass is a state of matter rather than a single material. Glass is created when molten material cools so rapidly that there is not enough time for a crystalline structure to form.
