Answer:
Rocks and minerals are all around us! They help us to develop new technologies and are used in our everyday lives. Our use of rocks and minerals includes as building material, cosmetics, cars, roads, and appliances. In order maintain a healthy lifestyle and strengthen the body, humans need to consume minerals daily. Rocks and minerals play a valuable role in natural systems such as providing habitat like the cliffs at Grand Canyon National Park where endangered condors nest, or provide soil nutrients in Redwood where the tallest trees in the world grow.
Rocks and minerals are important for learning about earth materials, structure, and systems. Studying these natural objects incorporates an understanding of earth science, chemistry, physics, and math. The learner can walk away with an understanding of crystal geometry, the ability to visualize 3-D objects, or knowing rates of crystallization.

describing five effects of glaciers on both animal and human life.
Answer:
How do glaciers affect animals?
Their melting water flows into the soil which affects vegetation which acts as food for animals at lower altitudes, some of which are prey for other animals and so on. ... As glaciers melt large deposits of sediment are deposited in valleys below. This affects the local land and rivers and their existing ecosystems.
Without glaciers, what challenges could we face?
Answer:
If all the ice covering Antarctica , Greenland, and in mountain glaciers around the world were to melt, sea level would rise about 70 meters (230 feet). The ocean would cover all the coastal cities. And land area would shrink significantly. ... Scientists are studying exactly how ice caps disappear.

army private olivia dobbs observes a fighter plane known to be flying at a level elevation of 6.3 kilometers moving away from her. at one point she observes the plane at an angle of elevation of 49 degrees while one minute later the angle of elevation is 15 degrees. how fast is the plane flying in kilometers per hour?
Answer:
333.55 km/hr
Explanation:
Elevation = 6.3km
Angle of elevation = 49°
Current position
Using Pythagoras rule :
Tan θ = opposite / Adjacent
Tan 49 = x / 6.3
1.1503684 * 6.3 = x
x = 7.2473209
x = 7. 25 km
Position x, after 1 minute;
Tan θ = opposite / Adjacent
Tan 15 = x / 6.3
0.2679491 * 6.3 = x
x = 1.6880799
x = 7. 25 km
Difference in distance per minute :
(7.2473209 - 1.6880799) = 5.559241 km
Hence, distance covered per hour = (5.559241 * 60) = 333.55446 km
Speed = distance / time
Speed = 333.55446 km / 1 hr
Speed = 333.55 km /hr

why do tropical cyclone develop in late summer
Answer:
Wind factors, along with temperature and moisture factors, all play a role in tropical storm formation. Wind shear can tear disturbances apart before they strengthen, which gradually fades latter in the season, reaching a minimum in mid to late August. ... The statistical peak of hurricane season is September 10.
Explanation:
The tropical cyclones are known to develop in this period given that this when they have the most ingredient that are required in their formation.
What are tropical cyclones?These are terms for great natural disasters that occur in the forms of storms. Good examples of this is the hurricane.

A filter 30 feet (ft) long by 12 ft wide treats a flow of 4.4 million gallons per day (MGD). What is the filtration rate in gpm/ft2?1) 1.2 gpm/ft^2.
2) 81.8 gpm/ft^2.
3) 3,055.6 gpm/ft^2.
4) 8.5 gpm/ft^2.
Answer:
(4) 8.5 gpm/ft²
Explanation:
Given;
length of the filter, L = 30 ft
width of the filter, w = 12 ft
the filtration rate, Q = 4.4 x 10⁶ GPD
Area of the filter; A = 30 ft x 12 ft = 360 ft²
The filtration rate in gallon per minutes (gpm) is calculated as;
[tex]Q = 4.4 \times 10^6 \ (\frac{gallon}{day} \times \frac{1 \ day}{24 \ hours} \times \frac{1 \ hour}{60 \min} ) = 3,055.556 \ gpm[/tex]
The filtration rate in gallon per minutes per feet squared (gpm/ft²) is calculated as;
[tex]Q = \frac{3,055.556 \ gpm}{360 \ ft^2} = 8.49 \ \frac{gpm}{ft^2} \ = \ 8.5 \ \frac{gpm}{ft^2}[/tex]
Therefore, the filtration rate in gpm/ft² is 8.5 gpm/ft²
Artic anamals and climate change and the affects
Answer:
Explanation:The average temperature of the Arctic has increased 2.3°C since the 1970s. Ice dependent species such as narwhals, polar bears, and walruses are at increasing risk with shrinking sea ice cover. ... As the Arctic loses snow and ice, bare rock and water absorb more and more of the sun's energy, making it even warmer.
what does Europe have more of other continents
Europe's physical geography, environment and resources, and human geography can be considered separately. Europe's rich agricultural and industrial diversity has made the continent a centre of trade and commerce for centuries. It is centrally located between the two other “Old World” continents, Africa and Asia.
Europe did use to have lots of larger states and empires but most of them have broken up and are mostly arranged along ethnic lines. So there aren't many multi-ethnic states left in Europe anymore and a lot of these states were created due to wars.

Answer:
Greece started a democracy, and Rome started a republic. What political ideas came from ancient Greece and Rome? Balkan - Part of the Eastern Roman Empire :)
The political ideas come from ancient Greece and Rome are democracy, justice, and equality.
What government is there in Greece and Rome?Democracy in ancient Greece served as one of the first forms of self-rule government in the ancient world. The system and ideas employed by the ancient Greeks had profound influences on how democracy developed, and its impact on the formation of the U.S. government.
The ancient Greeks were the first to create a democracy. The word “democracy” comes from two Greek words that mean people and rule. Democracy is the idea that the citizens of a country should take an active role in the government of their country and manage it directly or through elected representatives. In addition, it supports the idea that the people can replace their government through peaceful transfers of power rather than violent uprising or revolution.
Thus, a key part of democracy is that the people have a voice.

Describe two ways in which oceanic-oceanic convergent boundaries differ from oceanic-continental boundaries. How are they similar?
Answer:
Explanation:
A)two ways that oceanic-oceanic convergent boundaries are different from oceanic-continental boundaries
1)The occurrence of Oceanic-oceanic convergence in the ocean are deep, when there is formation of trenches as a result of overlapping of one oceanic plate on another, then there will be scattering into small bits of the oceanic plate resulting in earthquake.
✓the nature as well as thickness of crust that exist in continental plates and oceanic plates: formation of oceanic plates is at divergent boundaries usually at ocean ridges. The Oceanic plates are thinner when compare with continental plates,
✓ Oceanic-continental convergence do cause mountain formation where there is overlapping of continental plate on
oceanic plate
B)How are they similar?
They are similar because convergence of each of them can catalyse formation of a volcano, also the descending of one slab on another is similar.
