Answer: B
Explanation:
Explain how, in late winter, with snow covered ground and a southeasterly wind, advection fog could develop at Atlanta’s International Airport (located in the US Southeast, over 200 miles from the ocean) to create low visibility and flight delays.
Answer:
In late winter with snow covered ground and a southeasterly wind advection fog could develop at Atlanta’s International Airport (located in the US Southeast, over 200 miles from the ocean) to create low visibility and flight delays. This is because when warmer air from the ocean moves to the land surfaces where the Atlanta’s International Airport is built on, it comes in contact with it .
When the air cools, the temperature reduces to the dew point temperature. This allows for increase in saturation levels necessary in the production of fogs.

Answer:
Cinder Cone Volcanoes
these are the simplest type of volcano. They occur when particles and blobs of lava are ejected from a volcanic vent. The lava is blown violently into the air, and the pieces rain down around the vent. Over time, this builds up a circular or oval-shaped cone, with a bowl-shaped crater at the top. Cinder cone volcanoes rarely grow larger than about 1,000 feet above their surroundings.
Composite Volcanoes:
Composite volcanoes, or stratovolcanoes make up some of the world’s most memorable mountains: Mount Rainier, Mount Fuji, and Mount Cotopaxi, for example. These volcanoes have a conduit system inside them that channels magma from deep within the Earth to the surface. They can have clusters of vents, with lava breaking through walls, or issuing from fissures on the sides of the mountain. With all this material coming out, they can grow thousands of meters tall. As we’ve seen with the famous Mount Saint Helens, composite volcanoes can explode violently.
Shield Volcanoes:
These are large, broad volcanoes that look like shields from above – hence the name. The lava that pours out of shield volcanoes is thin, so it can travel for great distances down the shallow slopes of the volcano. These volcanos build up slowly over time, with hundreds of eruptions, creating many layers. They’re not likely to explode catastrophically. Perhaps the best known shield volcanoes are the ones that make up the Hawaiian Islands, especially Mauna Loa and Mauna Kea.
Lava Domes:
Volcanic or lava domes are created by small masses of lava which are too viscous (thick) to flow very far. Unlike shield volcanoes, with low-viscosity lava, the magma from volcanic domes just pile up over and around the vent. The dome grows by expansion of the lava within, and the mountain forms from material spilling off the sides of the growing dome. Lava domes can explode violently, releasing a huge amount of hot rock and ash.
Explanation:
which air mass is likely to form over Victoria Island in northern Canada and over Greenland in January and what would its characteristics be
Answer:
Continental polar air mass.
Explanation:
The northern parts of Canada are those areas that lie in the arctic circle and covers about 40% of Canada's land area. A total area of 3,535,263 km sq. The air is dry and cold throughout the region. In summer months the temperature is about 7.2 degrees. The continental polar air mass moves don from the polar regions and influences the temperatures of northern America.Suppose a future astronaut travels to a distance planet around a distant star. They collect rocks for dating the age of the planet and system. The astronaut compares the abundance of a certain radioactive element (half life of element = 500 million years) in the collected rocks to the abundance of the same element in a newly formed rock. They measure that there are 1/16th the number of radioactive atoms in the collected sample. How old is this planet?
a. 8 billion years old.
b. 4 billion years old.
c. 1 billion years old.
d. 2 billion years old.
e. 16 billion years old.
Answer:
The correct option is d
d. 2 billion years old.
Explanation:
The general formula to for the half life on an element is given as:
[tex]N(t)=N_o~ (\frac{1}{2})^{\frac{t}{t(1/2)}}[/tex]
Where
N(t) = Quantity of the substance remaining.
N(o) = Quantity of the substance which was initially present
t = time elapsed
t(1/2) = half life of the substance
In this question, we have to find t using the above formula, where
N(t) = 1/16
N(o) = 1
t(1/2) = 500
Substitute in the given formula:
[tex]1=\frac{1}{16}~ (\frac{1}{2})^{\frac{t}{500}}\\\text{Solve the equation for t}\\t = 2000[/tex]
Hence, the time planet has been into existence, or how old the planet is:
t = 2000 million years
or
t = 2 billion years
Match the definition to the appropriate term: A line in which two plates move in opposite directions from one another. Answer 1 Choose... A line in which one oceanic plate subducts underneath another oceanic plate. Answer 2 Choose... A line in which two plates slide horizontally past each other. Answer 3 Choose... A line in which an an oceanic plate subducts underneath a continental plate. Answer 4 Choose... A line at which a continental collision occurs.
Answers:
- A line in which two plates move in opposite directions from another is known as a divergent plate boundary.
- A line in which one oceanic plate subducts underneath another oceanic plate is called an ocean-ocean convergent plate boundary.
-A line in which two plates slide horizontally past each other is called a transform-fault boundary.
-A line in which an oceanic plate subducts underneath a continental plate is an ocean-continent convergence.
-A line at which a continental collision occurs is known as the continent-continent convergence boundary.

Imagine that you live in a coastal community in a region prone to earthquakes; you are a board member of your regional electrical utility. The utility is considering constructing a nuclear power plant 10 miles up the coast from your town. Some of your fellow citizens support the project because it will bring employment to the region and provide a carbon-free source of electricity. However, some residents fear a repeat of the events of 2011 in northeastern Japan if there should be a significant earthquake along one of the onshore or offshore faults.
Required:
List three specific pieces of information that you would insist on obtaining from geologists and other scientists before casting your vote on the project."
Answer:
1. Will power plant building be earthquake proof?
2. Will the chemicals placed in the power plant be enough secure that it does not leak or are prone to any explosion?
3. What are the chances of the site facing an earthquake?
Explanation:
1. Will power plant building be earthquake proof?
The building should be secure for the scientists working there and for the chemicals placed in there, if the site faces an earthquake an earthquake building may collapse and can result in explosions of the chemicals.
2. Will the chemicals placed in the power plant be enough secure that it does not leak or are prone to any explosion?
The chemicals placed in the power plant needs to be secured in a place where no unauthenticated entrance is allowed and if any earthquake hits the chemicals do not spill out or mix up which may result in explosions.
3. What are the chances of the site facing an earthquake?
Having a probability study before constructing a power plant is important, a complete chart should be made which shows the probability of this site hitting earthquake this study may be based on past results.
what has amazing mountain landscapes with rapidly melting glaciers, tropical savannas for world-class safaris, beaches, and even deserts.
Answer:
Tanzania is home to Mount Kilimanjaro which is the highest point in Africa.
Explanation:
However, the lower latitudes mean that glaciers and tropical savannas easily fuse. Tanzania is home to some of the most popular national parks and natural attractions in Africa, including the majestic Kilimanjaro Mountain.
Tanzania is a country in East Africa noted for its vast desert areas. They include the Everglades National Park plains, a safari hotbed inhabited by game "big five" (anteater, lion, cheetah, bull, wildebeest), and safari National Park, host to the tallest peak in Africa.
