The Coeur d'Alene Mining District in Silver Valley, ID is known for its large lead deposits of the mineral galena (PbS). Galena is one of the few common minerals with a metallic luster that has a distinctive cleavage (cleavage is how a mineral breaks or parts along preexisting planes of weakness). Cleavage is described by the number of unique directions of cleavage planes and the angle between those planes. Which of the following best describes galena’s cleavage?
a. three directions at ~90°
b. three directions not at ~90°
c. two directions at ~90°
d. two directions not at ~90°
Answer:
a. three directions at ~90°
Explanation:
Galena is known for its presence in all types of rocks (igneous, metamorphic and sedimentary rocks). It is predominantly ore of lead which has a chemical configuration of PbS and lead sulfide. Also, newly severed chunks of galena display excellent cleavage in three directions at ninety degrees.
Hence, in this case, the correct answer is "galena’s cleavage is best described as three directions at ~90°"

Suppose a line segment whose endpoints are T(x1,y1) and U(x2,y2) is reflected over y=x to create T′U′− . The coordinates of the image are T′(−4, 3) and U'(1, 7) . What are the values of x1 , x2 , y1 , and y2 ?
Answer:
T'(3, -4) U'(7, 1)
Explanation:
(x, y) ---> (y, x)
T'(y1, x1) = (-4, 3) ----> T(3, -4)
U'(x2, y2)= (1, 7) -------> U(7,1)

The Sun's gravity, of the force, keeps the planets from floating off into space. Thus, option (b) is correct.
What is planet?
The term “planet” refers to a large celestial body that orbits around the sun, but the sun is a fixed point in place. The planets are different sizes, as smaller planets are Earth, Mercury, Mars, and Venus. The larger gas giant planets are Jupiter, Uranus, Neptune, and Saturn.
The Sun's gravity plays a major role in the planets' tendency to drift towards space. The orbits are established and maintained by the combined effects of the sun's gravity, that of the planets, and inertia. The Sun and Planets are separated by Gravity, yet are Pulled Together by it. The high level was caused by the heat of the sun. Principal cause: gravity.
As a result, the Sun's gravity, of the force, keeps the planets from floating off into space. Therefore, option (b) is correct.

processes such as wind and water.
A. erosion
B. plate tectonics
C. climate
D weather
Erosion is said to be a naturally occurring phenomenon where natural factors like water , wind or ice take away a part of land , soil and its nutrients by applying their force and pressure on the Earth's surface .
Erosion is the process through which the Earth's surface is eroded away by the action of natural forces like wind and water. As a result, answer option (A) is appropriate.
What is erosion?Erosion is the process through which surface forces (such wind or water flow) remove soil, rock, or dissolved material from one area of the Earth's crust and move it to another, where it is deposited. Weathering, which involves no movement, is different from erosion. Physical or mechanical erosion is the removal of rock or soil as clastic sediment, as opposed to chemical erosion, which is the dissolving of rock or soil in a given area. Eroded sediment or solutes can travel hundreds of meters or thousands of kilometers.
Rainfall, bedrock wear in rivers, coastal erosion by the sea and waves, glacial plucking, abrasion, and scour, areal flooding, wind abrasion, groundwater processes, and mass movement processes including landslides and debris flows in steep terrain are some of the agents of erosion.
Hence, option (A) is accurate.

Write a report of no less than 125 words comparing the report of the two spies returning from Jericho (Joshua 2:24) with the report of the other spies mentioned in Numbers 13:31-33. Explain who exercised faith and how we can apply this to our lives today.
Answer:
The spies returning from the City of Jericho acknowledged the problems, but had faith that God would prevail over the problems. The other spies were lacked faith in God and did not think He would help them.
When the spies returned from reconnoitering the land of Jericho, and brought back a number of items including honey and giant grapes so large they had to be carried by two men and hung on a pole, they concluded that the land does actually flow with milk and honey.
"We went to the land where you sent us. It truly flows with milk and honey, and this is its fruit." (Numbers 13:27)
The spies also deduced that the people who dwelt in the territory are very large and very strong. The cities enormous and heavily barricaded. They saw that the descendants of Anak lived there in the city.
"Nevertheless the people who dwell in the land are strong; the cities are fortified and very large; moreover we saw the descendants of Anak there. The Amalekites dwell in the land of the South; the Hittites, the Jebusites, and the Amorites dwell in the mountains; and the Canaanites dwell by the sea and along the banks of the Jordan."
(Numbers 28-29)
The people began grumbling and complaining. Caleb, who was one of two of the faithful spies, said: "Let us go up at once and take possession, for we are well able to overcome it."
The other ten replied by stating: "We are not able to go up against the people, for they are stronger than we."
Numbers 13: 32-33 goes on to say: “And they gave the children of Israel a bad report of the land which they had spied out, saying, "The land through which we have gone as spies is a land that devours its inhabitants, and all the people whom we saw in it are men of great stature.”
What the spies saw were giants (whom were descendants of Anak); they felt like mere grasshoppers in comparison to them.
The following day, the people had had enough and began calling for Joshua and Caleb to be replaced by a new leader, one that would take them back to Egypt.
Both Joshua and Caleb ripped their clothes in anguish and told the people:
"The land we passed through to spy out is an exceedingly good land. If the Lord delights in us, then He will bring us into this land and give it to us, 'a land which flows with milk and honey.' Only do not rebel against the Lord, nor fear the people of the land, for they are our bread; their protection has departed from them, and the Lord is with us. Do not fear them." And all the congregation said to stone them with stones. Now the glory of the Lord appeared in the tabernacle of meeting before all the children of Israel.
(Numbers 14:7-10).
Here is where the report of the spies ends since as God has now interceded.
Explanation: Joshua and Caleb both exercised faith by trusting in the Lord and not falling weak to the people who said terrible things about them and wanted to replace them with someone who would do what they wanted.
We can apply this to our lives today by continuing to have faith in God. To trust His ways and obey them.
According to the report of the spies according to the book of Joshua 2;24, we can see that Joshua and Caleb went to the city of Jericho to spy and assess the strength of the warriors and city there and find out how they can take the city.
However, in Numbers 13: 31-33, we can see that out of the twelve spies which were sent, only Joshua and Caleb said positive things, but the other ten brought back negative reports by saying that they could never take the city, that the men were like giants, while they were like ants.
The two people who expressed faith are:
Joshua CalebWe should always apply such faith in our lives and believe that no matter how tough the difficulty is, we can overcome it.

why monsoon important for south and south east asia
Answer:
The monsoons are important for South and Southeast Asia because they bring in a huge amount of rainfall.
Explanation:
The monsoons act in the western Pacific Ocean and in the Indian Ocean, thus influencing the land in these areas. There are two types of monsoons, one of them is dry, while one is wet. The wet monsoons often are in the spotlight, and with every right, as they bring in enormous amounts of rainfall.
South Asia and Southeast Asia are the most affected regions. When the wet monsoons are active, these two regions get unimaginable amounts of rainfall. The rainfall is high in some areas that they are among the ones that have the highest rate of precipitation in the world. The importance, of course, is the rainfall, as it manages to provide water for the majority of the year, the rivers and lakes gain a lot of water and their levels rise significantly, and this helps the people a lot, especially in agriculture.
