The expansion of the universe after its origin takes place by a phenomenon called big bang theory.
The most popular theory for how the universe came into being is called the Big Bang Theory. Simply expressed, it states that the universe as we currently understand it originated from an unimaginably hot and dense single point and expanded over the course of 13.7 billion years, first at unfathomable speeds and subsequently at a more palpable rate. Since astronomers cannot now look back at the Big Bang directly, they must rely on mathematical models and formulas to understand this event.

One weather phenomenon which will always occur when flying across a front is a change in the.
A change in wind direction is a weather phenomenon that will always occur when flying across a front.
Wind direction is contingent upon the course from what or to which place it originates. For example, a boreal wind blows from northward to the west side when facing north. The wind is the flow of air that happens as it is fiery for one sun and so rises. Wind direction is calculated concerning valid northward (not compass point) and is reported from what or to which place the wind is tumbling.
On Earth, ordinary weather phenomenon involve wind, clouds, rain, snowstorm, fog, and dust storms. Less common occurrences contain everyday troubles to a degree whirlwinds, hurricanes, typhoons, and ice storms.

lava question 13 options: a) tends to be most hazardous when associated with basaltic eruptions. b) cools and hardens below the earth's surface. c) always has same chemical composition, whether it is rhyolite or basalt. d) is the most life-threatening volcanic product of any eruption.
The most dangerous lava is often found in basaltic eruptions. Here option A is the correct answer.
Less viscous and flowing explosively is basaltic lava. As a result, lave is often riskier when related to basaltic eruption.
The most frequent type of volcanism on Earth and planetary bodies are basaltic eruptions. The low viscosity of basaltic magmas prevents fragmentation and encourages effusive and lava-fountaining activity, yet basaltic eruptions can still be extremely explosive and dangerous.
The vicinity of the volcano may be subject to a number of dangers, including lava flows, pyroclastic flows, lahars, jökulhlaups, and landslides or debris avalanches. Additionally, dangers brought on by volcanic activity, such as tephra or ash falls, gas releases, and tsunamis, can have an impact on locations that are distant from the volcano.

Which directly contributed to soil erosion on the great plains in the 1930s?the homestead actrailroadsheavy rainsfarming.
Farming directly contributed to soil erosion on the great plains in the 1930s. When soil is removed from a location on the landscape, it is called soil erosion.
Wind and water are the two primary causes of soil erosion. Climate generally affects what kind of erosion takes place. Strong winds and a generally dry climate in the Great Plains contribute to the region's extensive wind erosion. For instance, on May 12, 1934, winds transported roughly 200 million tons of soil from the Southern Great Plains 1,500 miles to the Atlantic Ocean. Loose, finely divided, dry soil on a bare, smooth surface are the ideal circumstances for wind erosion.
Suspension, saltation, and surface creep are the three mechanisms by which wind erosion moves soil. Large distances can be covered by suspension of very small particles (less than 0.05 mm in diameter). When the wind speed is lowered or they are washed away by rain, the particles lose their suspension and fall to the ground.

is the European
Union a pro or a con for the people of Europe? WHY?
Answer:
For the people of Europe, it is a pro
The European Union creates an allied front against outside aggression.The past 50 years in Europe have been some of the most peaceful out of the last 1,000 years of history. There have been fewer wars fought on the continent then at any time since the reign of the Roman Empire over the region. The European Union creates stability because all of the nations belonging to the agreement (or NATO) work together for their mutual good. Although this does increase their operating costs because there are domestic and international governments which require funding, it makes everyone safer as well.Europe has always had to balance the extremes in the past, from economics to religion, and that has not always been successful. Now that everyone is in economic cooperation at some level, the EU makes the smaller countries become international competitors.
where is the earth's crust the thickest? a below the continents b beneath the oceans c below the equator d below the north pole
Answer: Below the continents
Explanation: The Earth's crust is the outermost layer of the Earth and is made up of solid rock. It is thickest below the continents, where it can be up to 100 km (62 miles) thick. Beneath the oceans, the Earth's crust is thinner, only about 5-10 km (3-6 miles) thick. The thickness of the crust does not vary significantly based on location relative to the equator or the north pole.

Deep-focus earthquakes that don't fit the pattern. Here option B is the correct answer.
Generally speaking, earthquakes deeper than 70 km are referred to as "deep-focus earthquakes." All earthquakes that occur deeper than 70 km are restricted to large lithosphere slabs that are sinking into the Earth's mantle. H.H. Turner of Oxford, England, discovered the proof for deep-focus earthquakes in 1922.
At convergent plate borders, when a thick oceanic plate collides with a less dense continental plate and falls beneath the latter, the deepest earthquakes take place inside the core of subducting slabs, oceanic plates that drop into the Earth's mantle.
Unfortunately, surface damage from earthquakes tends to increase with depth; intermediate and deep-focus earthquakes seldom cause significant damage.

which of the following tends to occur when an area experiences tectonic uplift in its headwater region? a. the stream will lose energy. b. the stream will begin to deposit more of its load. c. the channel will begin to erode downward at a faster rate. d. the amount of turbulence will decrease.
The channel will start to migrate downstream more quickly when tectonic uplift occurs in an area's headwater zone. Here option C is the correct answer.
Tributaries join the river as it travels downstream, increasing the amount of water, velocity, and consequently the erosive strength. As it moves downstream, this permits it to cut a deeper channel. Less vertical erosion occurs as the channel widens and the gradient softens downstream.
Downstream, a stream's velocity often rises. Gravity, the absence of bed roughness, and an increase in the volume of water from the entrance of tributaries all contribute to enhance velocity as the gradient (slope) of the stream normally lowers.

the gravitational field strenght on the moon is 1.63n/kg. if a rock on the moon weights 2000n, how much does the same rock weigh on the earth?
Newtons per kilogram (N/kg) is used to measure the gravitational field strength (g). At or near the surface, the gravitational field strength of the Earth is 10 N/kg. This implies that an item will experience 10 N of force for every kilogram of mass.
The weight of an object is smaller if the gravitational field is weaker. The Moon, for instance, has a gravitational field that is 1.6 N/kg strong. This indicates that an object will encounter 1.6 N of force for every kilogram of mass. An astronaut will therefore be lighter on the Moon than they are on Earth.
Weight is the gravitational force exerted on an object; it is measured in newtons (N) and is directed toward the gravitational field's center. A spring balance, which is frequently referred to as a newton meter and is calibrated in Newton, can be used to determine an object's weight.
