1) Describe 3 pieces of evidence that Halley's Comet has for us to identify that it is indeed a comet

Answers

Answer 1

Answer:

Three evidences that Halley's Comet is considered a comet:

-Orbits the sun in 76 years.

- Found in the Kuiper Belt.

- Despite being a black body, it has a lot of shine.

Explanation:

Comets are bodies from outer space that are very easy to recognize.

They are balls of dust, rock and gas that have no rings or satellites and that "roam" through space.

Despite being dark and icy bodies, they seem to have a great shine when they get close to the sun due to the gas and dust they expel.

Another of its characteristics is that they take less than 200 years to orbit the Sun. Halley does it in 76 years, which qualifies it as a comet.

Finally, comets are found in the Kuiper belt, located beyond Neptune's orbit, and Halley is the best known of the comets found in this belt.

what creates Ocean currents​

Answers

Answer:

Upwelling and Downwelling

Explanation:

The Earth's oceans have differing temperatures and sediment levels.  Water with more sediment is usually colder, and thus is more dense and sinks.  Water with less sediment is usually warmer, and thus is less dense and floats.  Through a global conveyor belt of water, cold water starts at the the poles, cycles to the equator, where it is warmed, and then cycles back to the poles.

Ocean currents can be caused by wind or density differences

Follow these instructions, and fill in the table for different values of the diameter. Round your answers to the hundredths place. Move the slider to roll the circle. As you roll the circle, the circumference of the circle unfolds along the x-axis and the length of the circumference appears below. Once you have completely rolled out the circumference, fill in the table for the specific diameter you used. Roll the circle back to its original position. Change the diameter by moving the blue dot on the y-axis. Repeat these steps for each new diameter that you choose

Explanation:

Final answer:

The question involves a hands-on experiment to find the relationship between the diameter and circumference of a circle and visualize it on a graph, demonstrating the formula C = πD.

Explanation:

The question involves using the geometric properties of circles to determine the relationship between a circle's diameter and its circumference. When the circumference of the circle is completely rolled out, the length of this can be observed along a linear distance, which in essence is the circumference itself. From this experiment, one can deduce that the circumference (C) of a circle is directly proportional to its diameter (D), following the formula C = πD, where π (pi) is a constant approximately equal to 3.14159. By changing the diameter and recording the resulting circumference after rolling the circle, students are empirically finding values that support this formula. The data collected should then be plotted on a graph with the diameter on the x-axis and circumference on the y-axis to visualize this proportional relationship.

What evidence suggests that a mass extinction of the dinosaurs occurred at the end of the
Cretaceous Period?
A)
an absence of dinosaur fossils in Paleocene bedrock
B)
drawings of dinosaurs made by humans in caves during the Paleocene Epoch
C)
an abundance of dinosaur fossils in Early Cretaceous bedrock
D)
evolution of dinosaurs during the Late Cretaceous Epoch

Answers

Final answer:

The absence of dinosaur fossils in Paleocene bedrock suggests the mass extinction at the Cretaceous Period's end. Geological layers indicate an asteroid impact, supported by iridium concentration and the discovery of a related impact crater.

Explanation:

The evidence that suggests a mass extinction of the dinosaurs occurred at the end of the Cretaceous Period is A) an absence of dinosaur fossils in Paleocene bedrock.

The end-Cretaceous extinction event, which occurred about 65 million years ago, is one of the best-understood mass extinctions. This catastrophic event led to the disappearance of dinosaurs, except for a theropod clade that evolved into birds. The defining marker of this event is a high concentration of iridium in the geological layer separating the Cretaceous and Paleogene periods, consistent with the theorized impact of a large asteroid near the Yucatán Peninsula. This impact hypothesis is supported by the discovery of an appropriately aged impact crater and additional geological evidence. The boundary layer with increased iridium also coincides with the abrupt disappearance of dinosaur fossils.

C. Identify ONE spatial pattern shown on the map.

D. Describe the characteristic land use associated with the spatial pattern shown on the map.

E. Describe TWO geographic features not shown on the map that would help explain the patterns of dairy farming shown on the map.

Answers

A. Political boundary of the states of US.

B. Wisconsin

C. Dairy farms are located near great lakes.

D. Land is used for growth of corn and nutritious grass like alfa-lfa

E. Vegetation and Rainfall

Explanation:

A. The map consists of Political boundaries of the US states and the US mainland. In Geographical terminology, a political boundary refers to the imaginary line separating two or more than two political units. From the map, it is clear that most of the political boundaries of the US states are geometrical. They normally follow a particular line of longitude or line of latitude. E.g. State of Colorado is delimited by latitude 37° N to 41°N which defines its political boundary.

B. In the map, the state of Wisconsin has the highest concentration of the dairy farms when compared to the other states. The state is known to be amongst the leading dairy producer in the US and is nicknamed as “America’s Dairyland”. The high concentration of dairy farms in Wisconsin can be attributed to the proximity of the region to great lakes, optimum temperature and growing season, nutritious feed availability and superior breed of milch cattle.

C. One spatial pattern visible in the map is that most of the dairy farms are located in the vicinity of the great lakes along the North-Eastern part of the US. This high concentration of dairy farms in the region around Great lakes is due to the optimum temperate weather beneficial for dairy production, nutritious alfalfa grass and corn that is grown for feed purpose and success of the commercial dairy operation in these regions.

D. One characteristic land-use feature associated with the dairy farms is the use of large swaths of land to grow corn and nutritious alfalfa grass. Earlier, these lands were devoted to the cultivation of temperate wheat. However, the success of commercial dairy farming in the region has led to the introduction of extensive farming methods where large farms are devoted to corn and alfalfa production. Application of manures, usage of machines is very high and the overall yield of the farms is very high but yield per unit of land is low.

E. Two geographic features not shown on the map that corroborates to the above concentration pattern are-

Vegetation- Temperate grassland (Prairie) of these regions provides large and extensive ground for the cultivation of fodder grass. Prairie supports the cultivation of these grasses. Rainfall- These areas receive plenty of rainfall from humongous freshwater lakes in their vicinity. This rainfall proves crucial for cultivation for animal feeds.

The diameter of Earth is 12,756 km. How many times greater is the sun’s diameter than the diameter of Earth? Show the math.

Answers

Final answer:

The sun’s diameter is approximately 1.39 million kilometers, which is about 109 times greater than Earth’s diameter of 12,756 km.

Explanation:

The question asks how many times greater the sun’s diameter is than the diameter of Earth. Given that Earth's diameter is approximately 12,756 km, we can compare this to the sun's diameter. The sun’s true (linear) diameter is approximately 1.39 million kilometers, which is about 109 times the diameter of Earth.

To show the math, we perform a simple division:

Sun's diameter / Earth's diameter = 1,390,000 km / 12,756 km ≈ 109

Therefore, the sun's diameter is roughly 109 times greater than that of Earth.

Final answer:

Monsoon flooding affected the development of civilizations in the Indus River Valley by leading to drought conditions and population decline. The residents of the civilization heavily relied on the monsoon rains for agriculture.

Explanation:

The development of civilizations in the Indus River Valley was heavily influenced by monsoon flooding. The Indus Valley civilization, also known as the Harappan civilization, relied on the monsoon rains for agriculture. However, weakened monsoon rains led to drought conditions, which had a devastating effect on the population of the civilization.

The residents of the Indus Valley developed some systems of water supply, but their dependency on the monsoon rains made them vulnerable. As arid conditions increased, many people from the civilization began moving to other areas in search of better conditions.
