According to the Greek Earth-centered model of the universe, apparent retrograde motion

Answers

Answer 1

Answer:

The heliocentric model explains retrograde motion because Mars only appears to move backward as Earth passes it in its orbit around the Sun. ... To explain the retrograde motion of planets, it was suggested that the Earth and planets orbit around the Sun (heliocentric, or Sun-centered model).

Explanation:

Answer 2
Mark Brainliest please

Apparent retrograde motion
The word planet comes from the Greek 'planete' which means 'wandering', this because they were the only ones with the properties of modifying their position with respect to the fixed stars in the deep sky. For the Greeks, the sun, the moon, Mercury, Venus, Tuesday, Jupiter and Saturn were considered planets.

Answer and Explanation:
It occurred when the planet that was observed retreated in its orbit around the sun, it was giving an apparent image that once the body advanced in its orbit, it began to retreat and again to advance. At that time, there was no knowledge of the heliocentric system and that what was observed as a retrogression was a projection on the celestial plane of the planet, circling the sun.

Question 1 of 20
Match the water cycle element in column 1 with the characteristic in column

Answers

Hi. You have not presented the elements of the columns that the question refers to. This makes it impossible for this question to be answered. However, when searching for your question on the internet, I was able to find another question exactly like yours, which showed the following elements:

Column 1: A percipitation B transpriation C condensation D evaporation

Column 2: A Raising from plants B Forming droplets C Falling to Earth D Becoming solid

So I hope the answer below can help you:

Answer:

Falling to Earth: Precipitation.    

Raising from plants: Transpiration.  

Becoming solid: Deposition.  

Forming droplets: Condensation.

Explanation:

The water cycle is the continuous movement of water molecules through living beings and physical environments. This movement allows the water molecules to be used by living beings, but they become available again, which ensures that this liquid never runs out. During this cycle, precipitation refers to rain, that is, the fall of water from the sky, which can be in the form of liquid water, snow or hail. The water cycle also has a phase called transpiration, which is the water released by plant leaves, in the form of water vapor.

Another phase of the water cycle is called deposition, which occurs when water vapor in the atmosphere is frozen and becomes solid, forming ice.

There is also a phase called condensation, which occurs when water vapor present in the atmosphere is cooled to the point of becoming liquid water.

The pie chart tracks the percentage of renewable energy that’s being used in a particular community near the ocean. What are two advantages of using this type of graph for this particular data set?

Answers

Answer:

A. Readers can compare relative amounts of each type of renewable energy.

C. Readers get a quick visual on how each type of renewable energy contributes to the whole

Explanation:

Looking at the pie chart with each stated percentage consumption of each renewable energy sources, one can get a quick visual representation for easy understanding of how each contributes to the energy consumption that are renewable and also be able to tell how efficient each is.

For example, biomass has a percentage of 48%, which is the highest. Without knowing the actual amount consumed in kilojoules, we can visualize biomass as being the most dominant renewable energy source and that which will have the largest relative amount of renewable energy consumed compared to the rest.

Two advantages of using a pie chart can therefore can be summarized as:

A. Readers can compare relative amounts of each type of renewable energy.

C. Readers get a quick visual on how each type of renewable energy contributes to the whole

So, Rainfall in deserts is usually very intense.

When we use stratigraphy to classify sediments, we use a. the orientation of the magnetic field at the time it was deposited b. all of these things and anything else we can find to establish a sequence of formation c. the nature (properties) of the sediment d. the fossil content (if any)

Answers

Answer:

The correct answer is b. all of these things and anything else we can find to establish a sequence of formation

Explanation:

Stratigraphy is responsible for the study of rocks as bodies of three-dimensional extension to determine their extension and sequence; and as a consequence, determine the order and order and temporality of the events of the terrestrial history recorded in the sediments. Sedimentary rocks have accumulated an enormous amount of stratigraphic data that is observable on exposed surfaces (natural outcrops), excavations, quarries, mines, well drilling, etc., and it is up to the stratigraph to organize and integrate this accumulation of information. Stratigraphy records in rocks: forms, lithological compositions, physical and geochemical properties, original successions, age relationships, distribution and content of fossils; All these features serve to recognize and reconstruct geological events sequentially.

Once a terrestrial planet had formed from a large number of planetesimals, additional thermal energy from ________ could have melted it and allowed it to differentiate into a dense metallic core and a lower density crust.

Answers

Answer:

radioactive decay

Explanation:

Radioactive decay occurs as the nucleus of a set of unstable isotopes is disrupted as a result of great atomic instability. The nuclear breakdown releases a large amount of thermal energy, which has a very high temperature. An example of radioactive decay occurs when terrestrial planets form through a group of planetesimals. The thermal energy released in this process can even melt this planet.

Two identical homes are built on different earth materials. The first home is built on solid, hard metamorphic rock and the second home is built on soft sedimentary materials. Based on this information, which home will suffer more damage during an earthquake. Explain your conclusions and why the damage would be different.

Answers

Answer:

a. The second home built on soft sedimentary material will suffer more damage.

b. A large amplitude implies bigger waves and thus more damage than in the solid hard metamorphic rock.

c. The second home built on soft sedimentary material will suffer more damage than the first home is built on solid, hard metamorphic rock because of the rock type.

Explanation:

a. Based on this information, which home will suffer more damage during an earthquake.

The second home built on soft sedimentary material will suffer more damage.

b. Explain your conclusions

This is because earthquakes travel faster in hard material and thus have a smaller amplitude but move slower in soft material but have a large amplitude. A large amplitude implies bigger waves and thus more damage than in the solid hard metamorphic rock.

c. Why the damage would be different.

The damage would be different because waves with large amplitude move through the soft sedimentary rock while waves with smaller amplitude move through the hard metamorphic rock. A large amplitude implies a large wave and thus more damage than a smaller amplitude.

So, the second home built on soft sedimentary material will suffer more damage than the first home is built on solid, hard metamorphic rock because of the rock type.
