Consider the following astronomical statements. Classify each statement as either an observation, meaning something we have directly observed or measured, or an explanation, meaning something that we infer from observational or experimental evidence even though we cannot observe it directly.
[Observations]
- The Andromeda Galaxy is similar in structure to our own Milky Way
- All planets orbit the Sun in the same direction and nearly the same plane
- More distant galaxies are moving away from us faster than nearby galaxies
- Stars can shine brightly for billions of years
[Explanations]
- The universe is expanding because it began with a Big Bang
- The Andromeda and Milky Way galaxies formed in the same way
- The orderly orbits of planets arose from their formation in a rotating gas cloud
- Stars shine with energy generated by nuclear fusion in their cores

Answers

Answer 1

Consider the following astronomical statements, although it is crucial in science, the line between an observation and an explanation can occasionally be a little blurry.

Because we have observational methods that enable us to measure the ages of stars, we have classified the statement "Stars can shine brightly for billions of years" as an observation. In contrast, even though the statement "Stars shine with energy generated by nuclear fusion in their cores" is consistent with many observations, our conclusion that the energy source is fusion depends on our knowledge of the physics that should occur ins remember that our concepts of observation and justification might evolve over time.

For instance, although "Earth orbits the Sun" is something we today consider an established fact, it was once merely one possible explanation for what we view in the sky (and an alternate explanation of "everything orbits Earth" was favored for thousands of years). Due to the fact that both the Andromeda and Milky Way galaxies developed in a similar manner, their structures are similar.

Which of the following is the best example of physical weathering?a. the cracking of rock caused by the freezing and thawing of water.b. the transportation of sediment in a stream.c. the wearing of way of rock due to acid rain.d. the formation of a sandbar along the side of a stream.

Answers

The breaking of rock brought on by water freezing and thawing is the right response (a).

Physical weathering is the process through which rocks and other natural materials are destroyed physically. The process through which rocks are broken as a result of water freezing and thawing is an illustration of physical weathering.

Soil is created through the process of weathering. Once the rocks have been crushed into little pieces, the soil is created. There are various types of weathering, namely:

Physical weathering.

Chemical weathering.

Biological weathering.

It is a tropical cyclone that is formed in northwest pacific ocea affecting southeast asia,west philiphine sea and mostly japan​

Answers

You are referring to a typhoon, which is a type of tropical cyclone that is formed in the northwest Pacific Ocean and affects Southeast Asia, the Philippines, and Japan in particular.

Typhoons typically form along the Intertropical Convergence Zone (ITCZ), where warm moist air rises, resulting in large thunderstorms and winds that can reach up to 200 mph. The typhoon season in the region typically runs from May to November, with peak activity occurring in the months of August and September.

Once a tropical depression has formed, the Japan Meteorological Agency (JMA) will classify it as a typhoon if it has maximum sustained winds of at least 17 meters per second (about 33 mph). The JMA will then assign the storm a name, typically based on the phonetic alphabet.

The storm will then be monitored and tracked by the agency. Depending on its intensity, the JMA will issue warnings and advisories to the public, such as evacuation orders.

Since your question is not complete, here is the full task:

a. Strong winds

b.Torrential rain

c. Typhoon

d. Severe damage

a high point or ridge that determines the direction rivers flow

Answers

A divide is a high point or ridge that determines the direction rivers flow.

Rivers are often divided by high points or ridges that act as a boundary, determining the direction in which they flow.

These divides are important geographic features that mark the area that a river will flow through. They can also serve as boundaries between different watersheds or drainage basins, helping to define the geography of the area.

A divide is an elevated area of land that separates two drainage basins, often determining the direction in which rivers and streams flow.

This ridge or peak is typically the highest point in the surrounding area, and can be found in many regions throughout the world.

It is important to recognize the significance of divides, as they can influence the paths of water and the geology of the land.
