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
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.

what kind of plate boundary exists at the san andreas fault
The topography of an old subduction zone is disturbed by the San Andreas Fault, which is a component of a transform plate boundary.
The San Andreas Fault is thought to be the transform (strike-slip) border between two significant plates of the Earth's crust: the North American to the north and east and the Northern Pacific to the south and west.
The San Andreas is categorized as a strike-slip fault because the Northern Pacific plate is passing the North American plate laterally in a northerly manner.
Over the course of geologic time, the movement of the plates with respect to one another has averaged around 1 centimeter each year.
Large earthquakes that originate close to the surface occasionally occur along the fault and have been linked to tectonic action, notably the tragic 1906 earthquake in San Francisco.

The layer of the atmosphere that has the least molecules is?
Exosphere has the least number of molecules in the atmosphere. Its thickness is between 1000 km to 10,000 km above the earth's surface. The phenomenon of weather and all the satellites are there.
The air or gaseous envelope that surrounds Earth and provides both protection and support for life is known as the atmosphere. Since it is densest there, the majority of our atmosphere is found nearby.
It consists of main four separate layers:
Troposphere: The troposphere's temperature is highest close to the planet's surface and drops with height. Its thickness is up to 10 km.
Stratosphere: The temperature in the stratosphere rises with height. It ranges in thickness from 10 to 50 km.
Mesosphere: Temperatures in the mesosphere decrease with altitude. Its thickness is between 50 to 90 km
Thermosphere: The density of molecules is so low in the thermosphere that one gas molecule can go about 1 km before it collides with another molecule

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

what type of plate boundary creates continental mountains
Some of the biggest mountain ranges in the globe are the result of continent-to-continent collision. The tallest mountains in the world are the Himalayas.
Two continents are colliding as they create mountains. The continental lithosphere is quite thick and has a low density. The lithosphere of a continent cannot subduct. Therefore, when two continental plates meet, they simply crash into one another. Similar to what happens when you place your hands on opposite sides of a piece of paper and pull them together, this also occurs. The only direction the material can go is up Earthquakes and metamorphic rocks are produced as a result of the collision's extremely strong forces. But magma cannot penetrate the crust because it is too thick. Therefore, there are no volcanoes in the areas where two continents collide.

soil has a high clay content and is very durable and strong t or f
It is TRUE that Clay (fine-grained soil) or soil with a high clay percentage that possesses cohesive strength is referred to as cohesive soil.
Particles of the same kind, origin, and nature are drawn together by a cohesive soil's attraction properties. Cohesive soils are thus a subclass of soil that adhere to one another. The silts and clays, or fine-grained soils, are cohesive soils.
Cohesive soil that has been dampened becomes malleable and resists collapsing. Additionally, vertical side slopes can be used to mine it. Cohesive soil exhibits great cohesion when submerged and is challenging to separate when dry.
Clay is an extremely cohesive soil with very fine grains. Course-grained soils like sand and gravel have little cohesion and are frequently referred to as granular. Because clay particles are so minute and numerous, clay exhibits significant flexibility and cohesion qualities. The surface area for cohesive bonding activity is maximized as a result.

Geothermal power a method of energy conversion that uses the earth's internal thermal energy.
Heat generated by the Earth itself is known as geothermal energy. (Geo means "earth" and thermal means "heat" in Greek.) It is a renewable resource that can be harvested for human use.
The warmest place on Earth is its core, which is located 1,800 miles or 2,900 kilometers beneath the planet's crust. A little portion of the core's heat is produced by the friction and gravitational attraction that were established during Earth's formation more than 4 billion years ago. However, radioactive isotopes like potassium-40 and thorium-232 decay play a major role in the continuous creation of heat on Earth.
Isotopes are variations of an element's atom that have fewer or more neutrons than the standard form of the element's atom.
