you observe a periodic shift of a star's spectrum caused by a planet orbiting the star. if the spectrum is redshifted, the star is movingaway from earth, away from earth
It is true that the star is moving away from Earth when the spectrum is redshifted. In astronomy, this phenomenon is known as the Doppler effect.
Christian Doppler first measured the effect of motion on waves in 1842. Doppler then applied what he learned to all waves, including light waves, and pointed out that when a light source is approaching the observer, the light waves will be crowded more closely together and when it is receding from the observer, the light waves will spread out. This general principle is now known as the Doppler effect.
As wavelength decreases, the colors of the light shift toward the blue end of the spectrum: this is called a blueshift. On the other hand, when the wavelength gets longer and the source moves away from you, the change in colors is called a redshift.

if the foram-bearing limestone (caco3) rocks outside of gubbio, italy (elevation. 522 m (1,713 ft)) used to be seafloor sedimentary rocks, what dynamic earth process caused them to end up above sea level?
The land was raised by tectonic forces of the earth as a result of a dynamic process, raising it above sea level.
Land sinking refers to the downward shifting of segments of the Earth's surface, whereas uplift refers to the rising of portions of the Earth's surface.
When there are density discrepancies, gravitational force controls all tectonic processes. The extensive mantle circulation of the Earth would serve as an excellent illustration of this. Plate motion is also caused by fluctuations in lateral density close to the surface.
Both uplift and sinking may arise through plate tectonic motions, which include the formation of mountains, or from the gravitational adjustment of the Earth's crust as a consequence of the removal or addition of material, such as ice or sediment, which causes uplift or sinking.

Are extrusive rocks associated with dome mountains?
Answer:
Hey there!
Explanation:
This is your answer...
The rocks that make up the plutonic dome mountains are the extrusive Igneous rocks. This is because plutonic dome mountains are generated from magma that pulls overlying igneous rock upwards, where it solidifies and cools to form a dome shape.

The following describe climate models and how we best use them are We include both natural and human variables, They help demonstrate cause and effect.
The interactions of the major climate drivers, such as the atmosphere, oceans, land surface, and ice, are simulated by numerical climate models using quantitative methods. They are used for a number of things, including studying the dynamics of the climate system and making climate projections. Climate models can also be narratives that are largely descriptive of potential futures and qualitative (i.e., non-numerical) models.
Quantitative climate models account for the sun's incoming short-wave electromagnetic radiation, primarily visible and short-wave (near) infrared radiation, as well as the sun's emitted long-wave (far) infrared electromagnetic radiation. A change in temperature is the result of an imbalance.

If air is a fluid, why isn’t convection responsible for transferring heat to earth from the sun?.
Since there is no air in space, convection, which transfers heat from the sun to the planet, cannot explain the situation if the air is a liquid; instead, radiation is required.
The electromagnetic transport of heat energy over space is known as radiation. The majority of the electromagnetic energy that the sun emits and that reaches the earth is unseen. Only a tiny fraction is visible light.
Radiation carried by electromagnetic waves travels from the sun to Earth. Visible light and infrared light make up the majority of the energy that travels through the upper atmosphere and reaches Earth's surface.
Conduction is a type of heat transmission where the energy must be transferred through a medium. Heat transmission by conduction is not feasible since there is no medium separating the surface of the Earth from the Sun.

Which of the following can influence temperature?
A) position on a landmass
B) cloud cover
C) altitude
D) all of the above
The position on a landmass, cloud cover and altitude can influence temperature.
Temperature is a gauge for the particles' average kinetic energy, or "energy of motion," in a sample of interest. While in everyday life we typically represent temperature using the relative Celsius or Fahrenheit scales, in scientific work we frequently use the absolute Kelvin temperature scale for calculations.
Temperature can be affected by where you are in relation to a landmass. For instance, being close to the ocean usually has a moderating effect on temperature.Temperature can be impacted by cloud cover. The amount of sunlight that reaches the surface is decreased, for instance, by cloud cover's ability to reflect and absorb sunlight. Cooler temperatures are the result.Temperature is influenced by altitude. As altitude rises, for instance, temperature tends to drop.

ground-up limestone (caco3) is used as a gentle abrasive in some powdered cleansers. why is this a better choice than ground-up soda ash (na2co3)?
Ground up limestone (CaCO3) is used as a gentle abrasive in some powdered cleansers. This a better choice than ground up soda ash (Na2CO3), because CaCO, is not soluble in water.
Since limestone naturally contains calcium carbonate and magnesium carbonate, lime is a rock powder soil amendment used in gardening. A healthy lawn and a stronger foundation for plant growth can be achieved by adding lime to garden soil, which increases the alkalinity of acidic soil and adds plant nutrients and minerals.
Two types of lime that are frequently used in lawns and gardens are agricultural lime and dolomitic lime. Agricultural lime (also known as garden lime) is made of calcium carbonate, whereas dolomitic lime is made of dolomite, a rock that is related to limestone and contains both calcium and magnesium. These are not the same as quick lime, hydrated lime, or slaked lime, which are used for a variety of purposes, such as cooking and water treatment, but are not used in agriculture.

One point of light that is the blurred image of both stars is the the correct statement describing, what will you see if you look at them with a telescope that has an angular resolution of 0.5 arcsecond
The ability of any image-forming tool, such as an optical or radio telescope, a microscope, a camera, or an eye, to distinguish minute details of an object is known as angular resolution, and as such, it is a key factor in determining image resolution. It is employed in the study of light waves in optics, radio waves in antenna theory, and sound waves in acoustics.
When comparing objects (such a leg or hand) to dust or other particulates in a scanning field, the angular resolution is a crucial parameter to consider. Smaller objects can be "seen" with a lesser angular resolution since the measurement points are closer together. The more beams, the greater the safety quality, so the lower the angular resolution.

Hurricane season for the atlantic ocean lasts from june to november. Which factor makes an atlantic hurricane less likely to form during the month of march?.
The Atlantic Ocean's hurricane season runs from June to November. which decreases the likelihood of an Atlantic storm forming in March.
The ocean is cool. When a hurricane season crosses land, its wind speed decreases because it formed over sea. Each year, the Atlantic hurricane season is officially observed from June 1 to November 30. The National Hurricane Center selected this six-month span because, according to NOAA's Hurricane Research Division, it accounts for 97% of all Atlantic tropical storms and hurricanes. Hurricanes are fueled by thunderstorms and warm ocean waters. Hurricanes seasonfrequently begin as tropical waves, which are low pressure systems that pass over moist regions of the tropics and may intensify shower and thunderstorm activity.

Abiotic and biotic communities interact with one another to create an ecosystem, which is constantly changing. A climax community is what results from these changes, which eventually bring a community close to being in equilibrium with its surroundings.Ecological succession is the general term for the gradual and predictable changes in the species composition of a particular area.
