Size, or the diameter of its primary mirror or lens, is a telescope's most crucial characteristic. Larger telescopes can view fainter objects because they can gather more light. With a telescope only 4 to 6 inches in diameter, you can see quite a bit.
The telescope has changed in what ways?Sir Isaac Newton concluded that building a telescope using mirrors rather than lenses would be preferable after studying Kepler's work. Mirrors permit light to pass through them and reflect it, whereas lenses only permit light to pass through and bend (refract). In 1668, he created the very first practical reflecting telescope.
What modifications to telescopes have been made over time?Since its invention 400 years ago, the astronomy telescope has seen substantial development. From a small, manually aimed equipment for visual observations to a large, sophisticated, computer-controlled instrument with full digital output, the telescope has undergone significant transformation.
What are the two fundamental telescope models?Telescopes can be divided into two categories: refractors and reflectors. The type of telescope is determined by the objective, which is the portion of the telescope that collects light. A glass lens serves as the objective of a refractor telescope.

Choose the correct description of advantages gained if a planet can be detected by both methods.
If a planet can be found using both techniques, then we can determine its density, which is a sign of its makeup.
Which two techniques do scientists have at their disposal to look for planets?By employing Doppler spectroscopy and astrometry (SIM) data, it is feasible to search for any prospective giant planets that might also be present in the systems discovered by photometry.
What factors into a planet's density?Measureable characteristics of planets include their size, mass, and composition. The density of an object is dependent on its mass as well as its size (bigger things are not always more or less dense). The density of a planet depends on its make-up.
What two techniques can be combined to determine an exoplanet's density?Both the transit method and the radial-velocity method can be used to examine the same exoplanet in order to determine the planet's mass, as well as its density and most likely composition, because transiting exoplanets always orbit in orbital planes that are edge-on to Earth-based observers.

Which of the following processes resulted in the deformation of sedimentary units in the American West during the Jurassic Period?
subduction of the Farallon plate beneath the North American plate
The deformation of sedimentary strata in the American West during the Jurassic Period was caused by the Farallon plate subducting beneath the North American plate.
What purpose served the Farallon plate?About 100 million years ago, the Farallon oceanic plate was placed between the diverging Pacific & North American plates, which later united to form the San Andreas fault. The Farallon was subducted beneath North America and then plunged deep into the mantle when those plates clashed, causing a significant component of the structure to disappear.
When did the Farallon plate go under the ocean?50 million years ago, at the start of the series, the Farallon plate started to press against the North American continent, sinking beneath it and forming mountain ranges like the Rocky Mountains. The Farallon plate was subducting as a single unit along the entire length of North America, from Alaska down past Mexico.

ocean water is saltiest . group of answer choices in estuaries at the equator where there is high evaporation and low precipitation where there is a large amount of glacial melting where rains are the heaviest
Option (b), ocean water is the saltiest when there is little precipitation and a high rate of evaporation.
Is evaporation making the ocean saltier?The evaporation of ocean water and the expansion of sea ice both raise the salinity of the ocean. The constant intake of fresh water from rivers, the accumulation of rain and snow, and the melting of ice are all causes that counteract the "salinity rising" forces by reducing salinity.
In the saltiest regions of the ocean, there are the highest rates of evaporation or enormous amounts of water without a way to reach the ocean. The region around the Red Sea and Persian Gulf has the saltiest ocean water (around 40), which is a result of exceptionally high evaporation and little fresh water inflow.

Why does Florida have so many sinkhole lakes?
➡️Remember to mark me brainliest, please
Answer:
Florida has a high incidence of sinkhole lakes due to the geology of the state. Florida is located on a limestone plateau, which is a type of rock that is relatively porous and susceptible to dissolution by acidic water. As rainwater percolates through the ground, it can dissolve the limestone, creating underground cavities and channels.
When the roof of one of these underground cavities collapses, it can create a sinkhole, which is a depression or hole in the ground. If the sinkhole is filled with water, it can become a sinkhole lake.
Sinkhole lakes are common in Florida due to the state's humid subtropical climate, which results in high levels of rainfall. The state's flat terrain and relatively low elevation also contribute to the formation of sinkhole lakes.
Answer:
When water like rain flows through the porous limestone, it slowly dissolves forming sinkholes

Explanation:
which of the processes listed below would transform an exposure of granite in the mountains into sedimentary rocks?
The process that leads to the development of a sedimentary rock is the breakdown of rock into sediment.
Detrital rock is a type of sedimentary rock that develops at the Earth's surface or very close to it when sediment accumulates and crystallizes at temperatures typical of the surface (chemical rock). Although igneous and metamorphic rocks make up the majority of the crust overall, sedimentary rocks make up the majority of rocks that are exposed on the Earth's surface. Sedimentary rocks are produced by weathering pre-existing rocks, conveying the leftovers of that weathering, and depositing them. Numerous processes of physical disintegration and chemical degradation occur when rocks at the Earth's surface are exposed to the atmosphere (most commonly in the form of rainfall) and the hydrosphere. As a result of these actions, soil, unconsolidated rock debris, and materials dissolved in runoff and groundwater are formed.
