Microscopy is not a method used to detect extrasolar planets.
<h3>Methods of detecting exoplanets:</h3>
Any planetary body beyond the solar system that typically orbits a star other than the Sun is referred to as an extrasolar planet, often known as an exoplanet. There are 3,779 planetary systems with 3,108 confirmed exoplanets as of 1 July 2022, 826 of which contain multiple planets. The Kepler space telescope was responsible for most of these discoveries.
Exoplanets contain elements that are comparable to those found in our solar system, but their compositions of those elements may vary. Iron or carbon may dominate some planets, whilst water or ice may rule others.
The following methods have at least once proved successful for discovering an extrasolar planet or detecting an already discovered planet:
- Radial velocity
- Transit photometry
- Ellipsoidal variations
- Pulsar timing
- Variable star timing
- Transit timing
- Transit duration variation
- Eclipsing binary minima timing
- Gravitational microlensing
- Direct imaging

#SPJ1
Is the movement and exchange of organic and inorganic matter back into the production of living matter.
Answer: spring and summer
Explanation:
Complete question:
Geologists are conducting a study on many layers of different types of rock in the Grand Canyon. These geologists will likely find ancient fossils that reveal the history of life near the Grand Canyon in
- igneous rock layers
-
layers of sedimentary rock
-
layers of volcanic rock.
-
metamorphic rock layers
Answer:
layers of sedimentary rock
Explanation:
Most rocks in the Grand Canyon are sedimentary rocks, formed while <em>sediments of sand and mud got deposited in thick layers and got compacted through the pass of time until becoming a rock</em>. Sedimentary rocks have been chronologically accumulating for years, reflecting the geological formation known as superposition. According to this sedimentary deposition, we can distinguish the older rocks located in the deepest areas from the younger rocks in more superficial layers.
As the sedimentary layers were deposited chronologically, they reflect the canyon history by keeping in each layer some of the forms of life that used to inhabit this area in the past. Such is the example of the superficial limestone stratum where many marine animal fossils are found, like clams, fish, and corals.
Answer:
oceanic crust and continental crust
