im stuck in some questions in my homework.. thnx in for ur help in advance!
1)What is the process where elements heavier than helium are formed?
2)What type of features are found at subduction zone(convergent boundaries)? ders 4 answers for it.. i already got mountains and volcanoes.
dats all guys thanks
perhaps these links will help you:

* Where Is It Found?: Provide a location on the Earth where this type of boundary is located.
* What are some features: Describe several geologic features associated with this type of boundary.
* What are some Connections to Other Disciplines: Give an example of something from Math, Language Arts, or Social Studies that helps describe the meaning of this type of boundary.
1) The process where elements heavier than helium are formed is called nucleosynthesis. Nucleosynthesis occurs in stars through two main mechanisms: nuclear fusion and stellar explosions.
To find the answer to this question, you can start by understanding the basic concept of nucleosynthesis. You can then research how stars create elements through nuclear fusion and stellar explosions. One reliable source of information is the Wikipedia page on "Big Bang nucleosynthesis," which provides an overview of the process.

2) At subduction zones, which are convergent boundaries, various features can be found. Some additional examples, beyond mountains and volcanoes, include:
a) Trenches: Subduction zones often include deep oceanic trenches, where one tectonic plate slides beneath another. These trenches can reach depths of more than 10 kilometers.
b) Earthquakes: Subduction zones are frequently associated with intense seismic activity, resulting in powerful earthquakes. These earthquakes occur due to the friction and stress accumulated as the plates interact.
c) Arcs: Subduction zones can give rise to volcanic arcs, which are curved chains of volcanic islands or mountains. These arcs form as magma rises from the mantle, generated by the subducted plate's melting.
d) Accretionary wedges: These are sedimentary deposits that accumulate near subduction zones. As the subducted plate slides beneath the overlying plate, sediments and rocks get scraped off the descending plate and accumulate in the wedge-shaped region.
To find these additional features at subduction zones, you can use the provided link to the Wikipedia page on "Subduction," which offers comprehensive information about subduction zones and the processes associated with them.
