Answer: Marie Skłodowska Curie (/ˈkjʊəri/ KEWR-ee;[3] French: [kyʁi]; Polish: [kʲiˈri]), born Maria Salomea Skłodowska (Polish: [ˈmarja salɔˈmɛa skwɔˈdɔfska]; 7 November 1867 – 4 July 1934), was a Polish and naturalized-French physicist and chemist who conducted pioneering research on radioactivity.
As part of the Curie family legacy of five Nobel Prizes, she was the first woman to win a Nobel Prize, the first person and the only woman to win the Nobel Prize twice, and the only person to win the Nobel Prize in two scientific fields. She was also the first woman to become a professor at the University of Paris.[4]
She was born in Warsaw, in what was then the Kingdom of Poland, part of the Russian Empire. She studied at Warsaw's clandestine Flying University and began her practical scientific training in Warsaw. In 1891, aged 24, she followed her elder sister Bronisława to study in Paris, where she earned her higher degrees and conducted her subsequent scientific work.
She shared the 1903 Nobel Prize in Physics with her husband Pierre Curie and physicist Henri Becquerel, for their pioneering work developing the theory of "radioactivity" (a term she coined).[5][6] Using techniques she invented for isolating radioactive isotopes, she won the 1911 Nobel Prize in Chemistry for the discovery of two elements, polonium and radium.

Explanation:
Answer:
If the two plates are of equal density, they usually push up against each other, forming a mountain chain. If they are of unequal density, one plate usually sinks beneath the other in a subduction zone.
Explanation:
Convergent boundaries is where two plates (a continental plate and the ocean floor) get "pushed together" by subduction. If they have the same density, they will be pushed up together creating a mountain (the Himalaya's mountain is a great example). If the plates have different density then the one with more density overlaps the other.
