What tool is used to identify the elements present in a mystery chemical by comparing its emission spectra to known elements?

• Spectrometer

• Microscope

• Telescope

• Barometer

What evidence would you use to determine which elements are present in the mystery chemical X using the provided emission spectra?

• The matching pattern of colored lines at specific wavelengths

• The overall brightness of the spectra

• The temperature of the chemical

• The size of the sample

What is the pathway for starting at a nebula for a low-mass star?

• Nebula → Protostar → Main Sequence Star → Red Giant → Planetary Nebula → White Dwarf

• Nebula → Main Sequence Star → Supernova → Black Hole

• Nebula → Protostar → Red Supergiant → Neutron Star

• Nebula → White Dwarf → Main Sequence Star → Red Giant

What are the two possible pathways for high-mass stars?

• Main Sequence Star → Red Giant → White Dwarf or Black Dwarf

• Main Sequence Star → Red Supergiant → Supernova → Neutron Star or Black Hole

• Main Sequence Star → Planetary Nebula → White Dwarf

• Main Sequence Star → Red Giant → Supernova → White Dwarf

What are 4 possible theories as to how we got our moon?

• Fission, Capture, Co-formation, Giant Impact

• Erosion, Accretion, Subduction, Collision

• Evaporation, Condensation, Precipitation, Collection

• Expansion, Contraction, Rotation, Revolution

What seems to be the most likely way we got our Moon and what evidence supports that?

• The Moon formed from Earth's fission; evidence is similar density

• The Moon was captured by Earth's gravity; evidence is orbital path

• The Moon formed from a giant impact; evidence is similar composition to Earth's crust

• The Moon formed alongside Earth; evidence is identical core structure
