Question 1

The theory of plate tectonics explains which geological phenomenon?

Accepted Answer

The movement of large sections of Earth's crust that causes earthquakes, volcanoes, and mountain formation

Answer

Plate tectonics describes how Earth's lithosphere is divided into moving plates whose interactions at boundaries cause major geological features and events.

Question 2

Photosynthesis in plants converts which inputs into glucose and oxygen?

Accepted Answer

Carbon dioxide and water, using sunlight energy

Answer

Photosynthesis uses light energy to convert CO₂ and H₂O into glucose (for energy storage) and releases O₂ as a byproduct.

Question 3

In astronomy, a 'light-year' is a unit measuring which quantity?

Accepted Answer

Distance — the distance light travels in one year

Answer

A light-year is a unit of distance equal to approximately 9.46 trillion kilometers, the distance light travels in one Earth year.

Question 4

The periodic table of elements organizes elements primarily according to which property?

Accepted Answer

Atomic number (number of protons) with elements arranged by recurring chemical properties

Answer

The periodic table arranges elements by increasing atomic number, with elements sharing chemical properties appearing in the same vertical groups.

Question 5

Which term describes the process by which radioactive atoms emit radiation and transform into different elements over time?

Accepted Answer

Radioactive decay

Answer

Radioactive decay is the spontaneous process by which unstable atomic nuclei lose energy by emitting radiation, transforming into more stable elements.
