What is the correct equation for photosynthesis?

Answer: Carbon dioxide + Water → Glucose + Oxygen

The equation for photosynthesis is: Carbon dioxide + Water (+ light energy) → Glucose + Oxygen. Plants use CO₂ from air and H₂O from soil to make glucose, releasing O₂ as a by-product.

What type of rock can contain fossils?

Answer: Sedimentary

Fossils are found in sedimentary rock, which forms from layers of sediment (sand, mud, shells) that compress over millions of years. The soft layers preserve remains of organisms.

What is the unit of force?

Force is measured in Newtons (N), named after Sir Isaac Newton. A Newton is the amount of force needed to accelerate a 1 kg mass at 1 metre per second squared. Weight is also measured in Newtons.

What is the name for the process by which water moves from the sea to clouds to rain?

Answer: The water cycle (or hydrological cycle)

The water cycle (hydrological cycle) describes the continuous movement of water: evaporation from sea/land, condensation to form clouds, precipitation as rain or snow, and runoff back to the sea.

Which sense organ detects light and allows us to see?
