Explain this phenomenon b. - ANSWER✅electromagnetic waves from the Sun come in
contact with the pizza. it causes the particles to move faster. heating the pizza.
hows the Sun involved with the water cycle. - ANSWER✅- Sun transfers energy to the
water in lakes, ponds etc. Water then evaporates as water vapor and when the water
vapor condenses, it forms precipitation (rain), then falls back to the ground eventually
flowing back to the original source. aka the water cycle.
