4. It takes light from the Sun approximately 8.19 minutes to reach Earth, while it takes light from the star Ross 154 approximately 10 years to reach Earth. Why does it take
Ross 154's light so much longer to reach the Earth?
The mass of Ross 154 is much larger than the Sun
The Sun has a much higher luminosity than Ross 154
Ross 154 is much farther away from the Earth than the Sun
The Sun has a higher temperature than Ross 154
CLEAR ALL

the correct option is option d

the main thing i would use is bricks because if there is a hurricane, there is a great possibility for the house to still stand. and i would also use plexiglass windows instead of regular windows because plexiglass isn't prone to breaking.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
