Answer:
Reflection: you look in the mirror. Refraction: You put a straw in a glass of water, and it looks like it broke. Absorption: If you have a black sweater and you wear it out in the cold, the black sweater is going to hold in heat better than a lighter sweater because the black sweater absorbs light .

Answer:
The correct option is;
Produces wind currents
Explanation:
The Earth's atmosphere which comprises the gases surrounding the Earth when heated up by the heating effect of the Sun creates winds such as land and sea breezes
The kind of forces that produce land and sea breezes results in wind patterns globally that affect climate. The curving masses of air due to the rotation of the Earth results in coriolis effect and trade winds that determines the cyclic (annual) seasons and weather.
Answer:
1.58gcm⁻³
Explanation:
Given parameters:
Volume of sample = 1.00L
Mass of sample = 1.58kg
unknown:
Density of the sample
Solution:
The density of a substance is expressed as its mass per unit volume.
The units of the parameters are given for volume as liters and for mass as kg.
We need to convert to cm³ for volume and into g for the mass:
1L = 1000cm³:
Therefore, the volume of the sample is 1000cm³
For the mass:
1kg = 1000g
1.58kg gives 1.58 x 1000g = 1580g
The density of the sample will be:
Density = 
Density = 
= 1.58gcm⁻³
