<span>Our Earth is structured around the densities of the materials which make it up.One property of density is that it determines the way materials in a mixture are sorted. This property of matter results in the layering and structure of Earth's atmosphere, water, crust, and interior.</span>
Answer:
- the specific gravity of the block is 0.75
- the specific gravity of the solution is 1.5
Explanation:
Given the data in the question;
first we find the specific gravity of a block SGB
SGB = ( block vol below / total block vol ) × the specific gravity of water
we substitute
SG = ( 1.5 / (1.5 + 0.5 ) ) × 1
SG = ( 1.5 / (1.5 + 0.5 ) ) × 1
SG = (1.5 / 2) × 1
SG = 0.75
Therefore, the specific gravity of the block is 0.75
specific gravity of solution SG
SG = (total block vol / block below ) × SG
we substitute
SG = ( 2 / 1 ) × 0.75
SG = 2 × 0.75
SG = 1.5
Therefore, the specific gravity of the solution is 1.5
Answer/Explanation:
The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.
Earth's surface warms up in the sunlight. At night, Earth's surface cools, releasing heat back into the air. But some of the heat is trapped by the greenhouse gases in the atmosphere. That's what keeps our Earth a warm and cozy 58 degrees Fahrenheit (14 degrees Celsius), on average.
