Where’s the tiles so that I can answer the question.
When its heated it expends
<h2>Solution:</h2><h3>Given data:</h3>
d= 20g/cm3
m= 10g
formula: d= m/v
By rearranging the formula according to our need:
v= m/d
by putting the values in the formula
v= 10g/20g/cm3
v= 0.5L
So, a rock that has a density of 20g/cm3 and a mass of 10 g would have the volume of 0.5L.
Answer:
D. None of the above
Explanation:
<u>Reason that Drastic Change in weather may cause mass extinction</u>
Weather plays an important role in the survivability & the growth/diminish of the population. For example, animals that need large amounts/bodies of water (for example fishes), will not survive when the area is hit with a heat wave & drought, which would cause fishes to surface, and die.
<u>Reason that Geological change would play a large role in mass extinctions</u>
While the Geography is constantly changing, large abrupt changes would cause a upheaval and may upset the population, leading to a depletion of resources or even a sudden destruction of part/all of the population. For example, an earthquake may kill large amounts of animals, and the destruction of the greenery in the area may severely limit the amount of food/decrease the primary consumer's populations, leading to a starvation.

Answer:
The cleaning up of Lake Washington didn't occur overnight. It started with the process of providing scientific information to the public and the public decided to take action.
The action was persistent and the results yielded took a long while to materialize properly.
Upon receipt of the information from scientists that a particular bacteria was responsible for damaging the ecology of the water body, the public resorted to conveying all effluents to a treatment plant rather than dump same in to the Lake.
