Answer:

Two possible reasons for the massive extinction at the end of the Paleozoic Era are an asteroid collision and massive volcanic eruptions.

Explanation:

The massive extinction that occurred at the end of the Paleozoic Era is the biggest extinction from what is known so far. The majority of the species died out, and whole families of animals and plants were wiped out of the face of the Earth. It was only small and highly adaptable organisms that managed to survive and give rise to the later life-forms.

The two possible reasons for this massive extinction are an asteroid impact and massive volcanic eruptions. An asteroid collision would have created drastic changes in a matter of minutes and hours, with effects lasting for a long period of time, thus eliminating the majority of the life. Massive volcanic eruptions, with the Siberian super-volcano being the prime candidate, may have caused enormous amounts of carbon dioxide and sulfur dioxide to end up in the atmosphere, thus rapidly changing the living conditions on the planet.

Gre4nikov [31]

Answer:

La Paz is a bit more densely populated than Lima, since the former has a population density slightly higher than this of latter.

Explanation:

In this case, we need to know the populations and occupied area of the city. By definition, population density is the ratio of the population of the city to the occupied area in the same location.

The required information is gathered below:

Population: 1.801 million (Metropolitan area)

Occupied area: 475 square kilometers.

Population density: 3792 inhabitants per square kilometer.

Lima (Perú)

Population: 9.674 million

Occupied area: 2672 square kilometers.

Population density: 3621 inhabitants per square kilometer.

In this case, La Paz is a bit more densely populated than Lima, since the former has a population density slightly higher than this of latter.

If immigration is 50, emigration is 20, the birth rate is 25, and the death rate is 10 (each per 1000 people), what is the perce
s2008m [1.1K]

Answer:

growth rate will be 4.5 %

So option A is correct option

Explanation:

We have given immigration = 50

Emigration = 20

Birth rate = 25

Death rate = 10

Each per 1000 people

We have to find the percentage growth rate of this country

Percentage growth is given by immigration - emigration + birth rate - death rate

So percentage growth rate = \frac{50-20+25-10}{1000}\times 100=4.5 %

So growth rate will be 4.5 %

So option A is correct option
