Question

A. Lava destroys homes and farmland.
B.New species form at the wildlife preserve.
C. Many wildlife species become extinct.
D. Ash and dust fill the air and reduce sunlight.
E.Organisms and populations on the wildlife preserve die.

Answer 1

The answer is:

Lava destroys homes and farmland.

Ash and dust fill the air and reduce sunlight.

Organisms and populations on the wildlife preserve die.

When a volcano erupt, it will release magma that previously kept under the earth surface, which typically has the temperature of 700 Celcius. This would kill a lot of plants animals near the volcanoes. As it erupted, the volcano also release ash and dust that potentially caused breathing difficulties. As the dust rise up to the air, it would reduce sunlight and disrupt the photosynthetic process that being done by nearby palnts.

Answer 2

The correct answers are:

A. Lava destroys homes and farmland;

The lava flows can not really be stopped, so what they manage to reach will be destroyed, homes and farmlands on its way included.

D. Ash and dust fill the air and reduce sunlight;

A strong and violent volcanic eruption will release lot of ash and dust, and that will for sure affect the atmosphere, especially in close proximity to the volcano, which will reduce the sunlight, and make the climate colder.

E. Organisms and populations on the wildlife preserve die;

The lava flows, pyroclastic material, poisonous gases, ashes, will all contribute to death to every living organism that will not be able to escape on time, be it humans, animals, or plants, they will all die.
