3 0

<span>An indicator species is an organism whose presence, absence or abundance reflects a specific environmental condition. Indicator species can signal a change in the biological condition of a particular ecosystem, and thus may be used as a proxy to diagnose the health of an ecosystem. For example, plants or lichens sensitive to heavy metals or acids in precipitation may be indicators of air pollution. Indicator species can also reflect a unique set of environmental qualities or characteristics found in a specific place, such as a unique microclimate. </span>

The question is incomplete. The complete question is The Hawaiian Islands are composed of linear chains of which of these types of volcano?

A. Cinder cones B. Shield volcanoes C. Stratovolcanoes D. Lava domes

Rock Types 5. What is the difference between the two types of igneous rocks? A. The ages of the rocks. Intrusive rocks are always older

B. Extrusive rocks were formed in water, intrusive rocks were not

C. Intrusive rocks were formed in water, extrusive rocks were not

D. Intrusive rocks were formed in the Earth, extrusive rocks were not

Answer:

The answer to the first question is B (shield volcanoes) and the answer to the second question is D (Intrusive rocks were formed in the earth, extrusive rocks were not).

Explanation:

4) A shield volcano is a type of volcano in which the molten magma (lava) has low viscosity-this means they move easily. A shield volcano can be characterized by shallow sloping sides i.e. the slope are not steep. The most notable of the volcano chain in the Hawaiian island is the Kilauea mountain because it is the most active of them all and has an height of 1247 meters.

5) The differences between intrusive igneous rock and extrusive igneous rock includes cooling time, rock formation, mineral proportions and crystal size and texture. Intrusive rocks are formed beneath the earth surface, they have bigger crystals, takes a long time to solidify and has a coarse texture while extrusive rocks solidifies within a shorter period compared to the intrusive rock, has a fine texture and is formed on the surface of the earth.

A shield volcano is a wide volcano with shallowly-sloping sides. Shield volcanoes are formed by lava flows of low viscosity - lava that flows easily. ... The largest is Mauna Loa on the Big Island of Hawaii; all the volcanoes in the Hawaiian Islands are shield volcanoes.

Oceanic crust is it thin based on where it is

hichkok12 [17]

Answer:

Oceanic crust is created as magma rises to fill the gap between diverging tectonic plates and is consumed in subduction zones. It is geologically young, with a mean age of 60 Ma, and is thin, averaging 6.5 km in thickness. Oceanic crust consists almost exclusively of extrusive basalt and its intrusive equivalents.

Continental crust grows, recycles, and evolves by direct means of both, ________ and _________.

jasenka [17]

Answer: seafloor spreading and subduction magmatism

Explanation: Continental crust are termed as the crust destroyed by plate tectonic process mostly.Continental crust usually lies above sea level and because of this existence of land life to evolve from marine life possible.

Seafloor spreading is a type of process in which tectonic plate of Earth's lithosphere separate from one another. Subduction is also a process related with continental crust that occurs when tectonic plates collide with each other rather than getting apart.
