If you look at the leftmost part of the graphic, it includes a time axis, where the top represents the most recent time and the bottom the earlier times, so just using this axis, we can see that the fossil A is the earliest, or the youngest, because it it the highest one. - This is the correct answer, fossil A.

Additionally, we could look at the periods - our fossil A is from the Jurassic period. we can compare it to the fossil B, which is from Permian period. Indeed, Jurassic is a younger age than Permian (or Devonian and Cambrian, the ages of C and D) - so this confirms that A is the best answer.

salantis [7]

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.

In which of the following areas would one likely find Aridisols? In which of the following areas would one likely find Aridisols

gregori [183]

Answer:

the U.S. southwest

Explanation:

Aridosols are desert soils, where plant diversity is very low and often nonexistent. These soils are formed in arid and semi-arid regions, such as those found in the Southwestern United States. These soils occur due to the insufficient amount of precipitation in the region, in addition, due to the low vegetation cover, the rain that falls in the region, manages to leach the soluble salts of the soil, allowing them to drain into the deeper layers of the soil, where they can form carbonate, gypsum or saliferous horizons.

How do the physical features of North America affect where people live?

Serggg [28]

A physical feature is the mountains, deserts, and lakes. It affects where people live because of the climate, food, and water available. For example, if you live in the mountains, than you must have more snow than someone who lives in the desert. People may not want to live there because of the cold, that is why many people do not live in the mountains.

Hope this helps! :)

Which of these statements about saltwater is correct?

Mrac [35]

I think one of the statement here is erroneously written since A and B is the same statement. It should be that one choice is that "<span>Saltwater freezes at a lower temperature" and this is the correct answer. Saltwater experiences a freezing point depression due to the salt in the solution.</span>
