With the recent technologies and scientific innovations we have now on studying and providing detailed analyses of the polar ice cores, it is roughly estimated that we could profile the ancient climate the Earth had in a time period as early as 800,000 years in order to explain the most recent climate change.

The Rate of movement of the Pacific Plate will be 37.87cm per year.

Underneath the Pacific Ocean is an oceanic tectonic plate known as the Pacific Plate. It is the largest tectonic plate at 103 million km2. The Farallon, Phoenix, and Izanagi Plate triple junction are where the plate initially formed 190 million years ago.

From the information given, the following can be deduced:

Distance = 500 km = 50000000cm

Time = 1.32 million years = 1320000 years.

Therefore, the rate of plate movement will be (i.e. speed) :

(speed) = Distance / Time

(speed) =  50000000 / 1320000.

(speed) = 37.87 cm/yr

Which of the following statements is false, based on the chart above?
Alchen [17]
Ok I don't know what chart it is (that would really help) but the global population is around 7 billion not 80 million so unless the chart is from a long time ago (when the population was smaller) I'd go with B. The global population is about 80,000,000

Which best explains why this extrusive volcanic rock does not have visible crystals
GalinKa [24]
Extrusive volcanic rocks are formed on the surface of the earth and cool relatively quickly from lava erupted from a volcano. The rapid cooling of lava on the surface does not allow for visible crystals to form. The crystals are minute and most can only be seen under a microscope. Basalt is an example of an extrusive igneous rock.

Intrusive igneous rocks are formed when magma cools within the crust. This magma cools slowly and so crystals develop in these rocks. Granite is an intrusive igneous rock.
