Biosphere, relatively thin life-supporting stratum of Earth's surface, extending from a few kilometres into the atmosphere to the deep-sea vents of the ocean.
The correct answer is C. It is so strict because a foreign species could compete with a native species and drive it to extinction.
The Hawaiian islands are one of the geographical isolated islands which faces the problem of the invasive species affecting the biodiversity of the island negatively.
The foreign species is equipped better to survive in the Hawaiian habitat and competes with the native species for the resources and food. The interaction and competition of the foreign species in the Hawaiian environment and habitat limits the resources for native species which increases the chance of the native species getting endangered.
The Hawaii Invasive Species Council along with other bodies such as department of agriculture, department of business and economic development, private and other government and non-government bodies have taken initiatives towards eradication of invasive species by strict laws.
Answer:
Yes. Hydropower, Wind Power, and just about any other alternative produces less CO2 than natural gas
Explanation:
Answer:
the magnetic direction of rocks along the surface of Earth and the age of rocks along the surface of Earth
Explanation:
The earth's magnetic field or geomagnetic field is believed to originate from the movement of molten iron and nickel in the outer core.
During a period in which the earth magnetic field is normal, crystallising magnetic minerals in magma records the orientation of the prevailing geomagnetic field. At other times when the field reverses and the magnetic field orientation changes, magnetic minerals in cooling magma stores this record.
To create a geomagnetic time scale, geologists can assign absolute ages to the records of these paleomagnetic anomalies which are the reversals. The rock is dated using radiometric techniques and each period of reversal is ascribed an absolute geologic age. Therefore, the magnetic direction of rocks along the surface of Earth and the age of rocks along the surface of Earth helps to build the geomagnetic time scale of the earth.
