How old is the Earth? 4600 years old 6000 years old 4.6 billion years old 4.6 million years old The lithosphere is broken into semi-rigid plates that can move. What drives this motion? gravity internal & external heat mostly internal heat magnetic field Which is a type of plate boundary? divergent transform convergent all of the preceding Most of Earth's extractable geologic resources are Limited in quantity and non-renewable Unlimited Copper and Gold Within the Mantle Visible from an airplane Global temperatures are thought to continue to rise in the near future. This may effect sea level in areas near the coast. True False Examples of natural disasters are Earthquakes Volcanoes Landslides Floods All of the Above. The Earth System that contains the solid rocky Earth is the Atmosphere Hydrosphere Biosphere Geosphere Duckosphere

Explanation / Answer

1) The Earth was formed 4.6 billion years ago. So age 4.6 billion years (C).

2) The motion of lithospheric plates is driven by Earth's internal heat (C).

3) All the three belongs to plate boundaries (D).

4) All Earth extractable mineral resources are limited. So these are non renewable (A).

5 )True. If the global temparatures are rised, the ice of the earth may be melted. So sea level may be raised. So the coastal areas may be effected due to raising sea level.
