Heating of the inner portions of Earth result from fusion of hydrogen atoms. - Answer✔False
Other than trace amounts of He, early planet Earth had no atmosphere at the time of its
formation. - Answer✔True
H in every drop of water, including that in you, formed only in the Big Bang. Most others
formed from fusion in stars or fusion in supernovae (dying exploding stars). - Answer✔True
The terrestrial planets, including Mercury, Venus, Earth and Mars, are enriched in iron,
magnesium, silicon, and oxygen relative to the larger more distant planets. - Answer✔True
A rock sample from Saturn, if brought back to Earth, would be much heavier than any common
Earth rock. - Answer✔False
The age of light coming to earth from the most distant regions of the universe dates back to about
13 to 14 b.y. ago, the estimated age of the "Big Bang". - Answer✔True
The universe is expanding today. - Answer✔True
The Solar System is expanding today. - Answer✔True
Water on planet Earth initially arrived from comets. - Answer✔True
Without radioactivity the Earth, would be a dead planet. - Answer✔True
Island arcs result from convergence of two ocean plates. - Answer✔True
Ocean crust is oldest at the ocean ridges and becomes progressively younger with distance from
the ridge. - Answer✔False
Subduction zone earthquakes range in depth from shallow at the trench to several hundred
kilometers beneath the overriding plate. - Answer✔True
The longest mountain range of the Earth is mostly underwater. - Answer✔True
Primary waves cause the first shaking in an earthquake. - Answer✔True
The greater the distance to an earthquake epicenter, the longer the time period between arrival of
primary and secondary waves. - Answer✔True

Convergence of two ocean plates leads to the construction of island arcs such as the Aleutians,
the Tonga Islands, and Japan. - Answer✔True
Most of the Earth's seafloor has been recycled back into the mantle. - Answer✔True
As early as 1911, Alfred Wegener presented ideas about sea floor spreading. - Answer✔Flase
Ocean crust is primarily comprised of basalt. - Answer✔True
Pahoehoe is a Hawaiian term applied to blocky basalt flows. - Answer✔False
The port town of St. Pierre, on the Caribbean Island of Martinique, was destroyed by a nuee
ardente. - Answer✔True

island arcs - Answer✔True
The Earth breathes in through its volcanoes and out through its oceans and plants. -
Answer✔False
Phaneritic rocks are volcanic in origin. - Answer✔False
A glassy, highly vesicular volcanic rock formed form rhyolitic magma and that floats on water is
pumice. - Answer✔True
Andesitic and rhyolitic eruptions tend to be explosive because of their gas content and high
viscosity. - Answer✔True
