Flee or survive.
The ______ hypothesis has been developed by secular scientists to describe how our solar system came into existence.
Nebular
This we know for certain: no human was present to view the earth's _____.
Beginnings
Giant moving sections of the earth's crust are called ____.
Tectonic Plates
Secular geologists believe that Pangaea was
Made of many continental plates.
Why is it inaccurate to call a tsunami a tidal wave?
Tsunamis are caused by underwater earthquakes or other tectonic activity and are not related in any way to tides.
What are three main potential explanations for the origin of the earth? Which is the only one acceptable to a Christian?
The earth could have always existed. Or it could have formed naturally from preexisting materials. Or it could have been created supernaturally out of nothing. This final case is how the earth's creation is described in Genesis and is the only explanation acceptable to a Christian.
In relation to earthquakes, your textbook states that "… ground shaking alone seldom causes deaths." If this is true, then why do so many people die in large earthquakes?
Many deaths are caused by building collapse, especially in developing countries with low standards for construction. Fires ignited and fueled by broken electrical and gas lines also destroy property and kill many people. Disrupted water service may complicate firefighting. Earthquakes that occur underwater can trigger tsunamis that cause drowning. In mountain areas, an earthquake could trigger an avalanche or landslide, causing further loss of life.
Contrast the three main types of seismic waves. Include in your discussion their path of travel, speeds, relative intensities, and destructive power.
P and S waves are body waves—they move through the interior of the earth. P waves are fastest, have the smallest intensities, and can move through the core of the earth. S waves are slower but stronger than P waves. S waves cannot pass through the core. Surface waves (Rayleigh and Love waves) move at about the same speed as S waves and travel only along the earth's surface. They are the most destructive because they directly affect human structures.
A(n)_______ is a source of danger, while a(n) ______ is a possibility of injury or death to people and damage to property. We can reduce or even eliminate a(n) ______ but cannot change a(n) _______.
Hazard; risk; risk; hazard
