Definitions
Substance that does not conduct electricity very well.
What is Insulator?
What is caused by a large amount of electrical flow in the core of the earth?
What is the magnetic field?
The vast majority of water on earth is found where?
What is the ocean?
What causes wind?
The point at which the earth is farthest from the sun is called?
What is Aphelion?
Rock formed when chemical reactions cement sediments together, hardening them.
What is sedimentary rock?
Scientist separate the earth into five distinct sections:
atmosphere, crust , mantle, core, and?
If a lake has no outlets, does it contain saltwater or freshwater?
What is saltwater?
True or False:
Insolation stands for "Incoming Solar Reaction"
What is false:
Insolation stands for "Incoming Solar Radiation"
True or False:
The magnetic field is important to life on earth.
What is true?
Without the magnetic field, cosmic rays from the sun would hit the earth killing all life on the planet.
The way in which the rotation of the earth bends the path of winds, sea currents, and objects that fly through different latitudes.
What is Coriolis effect?
The main thing that scientist observe to learn about the makeup of the earth's interior?
What are seismic waves?
True or False:
Glaciers are formed with saltwater.
What is false?
Glaciers start on mountains as the result of snow that never completely melts in the summer. If enough snow piles up, the weight causes it to slide down the mountain as a glacier.
The three main factors that affect earth's weather are:
Uneven distribution of energy, water vapor in the atmosphere, and ?
What is thermal energy?
Responsible for most of the light and sound in a lightning bolt.
What is the return stroke?
The cooling of a gas that happens when the gas expands with no way of getting more energy.
What is Adiabatic cooling?
The theory that says that the motion of the core is due to temperature differences in the core and the rotation of the earth.
What is the dynamo theory?
True or False:
Since salt is accumulating in the ocean, the older the earth is, the saltier the ocean will be. Based on the salinity of the ocean today we can conclude that the earth is not billions of years old.
What is true?
Over a period of a couple of days, the clouds slowly build and then a gentle, long rain ensues that last less than a full day. What kind of front causes this weather?
What is a warm front?
Hypothetical supercontinent that might have existed in earth's past is called?
What is pangaea?
The point at which the earth is closest to the sun.
What is Perihelion?
The more scientifically sound theory that attempts to explain the earth's magnetic field.
What is rapid-decay theory?
Evaporation of water from plants is called?
What is transpiration?
Any kind of cloud pattern and resulting rain is indicative of a cold front, therefore temperatures should increase or decrease after rain?
What is decrease?
What kind of cloud is necessary for a tornado to form?
What is cumulonimbus?
