History of the Earth Crossword

states that layers of sediment were originally deposited horizontally under the action of gravity
gas in the geologic rock record, surfaces of contact between older rocks and younger sedimentary rocks, formed due to erosion or lack of sediment deposition over extended periods of time
any undisturbed sequence of rocks deposited in layers, the youngest layer is on top and the oldest on bottom, each layer being younger than the one beneath it and older than the one above it
areas of rock that move slowly upwards, pushed up by pressure of the rocks forming underneath, associated with earthquakes and mountain building
process used to arrange geological events, and the rocks they leave behind, in a sequence
a fossil that is useful for dating and correlating the strata in which it is found
the formation of new areas of oceanic crust, which occurs through the upwelling of magma at mid ocean ridges and its outward movement on either side
crack in the Earth’s crust
A long narrow ditch
a seafloor mountain system formed by plate tectonics
the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat
the sideways and downward movement of the edge of a plate of the earth's crust into the mantle beneath another plate also known as slab pull
relating to earthquakes or other vibrations of the earth and its crust.
the science that deals with the earth's physical structure and substance, its history, and the processes that act on it
The location where the earthquake begins. The ground ruptures at this spot, then seismic waves radiate outward in all directions
The point on the Earth's surface located directly above the focus of an earthquake
a hot spring in which water intermittently boils, sending a tall column of water and steam into the air
a principle of geology that states that the geologic feature which cuts another is the younger of the two features
the gradual movement of the continents across the earth's surface through geological time.
a portion of a continent that is submerged under an area of relatively shallow water
a fossil of a footprint, trail, burrow, or other trace of an animal rather than of the animal itself
