Science Words Week 5

Front 1

Any method of measuring the age of an event or object in years.

Back 1

Absolute dating

Front 2

The process by which wind, water, ice, or gravity transports soil and sediment from one location to another.

Back 2

Erosion

Front 3

A natural, usually inorganic solid that has a characteristic chemical composition and an orderly internal structure.

Back 3

Mineral

Front 4

Rigid layer of Earth about 100 km thick, made of the crust and a part of the upper mantle.

Back 4

Lithosphere

Front 5

Any movement of matter that results from differences in density; may be vertical, circular, or cyclical. Currents in Earth’s mantle that transfers heat in Earth’s interior and is the driving force for plate tectonics.

Back 5

Convection currents

Front 6

Division of Earth’s history into time units based largely on the types of life-forms that lived only during certain periods

Back 6

geologic time scale

Front 7

Theory that Earth’s crust and upper mantle are broken into plates that float and move around on a plastic like layer of the mantle

Back 7

Plate tectonics

Front 8

The process in which material is laid down.

Back 8

Deposition

Front 9

Rock that forms when magma cools and solidifies

Back 9

Igneous rock

Front 10

Is used to arrange geological events, and the rocks they leave behind, in a sequence. The method of reading the order is called stratigraphy (layers of rock are called strata).this does not provide actual numerical dates for the rocks.

Back 10

Relative dating

Front 11

All of the nonliving things, living things, and processes that make up the planet Earth, including the geosphere, hydrosphere, the atmosphere, and the biosphere

Back 11

Earth system

Front 12

A rock that forms from other rocks as a result of intense heat, pressure, or chemical processes.

Back 12

Metamorphic rock

Front 13

Fragments of organic or inorganic material that are transported and deposited by wind, water, or ice and that accumulate in layers on Earth’s surface.

Back 13

Sediment
