Flashcards in Luci's Sceince Final Deck (32):
1

crust?

crust – the outermost solid layer of Earth, the part we live on

1

mantle?

mantle – the layer of Earth just below the crust, which contains most of Earth's mass

2

core?

core – the innermost layer of Earth

3

lithosphere?

lithosphere – the Earth's crust and the solid, upper part of the mantle

4

continental drift?

continental drift – the theory that the continents drifted apart in the past and continue to do so

5

plate techtonics?

plate tectonics – the theory that Earth's lithosphere is broken into about 20 moving plates

6

plate boundaries?

plate boundaries – areas where two plates meet

7

fault?

fault – a break in Earth's crust

8

focus?

focus – the underground location where the earthquake occurs

9

epicenter?

epicenter – the point on the Earth's surface directly above the focus

10

Richter Scale?

Richter Scale – is a measure of an earthquake's strength, goes from 1-10, each increase of 1 on the scale is an increase about 31 times of energy released.

11

mineral?

mineral – is a natural, nonliving solid with a definite chemical structure.

12

crystals?

crystals – a regular, repeating pattern in which particles of minerals are arranged

13

rock?

rock – is a solid, natural material made up of one or more minerals

14

sediments?

sedimentary rock – rock formed from layers of sediment that have been cemented together

15

igneous?

igneous rock – rock formed from lava that has cooled and hardened

16

metamorphic rock?

metamorphic rock – when heat, pressure, or chemical reactions change one type of rock into another type of rock

17

organic matter?

organic matter – any substance that is made of living or the remains of living things

18

humus?

humus – the organic part of soil

19

sediments?

sediments – solid particles carried from one place and dropped onto another place

20

weathering?

weathering – the process of breaking down rock into small pieces

21

mechanical weathering?

mechanical weathering – breaking down of rock, by wind, water, and ice

22

chemical weathering?

chemical weathering – a change in minerals as they react with substances in the environment, such as water or oxygen

23

erosion?

erosion – the process by which soil and sediments are transferred from one location to another, usually by wind, water, ice and gravity

24

renewable resources?

renewable resources – a resource that can be replaced through natural processes almost as fast as it can be used

25

nonrenewable resources?

nonrenewable resources – a resource that cannot be replaced as fast as it is used

26

fossil fuels?

fossil fuels – energy sources made from the remains of living organisms

27

geothermal energy?

geothermal energy – energy of the heat inside Earth

28

coal?

coal – a solid fossil fuel

29

petroleum?

petroleum – is a liquid fossil fuel

30

natural gas?

natural gas – is a fossil fuel that is a mixture of gases

31

acid precipitation?

acid precipitation – rain or snow that is more acidic than normal precipitation
