3 $100 Question from H1 the average weather conditions in An area over a long period of time

4 $100 Answer from H1 Climate (Temperature)

5 $200 Question from H1 The height (typically measured in feet above sea level) to which something is elevated or to which it rises

6 $200 Answer from H1 Elevation

7 $300 Question from H1 The more _______ _____ of a rock that is exposed to weathering, the faster the rock will wear down.

8 $300 Answer from H1 Surface Area

9 $400 Question from H1 Rocks that are made of ______ minerals will weather faster than rocks that are made of _______ minerals.

10 $400 Answer from H1 Softer, harder

11 $500 Question from H1 A process by which softer, less- weather resistant rock wear away and leave harder, more weather- resistant rock is called…

12 $500 Answer from H1 Differential Weathering

13 $100 Question from H2 Rain, snow or sleet that contains a high concentration of acids (an agent of chemical weathering)

14 $100 Answer from H2 Acid Precipitation

15 $200 Question from H2 These are agents of chemical weathering (name three)

16 $200 Answer from H2 Water, weak acids/plant Acids, air

17 $300 Question from H2 What causes acid precipitation

18 $300 Answer from H2 The burning of fossil fuels

19 $400 Question from H2 a chemical reaction in which an element, such as iron, combines with oxygen to form an oxide. This form of chemical weathering forms rust.

20 $400 Answer from H2 Oxidation

21 $500 Question from H2 Another name for living things such as algae or fungus (which live on rocks) which produce acids that slowly break down rock.

22 $500 Answer from H2 Lichens

23 $100 Question from H3 The grinding and wearing away of rock surfaces through the mechanical actions of other rocks or sand particles

24 $100 Answer from H3 Abrasion

25 $200 Question from H3 These are agents of Mechanical (Physical) Weathering (list at least 4)

26 $200 Answer from H3 ice, wind, water, gravity, plants and animals

27 $300 Question from H3 An agent of mechanical weathering that causes rocks to fall (rock slide/landslide) causing abrasion as they hit each other

28 $300 Answer from H3 Gravity

29 $400 Question from H3 When water seeps into cracks during warm weather, temperatures drop, water freezes and expands pushing against the sides of the crack (pressure), widening the crack until the rock breaks up/apart

30 $400 Answer from H3 Ice Wedging

31 $500 Question from H3 Describes how a rock changes after it has been in a riverbed for a long time

32 $500 Answer from H3 the edges of the rock are worn away and its surface becomes smoother

33 $100 Question from H4 The process by which wind, water, ice or gravity transports soil and sediment from one location to another

34 $100 Answer from H4 Erosion

35 $200 Question from H4 The process in which material/minerals are laid down after being carried away

36 $200 Answer from H4 Deposition

37 $300 Question from H4 The process by which rock materials are broken down by the action of physical or chemical processes

38 $300 Answer from H4 Weathering

39 $400 Question from H4 What agent of weathering can weather rock mechanically and chemically?

40 $400 Answer from H4 Water

41 $500 Question from H4 Name four factors that affect how fast weathering happens

42 $500 Answer from H4 Temperature, moisture, Elevation and slope

43 $100 Question from H5 The roots of plants can Grow deep into cracks and cause Mechanical weathering

44 $100 Answer from H5 True

45 $200 Question from H5 Elevation and slope can affect How fast weathering occurs

46 $200 Answer from H5 True

47 $300 Question from H5 Rocks with very little surface area weather faster than rocks With a lot of surface area

48 $300 Answer from H5 False

49 $400 Question from H5 Temperature is a major factor In both chemical and mechanical weathering

50 $400 Answer from H5 True

51 $500 Question from H5 In chemical weathering, the chemical composition of A rock does NOT change.

52 $500 Answer from H5 False

53 Final Jeopardy Briefly, how are caves/caverns formed underground?

54 Final Jeopardy Answer Acid precipitation seeps into ground and dissolves Limestone
