LESSON 1. What are the properties of water? Choose the correct answer: Water is a ____________ with unique properties. process
#substance = = = = molecules = = = = water flows + + + + Choose the correct answer: It plays an important part in the ________ that occur on the Earth’s surface. # process ==== substance ==== molecules ==== water flows ++++ 3.Water is made up of _____________. process ==== substance ==== # molecules ==== water flows ++++ 4.Each molecule of water is made up of one atom of _________ and two atoms of __________. # oxygen/hydrogen ==== substance/ hydrogen ==== oxygen/molecules ==== hydrogen/oxygen ++++ 5.At room temperature the molecules can move about freely: ___________. process ==== substance ==== # molecules ==== water flows ++++ 6. A powerful solvent. It dissolves many components of __________. # rock
substance ==== molecules ==== water flows ++++ 7. When water evaporates, it leaves deposits of ______________. process of salts ==== substance of mineral ==== molecules of mineral salts ==== # mineral salts ++++ 8. Absorbs heat. Water moderates the Earth’s climate by absorbing heat in _____ and emitting heat in ______. winter/summer ==== # summer/winter ==== spring/autum ==== autumn/spring ++++ 9. Cohesion and adhesion. Water is attracted to water: this is called __________. Solvent
Absorb ==== # cohesion ==== adhesion ++++ Water sticks to itself, it can travel through _____ in plants to ______ food to the leaves. transport/vessels ==== vehicles/form ==== country/gather ==== # vessels/transport ++++ 11. Water transports ________ throughout the bodies of living things. rock
#substance ==== molecules ==== water flows ++++ 12. Water molecules are also attracted to other materials: this is called ___________. solvent ==== Absorb ==== cohesion ==== # adhesion ++++ 13. As a result, water wets surfaces such as _____ and ______. # soil/rock ==== rock/substance ==== soil/molecules ==== water/flows ++++ 14. When water freezes, it _____ or ______ in volume. dilates/rock ==== increases/dilates ==== # dilates/increases ==== water/ increases ++++ 15. As a result, the volume of ice is greater than the same mass of _________ form. # water in liquid ==== water substance ==== water molecules ==== water in flows ++++ ******
The water of the oceans and the air of the atmosphere combine to deliver enormous quantities of moisture to the landmasses in an unceasing system called the _____________. water in liquid ==== water cycle ==== water substance ==== # hydrologic cycle ++++ The ______________ could not take place if water could not change from the liquid state to the vapor state and back again to the liquid state. water in liquid ==== # hydrologic cycle ==== water substance ==== water cycle ++++ When the surface of the ______ is in contact with an air mass, evaporation takes place, and _______ state becomes part of the atmosphere. ocean/water in liquid ==== ocean/water cycle ==== # ocean/water in the vapor ==== hydrologic cycle ++++ __________ rates are higher where temperatures are high, and warm air can contain much more moisture than cold air can, so that air masses in equatorial zones are typically humid, whereas polar air masses are dry # Evaporation ==== Temperature ==== Moisture ==== Hydrologic cycle ++++ 5. Once the _______ has entered the air mass and the air continues its movement in the trades, westerly’s, or some other pressure system, it may reach a landmass and overspread it. water in liquid ==== water cycle ==== #water vapor ==== water system ++++ By various processes the ______ in the air now condenses and falls on the land as precipitation. evaporation ==== # temperature ==== # moisture ==== hydrologic cycle ++++ 7. On reaching the _____________, some of this precipitation evaporates back into the air again–from the leaves of vegetation, from the soil, and from the surfaces of lakes and rivers. # land surface ==== earth surface ==== water surface ==== ground surface ++++ 8. Part of it seeps into the soil to become ________, but much of this eventually drains into lakes and streams and even back into the ocean itself. land surface ==== # ground water ==== water surface ==== ground surface ++++ And part of the precipitation becomes runoff, flowing directly into ________ that carry it back to the ocean as well. land
ground ==== surfaces ==== # streams ++++ 10. As the _____________ back into the ocean it mixes with the passing current, and eventually it may evaporate back into the air again. # water drains ==== ground drains ==== water surfaces ==== streams ++++ 11. Then the whole _________________ is renewed. land system ==== drainage system ==== # circulation system ==== streams ++++ 12. In this way the hydrologic cycle serves as a giant, worldwide _______________ that brings life-giving water to even the deepest interiors of the continents. land system ==== drainage system ==== circulation system ==== #pumping system ++++ 13.The hydrologic cycle is a ____________, and it is difficult to measure its components. # global system ==== drainage system ==== circulation system ==== pumping system ++++ 14. When climate scientists began to record precipitation, _______, seepage in soils, runoff in streams, evaporation, and other measurable processes in various areas on land and sea. global ==== # humidity ==== circulation ==== seepage ++++ 15. They made an important discovery: some areas have what may be called a __________, others have a deficit. global warming ==== air humidity ==== # water surplus ==== water drains ++++ 15.This in itself is not surprising – the ________ and _______ give strong indications of this. # landscape/vegetation ==== drainage/system ==== circulation/air ====
++++ 16. But what was surprising was that large areas that would seem to ________ actually do not or have it only seasonally. # have a surplus ==== have a drainage ==== have a circulation ==== have a pumping system ++++ 17. This gave rise to the concept of _______, the annual (or seasonal) water budget of a locale. water drains ==== ground drains ==== water surfaces ==== # water balance ++++ 18. Equatorial zones are best supplied with water and have a favorable ______________. water drains ==== # water balance ==== water surfaces ==== ground drains ++++ 19. But moving north and south from the equatorial zone into the tropics, we find large areas between 10° and 40°______ that have a negative balance – and not just desert areas. attitude ==== institute ==== # latitude ==== grades *****
LESSON 7.
# Aquifer ==== Geology ==== Latitude ==== Grades ++++ 2. A rock _______ which will yield significant quantities of water has been defined as an aquifer. # formation or material ==== material or formation ==== gas or metal ==== grades or celsius ++++ 3. Probably ____ of all developed aquifers consist of unconsolidated rocks, chiefly gravel and sand. 60% ==== 70% ==== 80% ==== #90% ++++ The _______________ beds of these aquifers produce large quantities of water, most of which is replenished by seepage from streams into alluvial fans at mouths of mountain canyons. water and drains ==== # sand and gravel ==== water and sand ==== sand and streams Download 60.8 Kb.
