Science Test
| Question | Answer |
|---|---|
| amber | hardened tree sap, often a source of insect fossils |
| cast | formed or shaped within a mold |
| earthquake | a movement or vibration in Earth |
| erratics | isolated boulders left behind by a glacier |
| fault | a break in Earth's outer layewr caused by the movement of rocks |
| glacier | a large mass of snow and ice that moves over land |
| horizon | a layer of soil that is different from the layers above and below it |
| humus | left over decomposed plant and animal matter |
| igneous rock | fire made rock formed from hot, molten rock material |
| imprint | a fossil created by a print or impression |
| metamorphic rock | rock that has been changed by heat, by pressure, or by both |
| mineral | a naturally occurring substance that is neither plant nor animal |
| mold | a hollow fossil form clearly showing the outside features of the organism |
| moraine | rock debris carried and deposited by a glacier |
| outwash plains | gravel, sand, and clay carried from glaciers by melting water and streams |
| permeability | the rate at which water can pass through porous material |
| relative age | the age of something compared with the age of another thing |
| rock cycle | a process by which rocks are changed from one type into another |
| sedimentary rock | rock formed when bits or layers of rocks are cemented together |
| soil profile | a vertical section of soil from the surface down to bedrock |
| terminus | the end or outer margin of a glacier |
| What are three causes of erosions? SA | wind, waves, glaciers |
| Know this equation - SA | soil=tiny rocks + minerals + humus + water + air |
| What are the three main groups of rocks? SA | igneous, sedimentary, and metamorphic |
| MC Rocks are made of | minerals, come in different shapes, colors, and sizes |
| MC Most fossils are found in | sedimentary rock and the layers help us to determine time order |
| MC Conglomerate | is pebbles and large grains of sand cemented together |
| MC Three properties used to identify minerals are | hardness, streak, and luster |
| MC The building blocks of rocks are | minerals |
| MC Luster | is the way light bounces off minerals |
| MC Relative age | is described using words like older, oldest, younger and youngest |
| MC Molten material below the Earth's surface is called | magma |
| MC The part of an animal's body most likely to become a fossil is | the bone, teeth, or a shell |
| MC Petrified means | "turned to stone". It happens when the once living parts of wood or bones are filled in by minerals. |
| MC A place in which animals got stuck and their bones were preseved as the material around them hardened is a | tar pit |
| MC The solid rock that maked up the Earth's outermost layer is the | crust |
| MC The layer below the crust is the | mantle |
| MC A liquid layer of Earth lying below the mantle is the | outer core |
| MC A sphere of solid material at Earths center is the | inner core |
| MC The solid rock layer which is broken apart into small rock pieces and minerals to form soil is called | bedrock |
| MC The top layer of soil that is rich in humus and minerals is called | topsoil |
| MC The space between soil particles is called | pore space |
| MC It takes about 100-1000 years for | an inch of topsoil to form. |
| MC Energy released as vibrations caused by rocks along fault lines moving and breaking are called | seismic waves |
| MC Seismic waves travel | in all directions |
| MC Scientists study earthquakes so they can | learn about the inside of Earth and to predict when they will happen. |
| MC Glaciers form when | more snow falls in winter than melts in the summer |
| MC Glaciers move | when the glacier beigns to melt and the water runs downhill. |
| MC Glacier till is | an unsorted mixture of rock materials deposited as a glacier melts |
| MC Glaciers have changed the Earth by | flattening and rounding the land and creating valleys |
