Chemicals in water and rain can combine with rock and change it so that it crumbles and wears away. Gravity, flowing water, sand blown by wind, water freezing in a crack, and even the roots of trees can cause rocks to wear down or break apart over time. This process of rock breaking apart or being worn down is called this.
What is Weathering?
100
These are any nonliving solid that has a crystal form. They are formed in nature under the ground, in caves, and even in the air. There are over 4,700 different types found on Earth.
What is Minerals?
100
Geologist use a Streak Plate to help them identify minerals, since many minerals possess multiple types of this property that makes them appear different.
What is Color?
100
This is a solid in nature that is made of one or more minerals.
What is a Rock?
100
Soil, rocks and minerals that are mined, and fossil fuels such as coal, oil, and natural gas that are not easily replaced are all examples known as this.
What are Nonrenewable Resources?
200
Gravity, moving water, and even wind can perform the process of moving weathered rock from one place to another that is called this.
What is Erosion?
200
Geologists identify minerals according to these five properties.
What are color, hardness, cleavage, fracture, streak, and luster?
200
This property describes how a mineral reflects light.
What is Luster?
200
Pegmatite, Granite, Pumice, and Obsidian are examples of this kind of rock that can be formed when melted rock, or magma, cools and hardens slowly deep inside the earth, cools and hardens over a short period of time near the earth's surface, or cools and hardens very quickly on the earth's surface.
What is Igneous Rock?
200
Resources that can be replaced quickly such as air, water, wind, and sunlight are known as this.
What are Renewable Resources?
300
The process of dropping weathered rock by wind or moving water is known as this.
What is Deposition?
300
One property used to tell one mineral from another is luster. Luster describes how minerals reflect light. The three types of luster are described using these words:
What is earthy, metallic, and glassy?
300
The color left behind by a mineral when it is rubbed against a special plate is this mineral property. It is also what geologists call the plate.
What is Streak?
300
Seventy-five percent of rocks on the earth's surface are this type of rock. Sandstone, shale, and limestone are examples of this type of rock that is formed when pressure over time cements layers of sediment together below the earth's surface.
What is Sedimentary Rock?
300
Materials or things found naturally on Earth that humans use for a purpose are called this.
What are Natural Resources?
400
Very small pieces of rock, such as sand and silt that are moved by wind and water respectively are called this.
What is Sediment?
400
All minerals are made of particles that combine to form a shape that is repeated over and over again. It is this repeated structure that defines this.
What is Crystal?
400
A mineral that when broken has smooth, straight sides along the break exhibits this mineral property, and a mineral that does not break along smooth lines is said to exhibit this mineral property.
What is Cleavage and Fracture?
400
Slate, Schist, and Gneiss are examples of this type of rock that is formed when one type of rock is changed by heat and pressure deep inside the earth into another type of rock.
What is Metamorphic Rock?
400
Sunshine, water, phosphates, limestone, silica, and orange trees are some of the natural resouces found in this peninsula state.
What is Florida?
500
Landforms near the mouths of rivers that are created from sediment that piles up over time are called this; sand deposited by wind in a desert or water on or near a beach that is moved around over time by the wind into waves of sand are called this; and hills formed from sediment dropped off by a melting glacier are called this.
What are Deltas, Dunes, and Moraines.
500
Talc is a 1, Feldspar is a 6, and Diamonds are a 10 on the scale named after him that he developed in 1812 to compare the hardnesses of different metals.
Who is Friedrich Mohs?
500
Measured on the Mohs' Scale from Talc at the bottom to Diamond at the top, this property is a mineral's ability to scratch another mineral.
What is Hardness?
500
The continuous process in which one type of rock changes into another type through erosion and deposition, melting and cooling, and heat and pressure is known as this.
What is the Rock Cycle?
500
There are two ways to avoid using up resources too quickly. One way is by using resources wisely and less often and is known as this, and the second way is by reusing resources over and over again and is known as this.
What are Conserving and Recycling?
