TYPES OF ROCKS
WHAT IS SOIL?
TYPES OF SOIL
ROCK AND SOIL EXTRAS
100
Hard, non-living things found in the ground.
ROCKS
100
Hot, liquid rock found deep in the Earth.
MAGMA
100
The two things that the Earth's surface is made of.
SOIL AND ROCK
100
The 3 soil particles.
SAND, SILT, CLAY
100
Plants get these things from soil that they need to survive.
Nutrients, water, air, and a place to hold on so they don't fall over or fly away.
200
The way rock are different from each other.
SIZE, SHAPE, AND COLOR
200
The process of rocks recycling themselves.
THE ROCK CYCLE.
200
The 4 things soil is made up of.
WEATHERED ROCK, HUMUS, WATER, AIR
200
The largest sand particle, which does not hold water well, and is made of tiny pieces of rock.
SAND
200
Three things we get from plants.
Air, food, clothes, wood...
300
What rocks are made up of.
MINERALS
300
The process of rocks breaking down into smaller pieces by wind and rain.
WEATHERING
300
Why soil is important.
It is a place where organisms live. (plants, bugs, bacteria)
300
This smallest soil particle feels hard as stone when it is dry and does not allow water or air to pass through.
CLAY
300
The Earth would look like this if we had no weathering.
Covered with boulders.
400
The 3 sizes of rocks.
BOULDER, PEBBLE, and SAND
400
Three ways to compare rocks.
COLOR, SIZE, SHAPE, TEXTURE, HARDNESS, SHINEY/DULL, MASS...
400
What ORGANIC MATTER is.
Living and dead organisms like plants, bugs, leaves, and worms.
400
Loam.
A mix of sand, silt, and clay.
400
A diamond is a mineral which is formed from a very high amount of heat. So diamonds are probably found...
Deep in the Earth.
500
Three ways we use rocks.
Buildings, roads, floors, counters, sinks, jewelry...
500
The three types of rocks.
SEDIMENTARY, METAMORPHIC, IGNEOUS
500
This is what would happen if we did not have soil.
We would not have plants, which means we would not have oxygen, which means no living things could survive.
500
The BEST soil for growing plants is: a. sand b. loam c. clay d. silt WHY?
b. LOAM- It has a mixture of all three particles, so it can get the benefits of them all, like nutrients, minerals, and the right amount of water.
500
You have two different soils. You want to know which one plants would grow better in. You should ask: a. How much soil is there? b. How much did the soil cost? c. What is each soil made of?
