Rock Investigations

We have been busy studying the three groups of rocks: igneous, sedimentary, and metamorphic. Now that you have spent a week researching rocks, I want to know the following:

1. What type of rock is your favorite and why (igneous, metamorphic, or sedimentary)?

2. We know that plants need sunlight to make their food, but we haven’t studies the process yet. How do you think that plants use sunlight to make their food?

Also, please post an answer below:

  1. 1.My favorite kind of rock is Igneous because they came from valcanos
    2.Plants make there food by the sun shining on them then the sun shines on them so it gets in to the soil and makes food

  2. 1. My favorite rock was the sedimetary because the rock has different textures.
    2. It’s because of the brightness.

  3. 1. My favorite type of rock is metamorphic because they are made of two rocks pushing together.
    2. I think plants make food with the sun by having the sunlight go into the stem and spreading through the plant.

  4. 1. My favorite rock is the Medamorphic rock because two rocks create a new rock.

    2. I think plants make food using sunlight by soaking up the nutrients from the sun to create it.

  5. 1. My favorite rock is igneous because it is made out of volcanoes.
    2. Plants use sunlight to make food by the sunlight shining on it and the light puts nutrients in the plant.

  6. plants make their food by having some kind of process like the roots soak up the water and the plants take the sunlight as a light

  7. 1.My favorite rock is igneous because it is made out of lava.

    2.I think that they suck up nutrions from the soil and suck sunlight.Then use both to make food

  8. 1. My favorite is igenous because it comes from a vococaineno.2. I think plants make food with sunlight by sucking up all the nutreints up.

  9. I think plants make their food by soaking upwater with their roots and soak up sunlight with their leaves and mixing that to make there food.

  10. My favorite type of rock is igneous because igneous rocks are formed from volcanos.Plants make food when sunlight hits hydrogen and oxygen and makes glucose and glucose=plant food.

  11. 1. Sedementary because it is made by rocks smashing togather
    2.by smashing the water molocules with the power and letting the oxygin out as a wast and the carbon and hydrogin make glucose,a sugar that makes them green

  12. My faovrite type of rock is igneous because it came from different places.It can be used for rock climbing and gravestone.

  13. 1My favorite type of rock is a metamorphic because I like the way the they mostly look mostly spalrky.2They suck up nutrients from the soil.

  14. Plants use their roots to suck up water which go up xylem tubes in the tree, then the leaves breathe in carbon dioxide and sunlight which creates glucose and the plant eats it.

  15. plants make food by getting sunlight from the sun.Then they suck carbon dioxide and air.then.afterthat they get gluecose.they use roots to suck up water.My favorite rock is sedimentary because I think they are varible.

  16. My favorite type of rock is indgious. I like it because mine was an igneous. The trees roots suck up water and moves through the xylem and the plants leaves make carbin dixoide which the sun turns into glucose and the plant eats it eats it.

  17. my favorite rock is a igneous because it is formed by lava. plants make food by sucking up the water to xylem.now they breath in carbon dioxide.then they make glucose.

  18. metamorphic is my favrote rock becse it is a very butiful rock 2.plants use the roots to suck up the water pass the zylem up to the leaves to eat and it uses carbion dioxide to eat the food from the sunlight and water and the gluecoese helps it eat the food much betterandfaster

  19. my favrite rock is Ignas because some of the rocks are cool.This is the way plants make food.
    the roots suck up water and gose up xylem into leaves suck up carbendioxide and is mixed up
    with water to make glucose.

  20. roots suck up water and the xylem needs water and leaves let out corbondioxide every plant also needs sun light and glucose.

  21. My favorite rock is igneous because igneous rocks are made from volcanoes.

    2. How sunlight helps the plants is when the roots are in the soil the nurties helps the plant
    grow and the water goes up the xylem tubes and
    the carbon dioxide help the leaves grow . when the sunlight is faced at the leaves it makes glucose.

  22. 1.my faveret rock is ignious because its made of dried up lava
    2.i think sunlight helps plants grow by making the roots suck up water and the water goes through the xyem.then the xylem tubes leed up to the leaves.next the leaves breath out co2 and then make glucose.

  23. my favitoe rock metamorphic because it got some pretty good rocks. plants make their food in the sunlight and by doing that they suck in all the nuitints from the soil. and the roots suck up the water.and the plants make glucose and the plants need some space or they will die.

  24. I like igneous rocks because I like their colors and they are pretty to me. Plants roots sucks up the water to also make their food. leaves are green because there are glucose.

  25. my favorite rock is igneous because there are very small things you cant see. plants make food by sucking up the water with the roots,the water travels up the xylem tube,then the leaves suck up the carbon dioxide and makes glucose to eat.

  26. I think plants should get sunlight to get food.It needs roots,xylem,carbonidedioxide/leaves,sunlight, leaves.Thats why plants needs sunlight to make plants make food.

  27. 1 my favorite rock is a metamorphic because I like there textures and some are sparkly. 2Sunlighit comes to the hydrogen and the oxegen makes the glucose plant food.

  28. my favorite rock is igneous beause thay are interesting. plant mack food by . useing thar roots to suckup water into thar xylemtube.then it ues the leaves to
