ROCKS, MINERALS, SOIL, FOSSILS!

LET’S REVIEW.

If you were a tomato plant, what type of soil would you most likely want to grow in?

Sand Clay Loam Silt

From the surface, digging down, in what order would you find the three main categories of dirt here on earth.

Subsoil, topsoil, bedrock Topsoil, subsoil, bedrock Bedrock, topsoil, subsoil Topsoil, bedrock, subsoil

Which type of soil is made up of the smallest particles?

Sand Silt Clay

Which type of soil is made up of the largest particles?

Silt Sand Clay

Which type of soil is made up of dead plant and animal parts?

Sand Silt Clay Humus

Which layer of soil is the best to grow plants in?

Bedrock Subsoil Topsoil Sand

What kind of rock are you most likely to find fossils in?

Igneous Sedimentary Metamorphic granite

The process of rocks breaking apart in nature, over time, is called

Erosion Fossilization Weathering exploration

What are the three main types of rocks?

Granite, diamonds, mica Sandstone, limestone, feldspar Metamorphic, igneous, sedimentary Rocks, minerals, fossils

All rocks are

Made up of minerals Expensive when they are made into

jewelry Pretty Worth money

Minerals are best defined as

Rocks in the ground A solid, found in nature, that is not living Good to eat Things are different colors

What type of rock has been changed by pressure and temperature – or heat?

Sedimentary Metamorphic Igneous

What do we call the washing away and wearing away of soil over time – for example, in a flood?

Excessive rain Flooding Erosion metamorphosis

Sedimentary rock forms by which of the following processes?

Erosion Breaking apart Heating and hardening layering

Extinct means

No longer in existence – all gone forever Endangered Imaginary Very rare

What evidence lets us learn about things that are now extinct?

Fossils The internet Bill Nye the science guy Sponge Bob Square Pants

What are three attributes of rocks that scientists observe, in order to identify and classify rocks?

Green, red, blue Texture, feeling, smell Color, texture, hardness Harness, softness, chalkiness

What might you conclude if you found fossils of sea shells outside your school?

The beach is close by. Shells are so cool! The area at the school was underwater

millions of years ago. The area at the school was never near

water

A ditch on the playground, where the water runs from the pavement keeps getting deeper, and deeper and wider and wider each time it rains. What is causing this?

Kids are digging the dirt. Rain water is eroding the land near the

ditch. Bulldozers must be working near the

ditch. The ditch needs to be deeper.

Fossils are not found in metamorphic rock because

All metamorphic rock is under water. Animals don’t like metamorphic rock. Metamorphic rocks are never found. Metamorphic rocks are made with

pressure and heat, which would destroy any fossils.

If you found hot weather animal fossils in a place on earth that is now very cold and covered with ice, you might conclude

That the weather was much warmer there millions of years ago.

That the temperature was the same everywhere.

That the animals were lost. That polar bears are really cute.

The hardened remains of a living thing that lived long, long ago (plant or animal) are called

Erosion Fossils Rocks and minerals metamorphic
