4th Grade Semester Exam Review

A student is studying the texture of the particles in different types of soil. She is comparing soils with clay, sand, gravel, and silt in order to determine which soil has the largest particles.

Which list below has the particles listed correctly in DECREASING order?

• Sand, gravel, clay, silt

• Gravel, sand , silt, clay

• Sand, gravel, silt, clay

• Gravel, sand, clay, silt

When identifying the texture of a soil, you are determining the-

• the type of rock underneath the soil

• the age of the soil

• the size of the grains in the soil

• the crops the soil supports

In some areas of Texas, solid layers of rock called bedrock are beneath a thin layer of soil.

Trees need to grow long, deep roots to get lots of water and hold the tree in place. Based on the information above, are the areas in Texas with bedrock beneath the soil a good place for trees to grow?

• Trees will grow well with bedrock because the roots can wrap around the rock.

• Trees will not grow well with bedrock because the roots will not grow deep.

• Trees will grow well because the roots can grow sideways instead of down.

• Trees will not grow well because the roots will break the rock.

During an investigation of soil samples, funnels are placed on top of glass beakers. Each funnel is then filled with different soil samples. Then, 100 mL of water is poured into each soil sample.

The purpose of this investigation is to determine —

• how much water is retained by each soil sample

• the mass of each soil sample

• the relative density of each soil sample

• which soil is darkest color

While observing soil samples, students noticed that water poured easily through sand, but it did not easily pour through the clay soil. What caused the clay soil to retain more water than the sand?

• The clay soil is darker color than the sand.

• Plants that grow in clay soil do not need a lot of water.

• Clay soil has large particles that keep water from flowing through.

• The soil particles in clay are small and packed closely together.

A class observed several soil samples. One sample was light-colored and had large grains that felt rough and scratchy. Water drained easily through this soil.

Which of the following plants would grow best in this soil?

• cactus

• ferns

• grass

• lettuce

Which statement best describes loamy soil?

• Fine, dry particles that allow water to move through easily.

• Loose, moist, black soil containing decaying leaves which allows some water to pass through it.

• Sticky, brown soil containing fine particles that doesn't let water move through it easily.

• Large, gritty, gray, white, and brown particles that allow water to move through it quickly.
