• Q1
Weathering is a process that helps make soil. All but one statement describes how rocks may be weathered. That is:
Rock pieces are moved from place to place.
Water fills tiny spaces inside a rock.
Plant rooks can grow between cracks in rocks.
Lichen chemically breaking down rocks.

How do waves change sand on a beach?
Divides beaches in half.
Increase the number of plants right on the shore.
Waves wash sand away and deposits in other places.
Builds sand dunes on the beach.

• Q3
Scientists have tracked the changes in this land for many years. Picture A shows how the land looked to start with. Many years later, the land looked like Picture B. What MOST LIKELY caused the change in the land?
Water cutting the rocks
earthquakes along the shore
a coastal glacier
wind blowing in circles

• Q4
A student blew out through a straw and directed his breath at a pan of sand (think graham cracker crumbs). The student is showing the rest of his class how the wind _____________ teh land.
deposits rocks on
forms soil from
erodes
weathers

• Q5
Wind and water can change rocks over long period of time. How does this happen?
They can change the shape of the rocks.
They increase the mass of the rocks.
They add minerals to the rocks.
They build up the rocks with small sand particles.

• Q6
Wind can cause weathering. How does wind cause weathering?
Wind does not cause weathering on rocks.
Wind picks up sand and carries it from one place to another.
Blowing sand and sediment can wear away a rock's surface and break it down into smaller pieces.
Wind can blow sand and create new landforms.

• Q7
How does a delta form?
Deltas form at the mouth of a river when water slows down and deposits sediment.
Deltas form on the bank of a river when a glacier moves past.
Deltas form at the mouth of a river when wind deposits sand.
Deltas form on the banks of a river when water slows down and deposits sediments.

It will become bigger and less smooth.
It will become smaller and smoother.

• Q11
A student spreads modeling clay in a flat tray. He presses small pebbles and nails into the clay and puts it in the freezer. He pours wax and allows it to harden in another tray. He takes the clay out of the freezer and places it on top of the wax. He applies pressure and drags the clay over the top of the wax and makes deep impressions. Which geologic process is the student trying to model?
divergence of tectonic plates
erosion due to glaciers
formation of volcanoes
weathering of rocks

• Q12
Frost wedging is a form of weathering caused by water seeping into cracks of rocks. This is common in areas that have very cold winters. How does frost wedging take place?
Chemical weathering - water reacts with the chemicals in the rock and the bonds holding the rock together break apart.
Physical weathering - water freezes, the temperature of the rock is decreased and part of the rock falls off.
Physical weathering - when water freezes it expands pushing the rock apart slowly.
Chemical weathering - carbonic acid formed by the reaction of water and carbon dioxide breaks down the rock.

• Q13
Which is an example of chemical weathering?
erosion of land caused by receding glaciers.
deposition of silt along the banks of a river.
the layer of oxide formed on statues made of metal
weathering of rocks in a desert due to the rapid rise and fall of temperature.
