In Forney, a new concrete road has suddenly become cracked in places. Recent weather has been particularly wet and very cold with temps dropping below freezing during the nights. What has caused this to take place?

• During rainfall events the water runs off the roadway but undercuts the road and works its way under the road and erodes the base course causing cracks in the surface of the road.

• Concrete is very strong and is not able to crack under the stress of vehicle weight.

• During rainfall events the water has seeped into tiny cracks and pores in the surface of the concrete and below freezing temps have caused the ice to expand and crack the surface of the road.

• None of the above

What is an Ecoregion?

• an area that is defined by a certain climate and certain animal, and plant species live within that area.

• a region of land that weathering, erosion, and deposition occur at an advanced rate thereby causing more species to adapt to the conditions in the area.

• new areas of the country formed by our government that allow farmers to produce "eco-friendly" crops, thereby allowing a more sustainable erosion free area

• none of the above

Water in a river is flowing the fastest in what part of a curve?

• inside of the curve

• water flows at a constant rate in all parts of the river

• middle of the river

• outside of the curve

What makes a river meander?

• weathering caused by increased water flow

• Deposition and erosion of sediment

• the sizes of sediments are reduced and the smaller sediment sizes cause the river to meander

• none of the above

A Barrier Island is long narrow island lying parallel and close to the mainland, protecting the mainland from erosion and storms. How are barrier islands created?

• a portion of the mainland is broken off because of plate tectonic movement; this creates a small barrier island

• waves and ocean currents carry sand and sediments and deposit them over many years causing a barrier island to form

• ocean currents shift and change direction causing the waves to reverse course and flow in the opposite direction and backfill sand creating a barrier island

• none of the above
