Intro quiz - Recap from previous lesson

Before we start this lesson, let’s see what you can remember from this topic. Here’s a quick quiz!

Q1.A hydrograph shows...

How much sea water is on Earth. How river discharge changes overtime, in relation to rainfall. When a storm event will occur.

1/6

Q2.Lag time is...

The highest amount of rainfall (the highest bar on the hydrograph). When river discharge is at its highest, within the given time frame. The time delay between the peak rainfall and peak discharge.

2/6

Q3.The rising limb shows...

The increase in river discharge as rainwater enters the river channel. The decrease in river discharge, as the river returns back to normal (base flow). Water flowing over the land.

3/6

Q4.A short lag time means...

Rainwater is entering the river channel very slowly. Rainwater is entering the river channel very quickly.

4/6

Q5.Impermeable soils and rocks do not allow...

Infiltration and percolation. Precipitation. Urbanisation.

5/6

Q6.Deforestation reduces...

Surface runoff. Interception and transpiration. Urbanisation.

6/6
