The t distribution is used instead of the normal distribution when sample sizes are small. It is flatter and more spread out than the normal distribution for small sample sizes, becoming more like the normal distribution as sample size increases. This accounts for the increased uncertainty (and thus wider confidence intervals) when estimating population parameters from small samples.
