In physical development,a child will most likely experience a growth spurt.Explain the concept of a growth spurt.

Puberty ushers in the most rapid increases in growth since infancy.It happens about 2 years earlier for girls (9 years old)than for boys (11 years old).Boys and girls who are shorter or taller than their peers before adolescence are likely to remain so during adolescence.Girls increase in height at a rate of about 3.5 inches per year while boys increase their height by about 4 inches during the growth spurt.Weight gain also coincides with height gain.In early adolescence girls usually outweigh boys,but that changes when boys have a spurt in their weight gain in later adolescence.Body shape also changes.The hips change in girls and in boys shoulder width increases.
