A sedimentary rock made up of rock fragments with rounded edges is called  Conglomerate.

Explanation:

Sedimentary rocks are rocks usually formed from preexisting rocks or remains of plants and animals. This rocks are formed from through weathering and erosional degradation.

Conglomerates are clastic sedimentary rocks with usually rounded edges. Clastic sedimentary rocks are rocks made up of pieces of preexisting rocks. The particles of the preexisting rocks are loosened by weathering and later this individual particles become cemented by a binding agent.

Conglomerates has large clast(grains) and usually quartz and calcite bind the particle together. The rounded clasts can be a mineral composition of feldspar and quartzite, formed from igneous , metamorphic and sedimentary rocks. This rocks are formed from the accumulation of this rounded clast and the availability of cementing agents like calcite to bind the particles together.

The picture above is a conglomerate rock .  

(bro she is ancient)

j < 14

j is jakes age

since jake is younger it makes his age less than his sisters

(if you meant she is 14)
