The rock is conglomerate. The other rock would be Breccia if its grains were not rounded.

Why can two rocks look very different even though they have the same minerals?
The two rocks in question may have different percentages of the same minerals, or their method of formation could be different, which can affect the shape and size of the mineral grains. Trace minerals in the two rocks could also alter their appearance, as well as the amount of weathering the rocks have been exposed to.
Is it possible for two igneous rocks to have the same mineral constituents but different names?
Yes, depending on the conditions under which it solidified.
How do two igneous rocks have the same mineral composition but different textures?
The texture of an igneous rock refers to the size of its mineral crystals. If the common magma of both igneous rocks has experienced differences in cooling rates due to depth, they will have different textures. Slow cooling produces large crystals, and quick cooling produces small crystals. Granite and rhyolite are two igneous rocks sharing the same mineral composition, but having undergone different rates of magma cooling due to depth at solidification.
What texture is igneous?
igneous is the texture of igneous rocks. The texture of igneous rocks is defined by 3 ways: a) Crystallinity- it expresses the degree of formation of crystals in an igneous rock. the texture of an igneous rock may be Holocyrstalline (Completely characterised by crystals, Hemicrystalline (partially having crystals) and holocrystalline (no crystals). b) Granularity- it is the size of the grains. it may be equigranular (when mineral grains are equal in size) or inequigranular (when mineral grains are not equal in size). c) shape of crystals- The shape of crystals may be Euhedral (When all crystals are of same shape), Subhedral (when they are partially similar in shape), Anhedral (when they are completely different in shape).
What kind of sedimentary rock is made of fragments of rocks cemented together by a mineral?
Breccia is the type of sedimentary rock that is made of other fragmented rocks. The mineral that holds the fragments together can be made from the same rock material as the larger fragments, or from a different type of rock entirely.
Why do igneous rocks that have the same composition sometimes have different sizes of mineral grains?
This is as a result of difference in the rate of cooling of the Igneous rocks.
Can two igneous rocks be made of the same minerals but have different names?
Yes. The grain texture also matters. For example, basalt and gabbro have the same mineral composition, but basalt, which forms on the surface, has microscopic grains while gabbro, which forms underground, has larger mineral grains.
Why are rocks not the same?
Because different rocks are formed by different processes and made up of different mineral assemblages.

Trace minerals in the two rocks could also alter their appearance, as well as the amount of weathering the rocks have been exposed to.
Why are all rocks different sizes?
All rocks are not the same in that they are formed in a variety of ways, and are comprised of an array of mineral assemblages.
Is a rock and a mineral the same?
No. Rocks are combinations of minerals.

Metamorphic rocks with the same mineral assemblages belong to the same?
metamorphic facies
Is a rock and a mineral the same thing?
No. Rocks are combinations of minerals.
What is the least reliable way to classify a mineral?
color for instance real gold and fools gold is the same color but 2 different rocks
