number and color
size and hardness
size and angle
Answer:
A. - angle and number
Explanation:
(>-<)
The size of the crystal faces and the angle between them define the crystal system. Therefore, option (D) is correct.
What is a crystal system?A crystal system indicates many classes of crystals, space groups, and lattices. In crystallography terms, crystal system and lattice system are associated with each other. The crystals based on their point groups are divided into seven crystal systems.
The seven-crystal system is the Cubic, Tetragonal, Hexagonal, Orthorhombic, Monoclinic, Triclinic, and Rhomohedral systems. The classification of Seven Crystal Systems is depending upon their lattice and atomic structure.
The size and length of their surfaces which are known as ‘faces’ and sides, and the angles between them, define the shapes of crystals. The cubic crystal system is the most symmetrical as all the angles and the length of the edges is equal.
While the triclinic is the most unsymmetrical crystal system as all the lengths and the angles between faces are unequal.

D. Planets formed from small amounts of debris that were attracted together because of gravity.
A dense cloud of interstellar gas and dust formed our solar system roughly a billion years ago. A solar nebula—a whirling, swirling disk of material—was produced when this dust cloud collapsed. Gravity drew more and more material into the center. The sun was still forming and planets had not yet been created when the solar system was very young. The solar system consisted primarily of gas and dust.
D. Planets formed from small amounts of debris that were attracted together because of gravity.

Protons Neutron and electrons witch of these are responsible for a charge that can be transformed from one object to another.
Answer:
Explanation:
In a tropical rain forest, tall trees crowd together, blocking the path of sunlight to the wet forest floor. Among the plants adapted to these conditions are climbers, such as vines that grow up along the tree trunks. Other plants, such as orchids, grow attached to tree branches and are not rooted in the ground. Even a small area of forest provides various habitats for vast numbers of animal and plant species. Many insects and birds are plant pollinators. Fruit-eating animals, such as birds and bats, spread seeds. Insects, fungi, and bacteria break down plant and animal matter, releasing nutrients into the soil. Predators, such as jaguars and snakes, feed on smaller animals.

Explanation: Because how would they hunt.
Biotic and abiotic factors both are dependent on each other.
What is biotic and abiotic factors?Biotic factors are living things within an ecosystem; such as plants, animals, and bacteria, while abiotic are non-living components; such as water, soil and atmosphere.
Abiotic factors in a tropical rain forest include water, a warm climate, sunlight, and soil nutrients. All organisms and populations in the tropical rain forest depend on water and warm temperatures. Plants depend directly on sunlight and soil nutrients.
Biotic factors in a tropical rain forest include all of the organisms that live there. Vines and orchids depend on the trees as a way to reach the light.
Some plants depend on insects or birds for pollination, or birds or bats to spread their seeds. Indirectly the plants depend on organisms that release nutrients into the soil.

Which phrase describes non-foliated rocks?
have grains in parallel layers
include quartzite and marble
tend to split along their bands
form from crystallized magma
Non-foliated rocks include quartzite and marble. Therefore, option (B) is correct.
What are the non-foliated rocks?Nonfoliated rocks less foliated texture because they commonly lack platy minerals like micas. They often result from regional metamorphism. Examples include quartzite, marble, hornfel, greenstone, and anthracite.
Marble is low to high-grade metamorphosed dolostone or limestone both of which are carbonate rocks, They are made of dolomite grains or interlocked calcite. Marble is very often carved in the artwork of palaces.
Quartzite is quartz sandstone that is medium to high-grade metamorphism. It is composed of interlocking grains of quartz and can be distinguished from sandstone because individual grains do not fall off during the rock is rubbed. Original sedimentary structures in quartzite will remain visible.
