Answer:
surface drainage systems
Explanation:
Karst is a kind of topography that is formed from the dissolution of soluble rocks (e.g. limestone, dolomite, and gypsum). It is composed by an underground drainage systems with sinkholes and caves, so a stream cannot be formed in this kind of topography.
The solubility of limestone in water and weak acid solutions leads to karst landscapes. Flowing rivers, can be found in areas away from karst topography. Sinkhole is not associated with areas of Karst topography.
Karst topography may contain sinkholes or funnel-shaped holes in the surface of the land, caverns, caves, and underground rivers. Karst topography varies greatly, from steep jagged cliffs to soft rolling hills; from microscopic in size to hundreds of square miles. Karst regions are found all over Earth.

Explanation:
Answer: B. Metamorphic rocks
Explanation: Metamorphic rocks are those that have undergone changes due to extreme heat and pressure. Thus, the rock, from which it becomes a metamorphic rock, is heated at temperatures above 150-200 ° and exposed to a pressure of 1500 bar. In this way, the structure of the rock is changed, in terms of the arrangement of the atoms, and the result is a change of physical and chemical properties. There are two basic types of metamorphic rocks: foliated and slate. Generally, some of the metamorphic rocks are anthracite, schist, quartzite, marble, etc.
Answer: The Solar System
Complete Question:
This is the Sun and the celestial objects bound to it by gravity. This includes the eight planets and their 166 known moons,four dwarf planets, and billions of small bodies, including asteroids, comets, meteoroids, and interplanetary dust.
Explanation:
The Solar System is made up of the sun which is a star, the eight planets of which earth is one, smaller planets including Pluto, moons, and hundreds of thousands of other smaller bodies. These smaller bodies include asteroids, comets, meteoroids, and interplanetary dust.
Our solar system is in the Milky Way Galaxy, circling its center at over 500,000 miles per hour. To have an idea of how massive the galaxy is, it takes our solar system, even at this speed, 230 million years to complete an orbit.
