1.

the rock cycle relies on to convert rock into usable particles to form other types of rock.

burial

erosion

2.

heat and pressure can turn all other rocks into rocks.

igneous

sedimentary

metamorphic

3.

igneous rocks are formed

through cooling magma.

by burial and lithification.

from metamorphic rocks.

Igneous rock is formed by cooling magma. Sedimentary rock is formed through the lithification process of cementing, compacting, and hardening of the sediments. Metamorphic rock is formed by metamorphosis of igneous and sedimentary rocks.

Explanation:

The rock cycle refers to the cyclic process that leads to the formation of three different types of rocks namely the igneous, sedimentary and the metamorphic rocks, and also their alteration from one rock type to another under certain factors and conditions.

In order to form another type of rocks that are to be deposited in some other environment, the source rock must undergo the process of weathering and erosion. Weathering leads to the breakdown of rocks and erosion leads to the transportation of the broken fragments and sediments. This new sediments after deposition and lithification will give rise to the formation of sedimentary rocks such as Sandstone and Limestone.

The rocks that are formed under extremely high pressure and temperature condition are usually known as metamorphic rocks. These are directly obtained from the previously existed sedimentary or igneous or other metamorphic rocks. So they are also known as secondary rocks. For example, Quartzite, Schist, and Gneiss.

The rocks that are directly derived from the cooling and solidification of magma are known as igneous rocks. When these rocks are crystallized below the earth's surface then they are called intrusive igneous rocks, and when they crystallized on the earth's surface then they are called extrusive igneous rocks. For example, Granite and Basalt.

Thus, the correct answers are mentioned above.

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
