Explanation:
first I want to tell you that for 5 point except me nobody is going to give answer
so I am giving answer and you have to follow me and mark it brainliest ok
D 1. The single most important feature of sedimentary rocks is their layering structure. This is important because their layers help geologist understand historical events that occurred in the past
2. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors
3. Lava is molten rock generated by geothermal energy and expelled through fractures in planetary crust or in an eruption , usually at temperature from 700 to 1200 celcius
4. Igneous rocks are known as primary rocks as they are formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust.
5. Sediment is solid material that is moved and deposited in a new location. Sediment can consist of rocks and minerals, as well as the remains of plants and animals.

1) P waves travel through any kind of material, whether it is a solid, liquid or gas. On the other hand, S waves only move through solids and are stopped by liquids and gases. ... This also accounts why fewer S waves are recorded than P waves.
2). It has volume. The typical composition is basaltic rock (beneath most oceans) and granitic rock (most continents) with lesser amounts of sedimentary rocks (both ocean and continental crust) and metamorphosed rocks. The upper surface of the crust is typically weathered and eroded, or deeply weathered, to soil.
Some of the characteristics of the mantle:
It is 82% of earth's volume.
It is 2885 km thick.
It is composed of basaltic (ultramafic) rock and minerals such as olivine, peridotite, and pyroxene.
It is stratified into three main layer
It's Almost The Size of the Moon. The Earth's inner core is surprisingly large, measuring 2,440 km (1,516 miles) across. ...
It's Hot...Really Hot. ...
It's Mostly Made of Iron. ...
It Spins Faster Than the Surface of the Earth. ...
It Creates a Magnetic Field.
3) fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing organic molecules originating in ancient photosynthesis that release energy in combustion
4) Knowledge of the earth's interior is based on indirect observation as it is impossible to collect data regarding the earth's interior, we can't dig on such a great extent ,as their is intolerable heat deep inside the earth and it is impossible for any organism to survive their.. Therefore the the observation includin
5)
mineral is an element or chemical compound that is normally crystalline and that has been formed as a result of geological processes.
Using Characteristics of Minerals to Identify Them. Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.
