What are the 2 characteristics of sedimentary rocks that reveal the past history of the earth?
Presence of fossils and stratification of the rocks structure into different layers.
Name the three types of rocks?
Igneous, sedimentary, and metamorphic rocks are the three main types of rocks. Igneous rocks are formed from the cooling of molten rock, sedimentary rocks from the accumulation of sediment, and metamorphic rocks from the transformation of existing rocks under heat and pressure.
What are the parts of the rock cycle?
The rock cycle consists of three main parts: 1) igneous rocks are formed from the cooling and solidification of magma or lava, 2) sedimentary rocks are formed from the accumulation and compaction of sediments, and 3) metamorphic rocks are formed from the alteration of existing rocks due to heat and pressure within the Earth's crust.
What are facts about rocks and minerals?
1)Igneous rocks are the oldest among all other rocks. 2)Basalt,formed after cooling down volcanic lava,is one of the most occurring rocks. 3)Some of the rock samples collected from the room were found to be similar to those found on the earth.

What 2 igneous are formed by fast cooling lava?
Two igneous rocks formed by fast cooling lava are basalt, which is a fine-grained volcanic rock, and obsidian, which is a natural glass formed from rapidly cooling lava without crystal growth.
What are the processes involved in the rock cycle?
The rock cycle involves three main processes: 1) Formation of rocks through cooling and solidification of magma or lava, 2) Transformation of rocks through heat and pressure, and 3) Breakdown of rocks through weathering and erosion, leading to the formation of new rocks. These processes continuously interact and recycle rocks on Earth's surface.
What are all the processes involved with the formation of these rocks?
The first process involved with the formation of rocks are that gold and silver are named after a scientist called 'Isaac R' and his last name 'Rosenthaw' is a appreciated scientist with the brains.
The majority of surface rocks are?
Igneous in origin, formed from the cooling and solidification of molten rock material. Sedimentary rocks are also common, created through the compression of sediment over time. Metamorphic rocks are less abundant on the surface but can be found in areas where existing rocks have been subjected to high heat and pressure.
What year did the Grand Canyons rocks form?
The Grand Canyon rocks formed from 2 Billion years ago to the present. The Grand Canyon is an excellent place for studying geology and the history of the earth.
What 5 steps are in the rock cycle?
The rock cycle involves 5 main steps: (1) formation of rocks through cooling and solidification of magma/lava, (2) weathering and erosion breaking down rocks into sediments, (3) transportation of these sediments by natural forces, (4) deposition and compaction of sediments to form sedimentary rocks, and (5) metamorphism of existing rocks due to heat and pressure to form metamorphic rocks.
How does a geographer conclude that 2 phenomena are spatially located?
