Which rock type is formed from hardened magma beneath the Earth’s surface?

Which of the following represents the correct order of the processes responsible for the formation of sedimentary rocks?

A student obtained a cup of quartz sand from a beach. A saltwater solution is poured into the sand and is allowed to evaporate. Afterward, the mineral residue from the saltwater solution cemented the sand grains together. Which of the following is most likely formed?

Which of the following is true about rocks?

What is the type of rock formed from lava that cools quickly that results to finer grain and smaller size of crystals?

Halite is made when a body of seawater becomes closed off and evaporates and salt precipitates out and is deposited as crystallized halite. What type of sedimentary rock is formed?

A magma came out from a volcano through a Strombolian eruption. Afterward, the lava cools down and forms igneous rock. Due to varying temperature and weather conditions, these igneous rocks were transformed into sediments that form limestone later on. Another eruption occurred. Limestone was subjected to extreme heat and pressure so marble was formed. What is the correct order of geologic processes that occurred in this event?

Identify the series of geological processes that can transform sediment into shale, shale into slate, and slate into magma.

 According to PAG ASA, the center of typhoon Ulysses was at 1,960 km East of Central Luzon with a speed wind of 213km/h. This strong wind causes a rock to fall and its pebbles, dust, and sand particles are carried away to different places. What type of erosion is depicted in the given situation?

A strong wind caused by Typhoon Carpiocauses pebbles, dust, and sand particles to be carried away on a nearby stream. The stream eventually brought the sediments into a lake where it is compacted and cemented together, forming a clastic rock called conglomerate. What type/s of erosion is shown in the given situation?

Rocks and sediments are picked up and moved to another place by ice, water, wind, or gravity. What geological process best describe this scenario?

When does weathering happen?

ALL BUT ONE of the following is an example of biological weathering. Which ONE?

Your Earth Science Teacher asked you to give an example of Chemical weathering. Which of the following can you possibly give?

Which type of mechanical weathering is due to gravity?

How does extreme temperature cause mechanical weathering?

Leaching is the process whereby water dissolves minerals and rock materials combined with the solution. Based on the statement, leaching is an example of what type of weathering?

ALL BUT ONE of the following is an example of chemical weathering. Which one?

ALL BUT ONE of the following is an example of mechanical weathering. Which one?

Burrowing animals like rabbits can burrow into a crack in a rock, making it bigger and splitting the rock. The broken rock fragments fall into the ground and are carried away by the wind into a nearby stream. The flowing water of the stream brought the fragments into the coastline where it settles at the bottom. Identify the series of events that happen.

Carbon dioxide in rainwater that dissolves limestone is an example of ________.
