Which of the following geologic processes is the BEST evidence that continents change position over time?
A. formation of deltas
B. volcanic eruption
C. erosion by glaciers
D. sea floor spreading
Scientists have observed that when oceanic plates and cotinental plates collide, the oceanic plate is driven under the continental plate. The MOST LIKELY reason for this phenomenon is -
A. the convection currents in the mantle.
B. water applies a downward force on the oceanic plate.
C. the oceanic plate is more dense than the continental plate.
D. the continental plate is wider than the oceanic plate.
To solve this we must be knowing each and every concept related to continents. Therefore, the correct option is option D among all the given options that is sea floor spreading.
What is continents?A huge landmass that is distinguished from other landmasses by seas is referred to be a continent. Seven continents make up the Earth's land mass. Some are connected and split merely by an arbitrary line, while others, like a large island, are completely encircled by sea.
On some continents, there are numerous countries, whereas on others, there are few. The sizes of the continents vary greatly; Asia is larger than Australia by more than five times. Sea floor spreading is the geologic processes that is the best evidence that continents change position over time.
Therefore, the correct option is option D among all the given options that is sea floor spreading.

The oceanic plate is made mostly of granite and limestone.
The theory of continental drift was immediately accepted by the scientific community.
Answer:
1: is one solid land mass, has 7 main plates, is mostly made of silicon dioxide.2: a metamorphic rock.3: cooling magma.4: in dry locations. 5: were connected, are drifting. 6: 4
Explanation:
1:Earth's crust is divided into 7 major and several minor tectonic plates which float on a semi-fluid layer called the asthenosphere. Silicon is the second most common element present in the crust with an abundance of 276,900 ppm. It exists as a compound in the mantle and the crust. In the crust, it exists combined with oxygen to form silicate minerals.2: Quartzite is a hard, non-foliated metamorphic rock which was originally pure quartz sandstone.3:Igneous rock is formed through the cooling and solidification of magma or lava.4:Sedimentary rocks are types of rock that are formed by the accumulation or deposition of small particles and subsequent cementation of mineral or organic particles on the floor of oceans or other bodies of water at the Earth's surface.

Which feature of the ocean floor includes its deepest parts?
trench
estuary
mid-ocean ridge
continental slope
Trench is the deepest part of the ocean.
Ocean trenchOceanic trench, also known as deep-sea trench. It is the narrow, long, steep-sided depression in the bottom of the ocean in which take place the maximum oceanic depths.
It is about of the depth of 7300 to 11000 meters, that is, 24000 to 36000 feet.
They generally emerge in the locations where subduction of one tectonic plate takes place over the other.
The deepest place in the ocean is the Mariana trench, which is of the depth of 36201 feet.

Explanation:
The mass percent of hydrogen in CH₄O is 12.5%.
What is the mass percent?Mass percent is the mass of the element divided by the mass of the compound or solute.
Step 1: Calculate the mass of the compound.
mCH₄O = 1 mC + 4 mH + 1 mO = 1 (12.01 amu) + 4 (1.00 amu) + 1 (16.00 amu) = 32.01 amu
Step 2: Calculate the mass of hydrogen in the compound.
mH in mCH₄O = 4 mH = 4 (1.00 amu) = 4.00 amu
Step 3: Calculate the mass percent of hydrogen in the compound.
%H = (mH in mCH₄O / mCH₄O) × 100%
%H = 4.00 amu / 32.01 amu × 100% = 12.5%
The mass percent of hydrogen in CH₄O is 12.5%.
CO2 = 1.580 grams H2O = 0.592 grams Lookup the molar mass of each element in the compound Carbon = 12.0107 Hydrogen = 1.00794 Oxygen = 15.999 Calculate the molar mass of CH4O by adding the total masses of each element used. 12.0107 + 4 * 1.00794 + 15.999 = 32.04146 Now calculate how many moles of CH4O you have by dividing by the molar mass. m = 1.15 g / 32.04146 g/mole = 0.035891 mole Now figure out how many moles of carbon and hydrogen you have. Carbon = 0.035891 moles Hydrogen = 0.035891 moles *
Therefore, The mass percent of hydrogen in CH₄O is 12.5%.

How do you determine the number of protons, electrons and neutrons in a specific atom?
Answer:
The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.

Which is one step that geologists use to find the epicenter of an earthquake?
They look at data from at least one seismograph.
They measure the difference between arrival of P waves and S waves.
They draw circles around the epicenter from three locations.
They obtain information about the intensity of earthquakes from seismographs
Answer:
B
Explanation:
The one step that geologists use to find the epicenter of an earthquake is; They measure the difference between arrival of P waves and S waves.
Discussion;
Scientists use triangulation to find the epicenter of an earthquake. Upon collection of seismic data from at least three different locations, it can be used to determine the epicenter by identifying where it intersects.
On this note, scientists measure the distance between the first P wave and the first S wave.
