What is the name geologists use to describe the angle that a fault makes with the horizontal?
Geologists refer to the angle that a fault makes with the horizontal as the "fault dip." This angle is measured from the horizontal plane down to the fault surface. The dip is an important aspect of fault geometry, influencing how stress is distributed in the Earth's crust and affecting earthquake mechanics.
Do geologists use creep meter to measure the horizontal movement along a fault?
Yes, geologists use creep meters to measure the slow, continuous movement along a fault. Creep meters are sensitive instruments that can detect even small amounts of movement over time, helping geologists monitor fault activity and study the behavior of faults.
What do faults tell geologists about the relative ages of rock?
A fault must be younger than the rock it cuts through.
When a fault is not vertical a hanging wall and what are formed?
When a fault is not vertical, a hanging wall and footwall are formed. The hanging wall is the block of rock above the fault plane, while the footwall is the block of rock below the fault plane. These terms help geologists describe the displacement and movement along the fault.
Did the fault occur before or after the igneous intrusion?
To determine whether the fault occurred before or after the igneous intrusion, geologists typically analyze the relationships between the rock layers and the intrusion. If the fault cuts through the igneous rock, it indicates that the fault occurred after the intrusion. Conversely, if the intrusion is found within the fault zone or is displaced by the fault, it suggests that the fault predates the igneous intrusion.

What clue tells geologists intrusion?
A clue that tells geologists about an intrusion is the relationship between the rock layers. An intrusion is younger than the surrounding rocks it cuts through, so if the intrusion appears to cut across existing layers, it is likely an intrusion. Additionally, the mineral composition and texture of the intrusion can differ from the surrounding rocks, providing further evidence of an intrusion.
What do geologists use to monitor the upward movement along a fault?
Geologists use instruments like GPS devices, tiltmeters, and creepmeters to monitor the upward movement along a fault. These tools help geologists measure ground deformation and track changes in fault activity over time.

How do geologists learn about the blocks of rock along a fault move?
Geologists use a variety of techniques to study fault movements, such as mapping fault lines, analyzing the offset of rock layers, studying fault rocks, and using geophysical methods like seismic imaging. By analyzing these features and data, geologists can reconstruct the history of fault movements and better understand the behavior of faults.
What is the name geologists use to describe the angle that a fault makes with the horizontal?
Geologists refer to the angle that a fault makes with the horizontal as the "fault dip." This angle is measured from the horizontal plane down to the fault surface. The dip is an important aspect of fault geometry, influencing how stress is distributed in the Earth's crust and affecting earthquake mechanics.
What aspect of mountain building did geologists have trouble explaining?
Geologists have trouble explaining how fold and fault-block mountains came into being.
What clues tell geologists?
Give relative ages of rocks. This is not the only clue to this question
Do geologists use creep meter to measure the horizontal movement along a fault?
Yes, geologists use creep meters to measure the slow, continuous movement along a fault. Creep meters are sensitive instruments that can detect even small amounts of movement over time, helping geologists monitor fault activity and study the behavior of faults.
How do geologists determine the age of a fault line?
Geologists determine the age of a fault line primarily through relative dating techniques, such as examining the rock layers (stratigraphy) adjacent to the fault and identifying which layers have been displaced. They may also use radiometric dating methods on minerals or rocks within or near the fault to obtain absolute ages. Additionally, the analysis of fault-related features, such as offset river channels or specific geological formations, can provide insights into the timing of fault activity. Combining these approaches allows geologists to establish a more comprehensive timeline of fault development and movement.
What two factors help geologists predict an earthquake?
geologist can predict earthquakes by the help of stress along a fault and energy along the fault
How do geologists learn about how the block of rock along a fault move?
They map the earthquakes intensity and where the past earthquakes were.
