there are two orange + signs on the west coast of the united states. click the one that is higher (washington state) and answer the following:

1. which tectonic plate interaction caused the mount saint helens eruption of 1980? :
2. what had been happening the months before the eruption?:

Explanation:

To answer these questions, you need to visit the provided website (https://www.amnh.org/explore/ology/earth/plates-on-the-move2/game) and follow the instructions for each section (Alaska, Hawaii, Washington state). Here's a general guide on what to expect for each question based on plate tectonics knowledge:

Alaska Section

1. Tectonic plate interaction for 1964 Alaska earthquake: Subduction (the Pacific Plate is subducting beneath the North American Plate).
2. Triggered events and affected locations: The earthquake triggered tsunamis that affected coastal areas of Alaska, the Pacific Northwest (e.g., Oregon, Washington), and even reached as far as Hawaii and Japan. Landslides also occurred in Alaska.
3. Interacting plates: Pacific Plate and North American Plate.

Hawaii Section

1. Tectonic plate interaction for Hawaiian Islands: Hotspot (plume) activity (not a typical plate - plate interaction like subduction or collision; the Pacific Plate moves over a stationary hotspot in the mantle).
2. What is a “hot spot”: A hot spot is a stationary area of intense volcanic activity in the mantle, where magma rises to the surface. As a tectonic plate moves over it, a chain of volcanoes (like the Hawaiian Islands) forms.
3. Future of Hawaiian Islands: As the Pacific Plate continues to move over the hotspot, the existing islands will erode and sink, while new islands will form to the southeast (in the direction the Pacific Plate is moving).

Washington State (Mount Saint Helens) Section

1. Tectonic plate interaction for 1980 eruption: Subduction (the Juan de Fuca Plate is subducting beneath the North American Plate).
2. Events before the eruption: There were months of seismic activity (earthquakes), ground deformation (the mountain swelled as magma accumulated beneath it), and gas emissions.

To get the exact answers, you must interact with the website and follow its prompts. The above explanations are based on standard plate tectonics concepts to guide your exploration.
